European Communications discusses the latest telecom trends with telco executives, analysts and topic experts viainsightful analysis, Q&As and opinion pieces.

Foreword - Brussels clout?

Proposed EU telecoms regulation has already divided opinion on its potential impact, says Lynd Morley

As Europeans, do we want more or less centralised control and regulation? It is a seemingly endless debate, with passionate positions and justifications taken on both sides of the argument. And telecoms is by no means an exception to the ongoing and far-reaching grasp of Brussels.
During the summer, the Commission launched its public consultation on policy options for updating the EU's telecom rules of 2002, the “regulatory framework for electronic communications”. Electronic communications – by the EU's definition – include fixed voice telephony, mobile communications and broadband – a market worth more than E270 billion in the EU in 2005.
Viviane Reding, the EU Commissioner responsible for Information Society and Media, set out a number of recommendations for the telecoms industry, including a clear demand for greater consistency in the regulatory approach to telecoms across the various member countries.  Mutterings about more centralised control and “Brussels' overreaching bureaucracy” could be heard as soon as the text of her recommendations hit the wires.
Her argument, of course, is not one of control freakery, but of establishing a fair and effective internal market.
“I want to make a decisive step towards the completion of the internal market,” she explained. “In the telecom sector, where neither technology nor economic interest nor consumer behaviour know national borders any more, I see a clear, long overdue need to make the internal market a reality also in regulatory terms.”
She went on to stress that greater consistency and effectiveness in the application of remedies is needed to avoid distortions of competition in the internal market. “We need this consistency” she stressed, “not for the Commission but for the market and consumer, and I hear this all the time from telecom companies that are trying to break into markets beyond their home country.”
Reding insisted that variations of regulatory approach are currently an obstacle to the internal market and to effective competition. “I believe that the Commission should be able to ensure consistency in remedies proposed by national regulators to enhance competition in markets dominated by one or more operators. This is a  logical adjunct to our current role as regards market definitions and market power assessments.”
And just to give her message to the regulators an extra little push, she added: “I also plan to tighten up the timescales in which regulators must act, in order to avoid the long delays that we have seen in some countries.”
Reding believes that the most effective way to achieve a real level playing field for telecom operators across the EU would be to create an independent European telecom regulator that would work together with national regulators in a system similar to that of the European Central Banks.
Not everyone will be thrilled with this suggestion, according to such commentators as Ernst & Young's Richard Ireland, who notes that the move “will doubtless upset national regulators, some of whom have already questioned EU proposals such as a cap on retail mobile roaming prices.” 
Ireland explains that the EU argues that new regulation will increase investment, but that incumbents beg to differ. “Deutsche Telekom's recent refusal to open its prospective fibre optic network is a case in point,” he comments, “one that highlights the potential problems in countries where governments retain stakes in former monopolies. In fact, the EU proposal to introduce the new Europe-wide telecoms regulator is designed to prevent such disputes at a national level.”
Certainly, Reding shows some considerable determination to bring regulators – and some national governments – into line. Expanding her thinking on the creation of an independent European regulator, she explained: “In such a system, national regulators would continue to act as direct contact points with operators and could directly analyse the market. At the same time, a light European agency, independent from the Commission and from national governments, could ensure by guidelines and, if necessary, instructions that EU rules are applied consistently in all Member States.”
Whether Reding's proposals do indeed result in a level playing field, or simply more control from Brussels, remains to be seen.

Fibre in NGN - The X-Factor

Across the world, carriers and ISPs are investing huge sums in next-generation networks, offering uninterrupted and cost-efficient bandwidth to subscribers. And the network’s Layer 1 infrastructure is a key element of such future networks. In a competitive market, vendors are constantly improving the quality and reliability of plugs, cable patches and connector modules. Thus the argument for FTTx as a roadmap for network infrastructures is becoming clear, claims Martin Kellenberger

We may not often think of it nowadays, but at the bottom of the network infrastructure is Layer 1 – and this is a hotly contested market. Connectors, patches and distribution components are all basic parts of building a secure network, and the choice of reliable manufacturer is increasingly being viewed as a tactical – or even strategic – issue by many industry insiders.
A key aspect of Next Generation Networks is the forecast growth in data traffic due to new IP-based bandwidth intensive applications. When making plans to meet this demand, cost has to be considered and fibre optics has a strong case here. Active devices and components for fibre optic networks have a higher purchase price, yet delivery and durability make for a better long-term cost calculation than copper-based infrastructures.
Today’s widely installed TDM infrastructures are optimised for voice traffic and, as we know, they are rather inappropriate for commercial implementation of the next generation of packet-based IP services.
The benefits of fibre optics compared to other transmission technologies make fibre a compelling technology for future high bandwidth applications such as Fibre-to-the-Home (FTTH), Fibre-to-the-Premise (FTTP), Fibre-to-the-Curb (FTTC) – or summarised FTTx.
FTTx is eminently poised to be the networking industry standard due to its advantages:
• The continually accelerating reduction in costs associated with fibre deployment
• PON (Passive Optic Network) means no active components between end user and CO (Central Office)
• An increasing demand for voice, data, and video services on a single fiber
• Fibre’s superior reliability, scalability, and security
• Fibre’s status as a future-proof architecture
Forward-thinking vendors are working with a broad range of innovative fibre technologies that will bridge the gap effectively between network transmission and access demands. Fibre optic connections and secure distribution is the basis on which the global networked community will add new features and services at lightning speed, while generating vast new revenue streams.
With the growth in consumer demand for high-speed bundled services such as HDTV, FTTx has been recognised as the ultimate solution. Twisted pair, coax, and hybrid fiber/coax (HFC) networks are not as future-proof as FTTx architecture.
With the continually declining costs of optical equipment FTTx is a technology to watch as it gains the interest of service providers. Its compelling advantage is the creation of a passive optic network (PON) in which all components are passive and can be said to merely provide throughput.
There are no active components in between the central service delivery in the network CO to the end user. This dramatically minimises network maintenance cost and requirements as well as eliminating the need for a DC power network.
It allows the service delivery and management to take place across a single fibre to the end user, providing revenue-generating services with industry standard user interfaces, including voice, high-speed data, HDTV, and video on demand.

Technology available
Traditionally, vendors and buyers of fibre optic components have tended to segregate the market according to quality grade but this is not optimal.
It is possible that a customer bought and is using ‘too good’ a product and that the application could have functioned with less costly equipment. Conversely – and this is even worse – it is possible that components installed are incapable of supporting increased requirements of the service delivery or system-specific capabilities.
Perhaps there is a lack of knowledge in the market – or perhaps it is not sufficiently career-enhancing for any network engineer to dwell too long on Layer 1 discussions –  in any case we believe that equipment and know-how for Next Generation Networks are already available in the market, to a higher extent than many realise.
It is worth making an effort to push carriers and ISPs to increase their uptake so that more subscribers will realise the benefits of new services through NGNs.
NGN deployment must support a variety of possible access points – they can be as diverse as home, corporate premises, campus or curb or wireless hotspots. Communication requirements are changing and networks must be capable of more than just providing bandwidth.
The need for comprehensive technical solutions increase – as does the significance of every single component. Performance and quality of the fibre optic components play a central role in delivering the required data transmission reliability and bandwidth to future generations.
Successful production of such high-class components builds on technological excellence and insight into fibre optics physics, and on highly automated production processes.
It is certainly advisable to check for product reliability before you start sending your business-critical data down the wires. To ensure quality, R&M has focused on developing high automated assembly plants with multiple quality testing procedures for each step of the fibre optic and copper production process.

Component management
At R&M, we have focused on the NGN challenges for several years now. We’ve looked ahead in the development of fibre optic as well as copper distribution systems and both technologies have improved vastly over recent years.
Fibre Optic Management System (FOM), xDSL and Triple Play solutions particularly stand out as the areas in which network operators are willing to invest.
With FOM installations, network operators gain a significant advantage regarding convenience and security in distribution systems for fibre optic networks. Handling and management of the connections are considerably simplified and secure.
In turn, the technology provides the foundation for building and installing the network infrastructure. With the right components, a network can be equipped quickly and effectively and thus become more profitable.

Broadband events preview

Following a comparatively quiet summer, the conference season begins to pick up pace again at this time of year.  Not surprisingly, a fair number of them are set to address the wide ranging opportunities that broadband presents to the telecoms industry.

At CNIT La Defense in Paris, the Broadband World Forum Europe features over 100 exhibiting companies, covering some 2000 square meters of exhibition space, as well as an extensive conference programme which includes a variety of keynote presentations from the likes of Alain Maloberti of Orange, Alcatel’s Mike Quigley, Roland Kittel of Deutsche Telekom, and Greg Douglass from Accenture. Chaired by France Telecom’s Jean-Philippe Vanot, the conference also offers more than 40 individual breakout session, as well as Plenary Panels, Hot Seat Sessions and Industry Overviews.
The focus of the event is on content development, technology and business sessions programmes particularly highlighting Europe’s leadership in wireless technology and applications unique to the European market.
Complementing the Broadband World Forum is the WiMAX GlobalCom Forum, aimed at the latest developments in the area of fixed and mobile wireless services.
Broadband World Forum, CNIT, La Defense, Paris, October 9-12 2006.  Details: www.iec.org.

In Berlin, a little later in the year, VON Europe is set to address not only VoIP, but also the transformation of communications driven by IP convergence – from IMS to IPTV, Voice over WiFi, Wimax and more.
The Conference, which runs for three days, will cover such topics as Profitability of Broadband Networks, IPTV Architectures, IMS Form vs IMS Function, The IP Based Contact Centre, and VoIP Secrets of Success, and will feature such speakers as Stephan Scholz of Siemens, Deutsche Telekom’s Voker Binder, Grant Lenahan of Telcordia, Skype’s Jonathan Christensen, and Yahoo’s Jeff Bonforte.
VON Europe has grown fairly rapidly in recent years – from an attendance of 1000 executives from 38 countries at the London event in 2004, to 3600 attendees from 68 countries in Stockholm in the Spring of 2006.  The aim of the event, according to the organisers, is to build communities to network and share strategies that result in invention, implementation and distribution of technology that will underpin future success.
VON Europe Autumn, ICC Berlin, November 6-8 2006.  Details: www.voneurope.com

In Moscow, the organisers of the Broadband Russia and CIS Summit believe their event offers a fantastic opportunity for companies to broaden their contact base and network with Russian and CIS industry leaders, while delegates can also obtain first-hand information on the latest trends and developments in the sector. Supported by the Ministry of Information Technologies and Communications of Russia, the Federal Agency of Information technologies of Russia, the Federal Anti-Monopoly Service of Russia, and OJSC Rostelecom, Broadband Russia features over 50 broadband technology stands and displays in the conference networking area, as well as the two-day conference.
The event conference features some 40 speakers, covering such topics as IP over Satellite and Broadband, DSL Access Technologies, ISPs, WiMAX LAN, Multimedia VoIP, Video and Data Technology, IPTV, Wi-Fi, Legal and Licensing Framework, Regulatory Issues, and Policy Reform, and with participation from such countries as Russia, Kazakhstan, Kyrgyz Republic, Georgia, Azerbaijan, Armenia, and Turkey, provides an effective overview of telecommunications in the region.
Certainly the region offers huge potential for telecoms.  In Russia alone, annual growth of the telecoms sector is running above 20 per cent, and having by-passed the heavy investment made by the West into what is now an obsolete telecoms technology in the 1980s and 1990, Russia is in a strong position to capitalise on more recent developments in broadband and wireless communications. Indeed, the number of broadband users in 2005 totalled 5.5 million, an increase of 47 per cent. Internet Access Services accounted for 10 per cent of broadband revenue, and this is expected to rise to 36 per cent in 2008.
The sector remains potentially one of the most rewarding for foreign investors and manufacturers.

Ethernet migration path - Special delivery

Ethernet can be carried over just about anything. And for service providers, that is both an opportunity and a challenge, says Patrick Dolan

With its ubiquity, economics and speed, converging services over Ethernet is a hot trend among service providers and enterprises alike. For enterprises, Ethernet offers more bandwidth than traditional business services at a reasonable price. Those benefits are among the reasons why Ethernet is a major, long-term opportunity for service providers. According to an April 2006 Infonetics Research report, worldwide revenue from Ethernet services more than doubled to €4.6 billion between 2004 and 2005. The report also estimates that revenue will increase to €17.6 billion by 2009.
For service providers to capitalise on that opportunity they must develop a seamless Ethernet migration path and offer services even when there are disparate delivery infrastructures. For example, a typical regional or national carrier will have Synchronous Digital Hierarchy (SDH) in some places, copper or direct fibre in others and Internet Protocol/Multi-Protocol Label Switching (IP/MPLS) in still others. This blend of infrastructure and technologies presents three key challenges to the goal of delivering wide-area ‘Ethernet over anything’:
•  The need to assure seamless Ethernet interworking across disparate physical and transport media. This interworking should leverage the service provider’s and customer’s existing infrastructure instead of requiring expensive forklift upgrades;
•  The need for end-to-end provisioning and fault management visibility to provide Ethernet quality of service (QoS) across those infrastructure boundaries; and
•  The need to protect existing Asynchronous Transfer Mode (ATM), Frame Relay and Time Division Multiplexing (TDM) revenues while migrating to high quality, lower cost Ethernet services.

The multiservice access approach
One reason why enterprises are migrating to Ethernet is speed. The catch is, although service providers often have Ethernet access routers capable of delivering Gigabit throughput, their customers often are not connected by multi-gigabit optical links.
Instead, branch offices and small and medium enterprises (SMEs) typically rely on 2.048 megabits per second (Mbps) E-1 connections that carry Frame Relay or integrated Frame Relay and TDM traffic. Many business customers will not respond to Ethernet services that work only over fiber. This lack of responsiveness is due to the proliferation of copper-served enterprises in Europe. Although SMEs might not have the cachet of major enterprises, the sheer number of them represents a vast market. Any Ethernet solution limited to fiber access will miss millions of opportunities.
Service providers who migrate to Ethernet cannot afford to ignore or abandon copper-connected enterprises. To serve this market, service providers must do two things:
•  Add support for copper interfaces to their Ethernet access routers; and
•  Enable the interworking of Ethernet with popular existing access protocols such as ATM, Frame Relay and TDM.
Multiservice edge routers enable service interworking by incorporating access-side interfaces to existing protocols, with a full range of optical and copper connections. Also known as Layer 2/3 switches, multi-service edge routers support service providers’ existing transport protocols, such SDH, Gigabit Ethernet (GigE) and 10GigE transport.
Multiservice interworking eliminates the need for several overlay backbone networks. It collapses multiple network elements into a single edge router that aggregates all traffic onto a single MPLS backbone. This design reduces network costs and complexity, improving a service provider’s competitive position. Multiservice interworking benefits enterprise customers because they can continue to leverage their existing technology choices while enjoying the benefits of Ethernet.
The multiservice access approach also offers private networking options and helps address security concerns. Typically, Layer 3 Virtual Private Network (VPN) services offered via a standard Ethernet platform are highly flexible. However, the partitioning of one VPN from another creates concerns about security and shared capacity. This concern about security is because these types of router-based VPNs are delivered over infrastructure shared by multiple customers. By comparison, physically separate Layer 2 Frame Relay or ATM transport can be more reassuring to enterprises, such as banks, that place a premium on security.
The multiservice edge router solves this dilemma by offering Layer 3 VPN and Layer 2 Virtual Private LAN Service (VPLS) for customers that demand private network separation at the transport layer. The multiservice edge router can offer the best of both worlds: Layer 2 switching and QoS capabilities, with the flexibility and intelligence of Layer 3 routing. This combination makes Ethernet WAN services more secure, reliable and flexible in the eyes of CIOs and IT managers.
Given the prevalence of copper-base network infrastructure, a service provider’s Ethernet strategy should leverages copper to target enterprises that do not need 10/100 megabit and gigabit speeds. Digital Subscriber Line (DSL) technologies such as Asymmetric DSL 2+ (ADSL2+) and Very High Data Rate DSL (VDSL) are gaining traction in the residential market for triple playservices. However, these technologies also can be used to serve enterprises that are not connected by fibre. For enterprises that require high bandwidth, another option is circuit-bonding technologies that enable multiple twisted pairs to deliver multi-megabit services.

The QoS factor
Quality of Service (QoS) is critical for any offering aimed at the enterprise market. Ethernet’s guaranteed, per-flow QoS enables a service provider to differentiate itself from competitors that use non-guaranteed, class-of-service (CoS) routing. QoS is also important for selling Ethernet services to enterprises that use bandwidth-intensive or latency-intolerant applications such as real-time video.
Due to technological limitations, traditional enterprise-based Ethernet platforms lack the deterministic © QoS necessary to support premium services. Furthermore, these Ethernet platforms cannot offer, enforce, document and charge for differentiated service level agreements (SLAs). Even with the aid of IP/MPLS, Ethernet only can control service classes rather than the per-session QoS controls premium services require.
One solution is to overbuild the network to ensure that there is always enough headroom to guarantee sufficient bandwidth for demanding applications. The downside to this approach is the cost of additional infrastructure and capacity. Some of the excess infrastructure might go unused and not generate enough revenue to recoup the investment, let alone turn a profit.
To make their Ethernet offerings competitive, service providers’ must deliver the same level of QoS as existing technologies such as ATM, Frame Relay and TDM. For example, to match ATM’s QoS, Ethernet must support per-session deterministic QoS mechanisms. These QoS mechanisms must go beyond bandwidth reservation to accommodate each application’s specific requirements for latency, jitter and availability.
Ethernet QoS also must be able to provide variable bit rate (VBR), as well as Constant Bit-Rate (CBR), transport end-to-end. Those mechanisms are critical for enterprise applications such as a company-wide video multicast. QoS mechanisms help Ethernet services meet SLAs, which have become a competitive differentiator for enterprise data services.
A multiservice edge architecture is ideal for delivering Ethernet services with QoS that match or exceed that of incumbent technologies such as ATM. However, the Ethernet infrastructure also must replicate the existing services’ fault-tolerance and non-stop redundancy capabilities. These capabilities include sub-50-millisecond re-routing around failures and in-service equipment upgrades. The latter enables customers to receive in-service software upgrades.
With all traffic passing through the same edge device, the service provider has unified visibility of the network. This visibility affords them the ability to manage all Ethernet services, regardless of how they enter the router. This single-view visibility is critical because with multiple access protocols in use, service providers face the challenge of managing disparate provisioning systems. For example, it is inefficient to use one element management/network management system (EMS/NMS) to provision a Frame Relay leg of a service and a second EMS/NMS to provision an Ethernet leg.
That complexity and inefficiency highlights the value of a multiservice edge platform. It provides a single management view and controls to provision Ethernet services consistently, regardless of the underlying protocol. With the provisioning process unified at a layer independent of access and transport, the service provider now has a single view of the entire service, end to end. Eliminating multiple EMS/NMS systems helps make the delivery of Ethernet over anything cost-effective.

Flexibility for the future
For service providers, success in the Ethernet market involves developing a strategy that respects the past even as it embraces the future. Ethernet has a compelling value proposition for enterprises – high bandwidth at a reasonable price. However, not all companies can make a business case for abandoning their investments in infrastructure such as PBXs, ATM switches, Channel Service Units/Data Service Units (CSUs/DSUs) and Integrated Access Devices (IADs). Copper rather than fibre also serves many of those companies. Therefore, Ethernet services must respect the incumbent technologies in order to win business.
This mix of network infrastructure demonstrates the importance of an Ethernet migration strategy based on multiservice interworking. For enterprise customers, this approach reduces the cost of switching to Ethernet by leveraging incumbent infrastructure and transport technologies. For service providers, this approach protects existing revenues from ATM, Frame Relay and TDM.

Enterprise VoIP - Glittering prize?

While, for many enterprises, Voice over IP may seem to make sound financial sense, there are a number of issues which must be examined before taking the idea to the board, says Rick Marshall

More than a decade has elapsed since the IT and telecommunication industries heralded a new era of convergence. Few, at the time, had any real concept of what they really meant and that included the vendors themselves.
As the market grew to understand how to manage convergence between voice and data, it needed to find some way to make this happen. It also needed a compelling reason as to why business would ditch something it knows well and is proven technology in favour of the unknown.
The Internet Protocol (IP) dominates the way we move data in a digital world. As voice looked for a new way outside of analogue, it willingly embraced digital. For the operators, digital offered a more resilient network capable of carrying vast amounts of extra data. Networks were already going digital to deal with data, so simply adding voice made perfect sense.
Having resolved the ‘how’, the next issue is the ‘why’. Cost savings, lower costs, reduced costs are the mantras of the VoIP sales teams. On the face of it they have a very compelling case.
Whenever you make a call over a traditional Public Switched Telephone Networks (PSTN), you pay a charge. Even in the USA and some other countries that claim free local calls, these are no indefinite calls and there is an initial connection charge. Voice minutes have underpinned the financial stability of the telephony market for decades. Even though they are at an all time lowest cost, few companies have experienced lower call costs year on year.
The costs of telephony to a company are not just limited to call minutes. PBX equipment, telephones, fax machines, setting up call groups, writing software to integrate into applications such as call centres, voice mail, and follow-me services – are all examples of applications and costs associated with a corporate network. Some of these are real issues, such as software integration solutions that are hard to program, unreliable, difficult to keep synchronised with the user and when they don’t work, a support nightmare. VoIP has built itself a position by offering to eliminate or severely reduce all of these issues. The problem is, this is a clear case of overselling. VoIP is not the universal healing potion for voice that it has been said to be. So what is a real saving and what is mythology?
Call costs can be massively reduced, at least at the PSTN level. Reduced not eliminated. There is no guarantee that you will be able to only use IP end to end on the call. As soon as you touch a PSTN link, you will have some cost associated with the call. Some services such as Fax over IP (FoIP) are a long way behind VoIP and therefore cannot be counted as a real saving.
Replacing PBX equipment is only really going to occur when the equipment has already been amortised out. These were high value purchases that the organisation will want to wring every last penny from. Replacing early will need a compelling case. If the equipment is on lease or outsourced, then there may be significant charges associated with early replacement.
Handsets on the desktop can be a huge problem. VoIP handsets have dropped massively in price over the last year but they are still many times the cost of a standard desk telephone. If you think that plugging a headset into the soundcard of a PC or laptop is going to be acceptable to users, then you are going to be in for a rude awakening. Entry level prices for handsets can be around £80 rising to over £140 depending on the handset chosen. Try multiplying that by the number of users.
While some handsets draw little power and can be provided for via Power over Ethernet (PoE), the more fully featured handsets will need a power socket. The network administrators will already have a numbering plan for IP addresses. This plan is almost certainly under extreme stress as the IT department tries to cope with the influx of laptops, PDA and SmartPhones as well as other IP-enabled devices, being connected to the network. Adding roaming IP devices that require external IP addresses inside the corporate LAN may also cause management issues.
A number of vendors are using VoIP as a vehicle to persuade companies to move away from IPv4 to IPv6. This has an impact on all the equipment in the network, on management as well as on training for administrators and network staff. It’s a cost that is rarely ever mentioned in any discussions over cost of implementation.
Application integration is a big gain for IP telephony. With everything digital, developers can build new classes of enterprise messaging applications that combine voice and data seamlessly. Follow-me truly does follow the user. You have a single IP address for all your telephony. It could be assigned to the telephone on the desk beside you, your laptop, your PDA, even your SmartPhone. No matter where you are in the world, when you connect to the Internet, you are connected to your phone number.
But let’s not lose sight of the network. Greenfield sites are wonderful examples of what can be achieved. The network can be designed from the ground up with all the equipment and cabling capable of carrying much more traffic than it initially needs to. In the real world, the network might be capable of carrying the data but without sufficient metrics to prove that, it cannot be taken for granted.
Much of the data we move around corporate networks is not time sensitive. VoIP is. Get this wrong and users will not trust the service. When you pick up a PSTN handset today, you have a level of expectation that has been set by standards bodies and ensure no echo, no interference, just a clear channel where you can hear the caller and understand the message. Mobile telephony is different. While we all complain about mobility being used as an excuse for an inferior service it certainly doesn’t seem to have dampened our love affair with mobile telephony.
If the users get drop-out, interference, cross-talk and a poor experience, all the cost justifications in the world will be so much hot air. Telling the CEO that the savings are more important than his being able to talk to the corporate bankers over a reliable, quality service is a quick way to a new career.
If this sounds like you shouldn’t even be considering VoIP then stop. This is about setting expectations, identifying the challenges, not the problems. If you are going to implement VoIP then maybe the following points will help you establish what the real business benefits of enterprise voice over IP are:
1.  Test the network to ensure it can manage the additional data.
2.  Ensure that Quality of Service can be implemented and is sufficient to support VoIP.
3.  Assess the impact of roaming IP devices.
4.  Agree a Service Level Agreement with the business that provides clear targets for performance.
5.  Roll out slowly. A big bang will destabilise the network from IP address down to the architecture, switches and cabling.
6.  Be realistic about the costs of implementation and the savings. Return on Investment sounds good but make sure that you can deliver it before promising it.
7.  Look carefully at the new enterprise messaging applications you want to build and ensure that you factor in time for training developers so that they can deliver this.
8.  Create an ongoing set of metrics and a monitoring system to predict failure rather than react to it.
VoIP can be delivered to the Enterprise with remarkable results, but only if you go into it with realistic expectations and not just focussed on the hard sell.

Event preview - ECOC 2006

European Communications describes what will be on offer at this year’s fibre optic technology showcase

The European Conference on Optical Communication (ECOC) is broadening its technical content for 2006 as the reach of optical communications moves closer to the end user as part of the move to a truly converged world. In line with the conference scope, the ECOC exhibition will also address optical extension to the end user.
So, for the first time, there will be a significant presence to reflect the crucial and growing role that optical communications is playing in the Broadband and Access arenas and this has been welcomed by many of the leading companies taking part.
 “The converged world of communications is happening all around us and affecting all our lives every single day,” says Simon Kears, Nexus Media Marketing Manager. “Perhaps the most common example has been the spread of Broadband and it is the bandwidth carrying capability of optical communications that has made this revolution possible. It was therefore a natural progression for ECOC to begin to reflect how the industry’s commitment to research and constant new developments are continuing to play a fundamental role in how communications is changing for all of us – wherever we are on the planet.”
The extension of the ECOC 2006 programme will include various presentations from two new categories: ‘Backbone and metro core networks’ and ‘Broadband and access networks’. To date, the event organisers have received nearly 1000 proposals for technical papers for this year's event.
Falling under the wider topic of this year's conference – From Devices to Network Applications – papers include technology issues across the optics, broadband, FTTx and network solutions arenas. The show will also feature a market focus series of seminars, concentrating on the European Market, IPTV, metro and core network status, and FTTx in Europe.
Highlighting the event’s new and broader content, Kears comments:  “It is particularly pleasing to note that many of the submissions focus on broadband and access, reflecting the growing role that optics is playing in underpinning the world’s converged networks. This year there is an Asia trend, as nearly 20 per cent of the papers have come from Japan.”
ECOC will also, this year, launch an FTTx resource centre, where visitors will be able to view products, speak with experts and manufacturers, and browse through FTTx-related literature.
“FTTx is the key to providing businesses and homes with the technology of the future and will be a major focus at this year's ECOC,” notes Kears. “The FTTx resource centre will be a focal point for those manufacturing, integrating, installing and implementing FTTx, featuring JDSU, Fujikura Europe, and RSOFT.”
Jean-Luc Beylat, ECOC 2006 Conference Chair, adds: “The ECOC exhibition has been growing in status over the last few years and this new broader technical conference content is an exciting yet inevitable step. This new scope is the result of the tendency observed in the previous year’s submitted papers as well as in exhibitor requirements.”
This year’s event will also include a first ever free-of-charge two-day series of presentations on key technology trends and market shifts. Market Focus, featuring internationally renowned senior speakers from within the industry, will be located in the main exhibition hall.
More than 3,000 visitors and over 1,000 conference delegates visited the 2005 ECOC event at the Scottish Exhibition and Conference Centre in Glasgow. Already, ECOC 2006 is expecting to attract more than 1500 delegates to this year’s event and anticipates increases in exhibitor and visitor numbers.

Convergent online charging - The value of a unified view

With the majority of billing systems vendors now preaching the gospel of online convergent charging, European Communications looks at how it enables operators to become more competitive

As the telecoms industry continues to witness the ongoing expansion and globalisation of services and markets, not to mention the inexorable march towards the all-IP network, the imperative to create effective convergent online billing systems has never been stronger.  As Orga Systems Product Marketing Manager Billing, Mathias Liebe notes: “Today's billing deployments literally must enable operators to converge from current circuit-switched and IN-based services to 'combinational' and all-IP based approaches. 
“Future-proof billing solutions must have new qualities.  Otherwise, convergent approaches to rating and charging will not be able to cope with the scalability needed to charge for existing SS7-based services, as well as the flexibility to handle SIP-initiated sessions.”
Certainly, the vast majority of the billing systems vendors are banging the online convergent charging drum, not least because they recognise, as Nokia is keen to stress, that an operator's charging system is one of – if not the – single most important part of the cellular network and business operation. Unification and modernisation of the charging infrastructure is therefore vital.
Jorma Pohjalainen, Director, Core Networks Marketing and Sales, Nokia Networks, details the requirements of an effective converged charging solution:
“The key element is the ability to charge in real-time for all services: voice and data, fixed and mobile, access and content, prepaid and postpaid.
“The charging system must also support bundling of these services, since many subscribers view bundling across voice, messaging and data as their preferred method of purchasing operator services.”
He goes on to explain that online charging requires tight network integration for controlling access, and that the charging solution must also grant quotas – in other words, reserve money from the customer's account, before the customer can consume any service.
“Centralised rating and account management gives an operator a unified view of the entire subscriber base,” Pohjalainen says. “This enables the operator to introduce new services quickly and cost effectively. At the same time, centralised subscriber management is also one of the key factors in minimising operational costs.”

Innovative services
In a climate where getting innovative services to market faster than the competition – but still ensuring that profits are being made from them; and keeping users from churning, while also ensuring that services consumed are paid for, are all crucial, it's easy to see how any assistance would be welcomed by operators.
“Many operators compete in mature markets, characterised by few 'new' subscribers,” explains Giles Newcombe, Senior Director, International OEM Sales, Convergys. “Increasing ARPU rather than subscriber numbers is a significant driver of revenue growth, so operators have to tap into the potential of both prepaid and postpaid subscribers. A focus on optimising the value of existing customers requires a re-think of BSS requirements, and a shift from stovepipe legacy environments to convergent online charging systems that can accommodate both prepaid and postpaid accounts and offer the flexibility to combine a variety of charging methods.”
Nokia's Pohjalainen agrees that the ability to offer the full range of services to different types of customers – particularly prepaid – is among the primary drivers for operators to adopt convergent billing solutions.  Others include the fact that, clearly, since networks are converging, charging also needs to converge, and that because of increased competition, operators are looking for OPEX and CAPEX savings that a convergent charging solution can offer, while, at the same time, giving them tools to differentiate and compete.
Enumerating the advantages of convergent billing systems to operators, he notes that such systems offer the possibility of revenue sharing, and thus the ability to work with third party content providers, so extending the service offering. At the same time, customer retention is improved through the use of cross service bonus and loyalty programmes, while also providing the flexibility to support different business models and rating plans.

Holistic approach
Clearly, with a 'single view,' operators can adopt a holistic approach to customer management, facilitating more opportunities to cross-sell, up-sell, and increase ARPU and loyalty – particularly given that it is more cost-effective to hang on to existing customers, than to go out and find new ones. This approach enables operators to segment customers according to preferences, spending patterns, and identifiable behaviour that can be addressed with targeted services. In other words, the customer should no longer be viewed as simply a phone line or a SIM card, but as an individual whose spending and experience needs careful management.
Pohjalainen is keen to stress that the advantages of convergent billing are not confined to the operator, but equally benefits users.
“It enables customers to access all services, regardless of their payment method,” he explains, “while also providing the opportunity to establish hierarchical or shared accounts. So, for example, the user could have a family account where parents can control the usage of premium services by having those charged from a prepaid account, while normal voice connection is on a postpaid account.
“Bonus and loyalty programmes reward active users, while sponsoring can provide free access to certain services and/or content, and while these features undoubtedly enrich the user experience, they are clearly also a great antidote to churn.
“The online convergent billing system will also, of course, provide real time and flexible cost controls for all services,” he adds.
Siemens – who have, coincidentally, recently been developing an increasingly close relationship with Nokia – also sees the benefits for both operators and users, agreeing that the ability to handle both prepaid and postpaid transactions in real time is critical if customers and providers are to quickly check usage limits and status of account balances in real time. The capability allows customers to make informed decisions about their usage and expenditure, while enabling operators to better manage their risk and revenue exposure.
In the current, highly competitive marketplace, it is crucial for an operator to do as much as possible in order to stand out from the competition. Among the factors that facilitate positive visibility must be – inevitably – price, services and customer relationship, as well as the operator's own financial health.  Pohjalainen points out that each of these areas can be positively affected through the innovative use of charging and service control technology.                         

Consolidation v. innovation - The drive for change

The relationship between consolidation and innovation in the telecom sector is driven by IT convergence and technology empowered customers. Consolidation in search of synergies, cost savings and restructured offerings are driving change and possibility. Rick Ducey, David Gross and Chris Versace explain

Consolidation is moving at a fast clip. Bell Atlantic, NYNEX, GTE, AT&T, BellSouth, MCI, Pacific Telesis, Ameritech, and Southwestern Bell will be crammed into just two companies.  Alcatel, Lucent, Newbridge, DSC, Ascend, Cascade and potentially part of Nortel will have collapsed into one.  Nokia and Siemens have become Nokia Siemens Networks in order to reach both financial and technological scale and so, be able to compete with Ericsson but also fend off low cost competition from companies such as Huawei in China. Meanwhile Nokia has been slowly gobbling up small companies such as Loudeye, which will give Nokia a set of online music capabilities equivalent to that of Apple: devices (Nokia's new N-series handsets), a service, and licenses to a very large catalogue of music from all majors and many independents. A more recent acquisition by Nokia is the announced purchase of gate5 AG, which will give Nokia the ability to offer maps, routing and navigation applications for their mobile devices as well as offer potential tie-ups with some of gate5's existing customers (GPS navigation software is used by companies such as Siemens, Volkswagen, and DaimlerChrysler).
While on the face of it, recent rounds of consolidation may appear to result in potentially less competition and raise concerns about less market-based incentive to innovate, we would argue that there is a change afoot in these companies in response – to some degree – to competitive pressures, but the overriding factors include planned service offerings as, at long last, the convergence of transport technologies is happening. Case in point, T-Mobile is piloting a dual mode handset that allows for calls to be seamlessly transitioned from its cellular network to an in-home WiFi network.  Another example is the bundled service offerings that Verizon has through its Fios product offering, which is slated to be expanded further in 2007, once the company begins to include Verizon Wireless service in the bundle.
So the question to be asked is: Does all telecom consolidation mean the end of innovation? We say no.
Key to understanding this puzzle is seeing that the pressure on telcos to innovate will no longer come just from switch makers and telcos competing against one another in the marketplace, but rather from other market segments such as semiconductor firms, MVNOs and enterprise customers themselves. And not only will innovation continue, so will competition. Consolidation does not mean the end of competition, because telecom carriers are not the only companies building new networks.

Fixed-mobile convergence
There is an important, if desperate, strategy behind the moves such as those by Nokia/Siemens and Vodafone Group to converge fixed and wireless services as important precursors to developing new revenue streams. This type of restructuring creates new possibilities for new service offerings and revenue growth at a time when both are sorely needed. Of course, they are not alone in this endeavour, as we see Deutsche Telekom, France Télécom, Telefónica and Telecom Italia also organizing around new service offerings such as dual-mode mobile phones and WiFi phones with one number, to leverage their wired and wireless assets. These service offerings call for several new technologies, be they hardware (WiFi chips inside of handsets) or software (clients and user interfaces) as well as strategic relationships among vendors (with WiFi router companies like Netgear for example) and other solution companies (like Skype). And the MVNO segment will challenge the incumbents with their innovative approaches to brand marketing and added value.

Chip driven innovation
Telecommunications increasingly depends on the semiconductor industry to push it forward. This is because the phone companies are more exposed than ever to shifts in global and corporate equipment purchases.  The US RBOCs, for example, have deployed very little VDSL to date, but chipset supplier Ikanos has sold over 10 million ports just concentrating on the European and Asian markets.  These high shipping volumes overseas have cut port prices and, in turn, have made it much more cost effective for telcos to consider replacing some ADSL2+ cards just months after installing them.  Similar price reductions in routers and Ethernet switches have crossed over from the commercial market, which still accounts for well over half of the product sales for those segments. This means that the chip companies will continue to drive the pace and direction of innovation to a large extent in the telecommunication industry, regardless of the level of consolidation among service providers.
Historically, most data networking vendors, from Extreme to 3Com, have designed their own ASICs, and then built a box around that semiconductor architecture.  But over the last five years, while telecom companies have been getting bigger, transistors have been getting smaller. This has allowed the cost per bit of most equipment ports to fall, but it has also pushed up the cost to design a new custom chip from scratch, because so many more components have to be integrated onto each die. 
As chip pricing has fallen below certain levels, new applications have opened up. For example, Bluetooth in handsets would not have happened with $20 chipsets but when the chipset average selling price (ASP) passed below $5, the adoption rate in handsets, laptops and in other areas began to take off. We're seeing the same with WiFi chips and will likely see the same with mobile TV as well. Also, smaller sizes allows for smaller form factors or more functionality in 'current' form factors, or ones that are slightly smaller. This rings true for smartphones as well as mobile phones, but also MP3 players, laptops and more, as the size of chipsets, storage, batteries and the like have shrunk themselves and/or as companies have designed certain components amid more integrated packages.
While price/performance has continued to improve, it has done so with merchant silicon vendors shipping their products across multiple customers. With the fixed development costs of proprietary ASICs increasing, it has become very difficult for a start-up equipment vendor to reach break-even production volumes without being able to sell its designs to someone else. As a result, innovations that were once developed by box makers like Extreme, Juniper, and Bay Networks are now coming out of communication chip suppliers like Broadcom, Marvell, and Atheros. Thus, to see where markets are headed, it is critical to understand the technology roadmaps of semiconductor companies, as they are influential in setting the pace and direction of innovation.

Built to last ten minutes
Today's global market for hardware means that AT&T and Verizon are using many of the same products as France Télécom and Deutsche Telekom, and cannot dictate product requirements the way AT&T used to be able to do with Western Electric. The global hardware market has already taken a toll on the RBOCs' OSMINE process, which is increasingly becoming outdated and outmoded, because few PTTs force vendors to go through such a strenuous software integration process, and because element management systems have evolved to the point that little benefit is achieved by running everyone's systems through Telcordia before implementing them in a live network. 
With merchant silicon condensing upgrade cycles, global requirements taking many product development decisions out of the Bells' control, and more software-based enterprise equipment sneaking into telco networks, the major phone companies are increasingly expecting to toss out a lot of their hardware soon after it has been installed. The staid class 5 switch, ADM, and cross-connect markets were built on tightly integrated manufacturing processes, slow upgrade cycles, and limited competition among suppliers. And the pace of change in these hardware markets dictated RBOC purchasing procedures. 

MVNO consolidation and innovation
Successful new MVNOs, whatever their focus, will both accelerate the global phenomenon of the 'hyper-segmented market' and drive much-needed product and marketing innovation. In that regard, we view them as a good thing. Our concern, however, is that there is likely to be an eventual tear in the MVNO universe much the way a number of companies targeting the Internet in 2000 went bankrupt, were bought or simply vanished after the pop of that Internet bubble. With that said, we do not expect all of the MVNOs that are in the planning stages to launch, nor do we expect all of the launched MVNOs to survive.
Near term, we would expect MVNOs to foster greater churn in a battle for market share, particularly as they reduce pricing plans in order to stimulate demand. Consumers who are planning to switch mobile carriers in the future are primarily looking to improve two aspects of their mobile experience: price and service. Handset selection, customer service, data services, and unique content are all secondary considerations, even for those consumers who currently use advanced mobile features like data/content or messaging. This approach is likely to stimulate demand in niche markets and drive overall wireless consumption. Longer term, however, we would argue that wireless operators will fight these new players with more sophisticated marketing and targeted promotional offers. Our view is that eventually quality of service, price and scale will be the determining factors for successful wireless carriers, be they MVNOs or more traditional wireless network operators.
The experiences of MVNOs have underscored two things in particular. First, a virtual wireless venture can turn a healthy profit when planned, launched and operated effectively. Second, however, the downside risks of the MVNO marketplace are very real, and some companies may be underestimating the scope of the effort. The challenges can be overcome, but success involves skills, resources and operational systems that are not necessarily within the core competencies of some of the players getting into the virtual wireless game. For instance, looking at the UK, of the 15 or so MVNOs entering the market in 2006, at least 40 per cent will fail, and 10 per cent will seriously under perform against expectations.

Conclusion
At the end of the day, the pressure on telcos to innovate will no longer come from switch makers and telcos competing against one another in the marketplace but rather from other market segments, including enterprise users themselves. Consolidation does not mean the end of competition, because telecom carriers are not the only companies building new networks or offering services.
The telcos have invested capital on broadband and wireless, and launched new business products because DSLAM port prices have fallen 90 per cent since 2000, and because enterprise customers choose which hardware they want on their internal connections. If the phone companies do not provide the technology they demand, corporations will just keep their lucrative traffic on their own networks. This is why many new protocols, particularly Ethernet and IP, were deployed widely in enterprise networks before they were fully embraced by telcos.
