The Email Bag - UK and Sweden Updates

The UK: Broadband = TV?

We received an email from the UK in response to our article "Broadband in the UK - Focus on the TV" (BBHR Aug. 13, 2000). It verified our observation that most people in the UK associate "broadband" with the TV: "I met recently with an editor of a new homes publication who stated when asked what she thought BROADBAND was - isn't that something that comes through your TV?"

He viewed this as unsurprising given the large digital TV deployment in the UK and the associated strong marketing push on broadband TV coming from cable, satellite and digital terrestrial providers. Lower PC penetration and the late start on PC broadband access also play a big role. However, the situation seems likely to change with competitive broadband access enabled by local loop unbundling and wireless broadband spectrum becomeing available.

Our correspondent also pointed us to an interesting report by the U.K. Office of Telecommunications (Oftel) on "Consumers' use of Digital TV" ( ). From a survey done in 1Q2000, it indicates that although digital TV is installed in 1 in 5 UK homes, fewer than 1 in 5 of these make use of interactive services other than the electronic program guide (EPG).

It reports that "General lack of interest, or preference for using the Internet for these activities, were the main reasons for not using digital TV interactive services." It further reports that "Fewer than 1 in 3 consumers said they would be likely to use Internet or email via their digital TV, and was lower still amongst homes with PC Internet."

Its conclusion as to why more consumers are not using the interactive services was "Education and perhaps consumer confidence would appear to be the main issues here. Lack of interest in the services was the main reason for not using them..."

It could be. But it sounds to us like the industry has some work to do in figuring out what people really WANT to use, rather than what they need to convince them to use.

Sweden: If Broadband's There, Can Residential Gateways Be Far Behind?

Stefan Tordenmalm, a Bredbandsbolaget (B2) broadband customer from Sweden (see "Where Will the Broadband Revolution Start", BBHR May 4, 2000) writes that signs of residential gateways are showing up in Sweden.

"Hårdvarubolaget (Hardware company), is working on gateways. I saw pictures in an article. They looked like and were described as the type of gateway that is more like other home appliances than a PC. It contained several building blocks that you attach to a rack. There could be one TV block and one phone block for example. Well, it could be a good product but I would doubt it's anywhere near launch."

We tried to learn more about the company, but must admit our ignorance of Swedish got in the way. We'll report as we learn more. ( )

"End-to-End IP" -- How Will The ILECs Survive? (Part 1 of 2)

At the Fall Voice on the Net (VON) conference a few weeks ago (Sept. 12-14), we helped organize a session called "End-to-End IP - How Will We Get There?" We came away wondering whether and how the incumbent local exchange carriers (ILECs) will survive the transition to IP-based telephony.

We take it for granted that broadband access of one type or another (cable modems, DSL, direct fiber, satellite, etc.) will become widely available, and that many people will adopt broadband access and install in-home networks. PCs are usually the first end-user devices connected to the broadband network, but telephones won't be far behind. While customers may want to keep some of their existing phones, we think they'll be most interested in new phones with new features designed to work with the broadband network. Since IP is the common theme underlying all broadband access and in-home networks, it seems logical that we'll see consumer-oriented IP-enabled telephones.

We're already starting to see these "IP phones" -- many companies are working on them. They're designed to connect through in-home IP networks to IP-based broadband access networks -- and from there to IP phones in other people's houses. While at first they'll be more expensive than "plain black phones," they'll offer many features and services simply not possible today.

As with any new technology, early adopters will buy IP phones, volumes will increase, and eventually the price will drop so anyone can afford one. It's perfectly reasonable to think that ten years from now, many if not most homes will have at least one IP phone. Plain black phones will go the way of the black-and-white TV and record changer: they won't be thrown out, they just won't be used much.

To take advantage of their new features, IP phones need to connect to each other with "end-to-end IP," without going through today's public switched telephone network. Otherwise, the PSTN will dumb them down so they can't do anything more than a plain black phone. And going through the PSTN will perpetuate the pricing structure designed to recover the capital cost of obsolete central office switches, rather than the much lower cost of the global IP infrastructure.

It seems so obvious that IP phones will win. People may disagree on how long it will take, but we think almost everyone agrees that we'll eventually see "end-to-end IP telephony".

So we would have thought that most companies working on broadband voice for the home would be thinking about "end-to-end IP" and would be working hard to get there.

But that's not what we heard at the conference. While the cable industry seems to be heading in this direction, the telcos - especially the ILECs - aren't.

A recent book "The Innovator's Dilemma" explains why "disruptive technologies" cause strong market leaders to fail while making all the right decisions. "End-to-end IP" seems to place the ILECs in exactly the situation described in the book.

Jeff's Opening Remarks

In his opening remarks at the VON conference, Jeff Pulver observed that the "softswitch" vendors seemed to be preoccupied with recreating the 3000 features of existing central office switches, rather than creating new features and improving the end user experience. Jeff slides listed some enhancements he'd like to see:

  • presence capability for an always-on user

  • supports a variety of edge devices

  • capable of reaching a nomadic and mobile end user

  • multimedia support including Web and video

  • end user configurable

  • third party enhancement

  • handicap friendly and CALEA capable

  • adaptable and rapid management and provisioning

Listening to Jeff, it seemed to us that implementing these features is closely tied to the "end-to-end IP" issue. If a service provider wants to lay the groundwork for these new features, it should be aiming at end-to-end IP and pushing its vendors to provide solutions aimed at it. If a provider is focused on replicating all the existing features in today's network, it's easiest to work through the PSTN - which already has them all; but it delays the emergence of new capabilities.

The "End-to-End IP" Session

The "End-to-End IP" session, on the second day of the conference, was moderated by John Pickens of Com21, and included Martin Taylor of Coppercom, Noam Bardin of DeltaThree, and Don Stanwyck of IP Unity. We thought it was a terrific session and found it both stimulating and disturbing. The speakers all presented cogent arguments for their positions.

John's opening remarks framed the question clearly. He described two approaches to the "third-generation" telephone network. Both include "softswitches" (software controlled switches replacing the older switches).

In the "peer distributed" approach, the softswitches facilitate direct peer-to-peer IP communication between end-user phones. They're involved in setting up the call, but then get out of the way.

In the "hierarchical centralized" approach, softswitches take the place of the older switches, forcing all communications through a re-implementation of today's hierarchical structure. Two users with IP phones might be able to take full advantage of them if both were connected to the same cable system, but not if one wanted to talk to someone connected with DSL.

John summarized his views as follows "I believe that end-to-end VOIP has a very successful prognosis and we are beginning to see the early stages of its success - SIP phones, unified messaging, e-calling in browsers, and even softswitches. I do not believe however that henceforth the game is about reinventing the PSTN on Unix Servers and IP switches, but rather about discovering and enabling cool new voice-based applications which just happen to have gateways back into the PSTN and use the IP infrastructure for switching of the media stream. And the applications are beginning to be shipped today - thus the market is being enabled today (even leaving the legacy vendors behind)."

Martin Taylor said that Coppercom's customers aren't focused on end-to-end IP. Instead, they view voice over DSL (VoDSL) mostly as a one-for-one replacement for today's voice over twisted-pair copper.

Martin may have been deliberately provocative by calling his talk "End-to-End IP - Who Needs It?" but he pointed out that "almost no service providers are looking for a VoIP solution". Since most DSL systems include ATM for transport, and today's switches are all built to work with ATM, a "voice over ATM over DSL" solution fits right in to the existing network. Martin presented an excellent argument for ATM - proven technology, built-in quality of service, no privacy concerns, better efficiency, etc.

At the end, Martin pointed out the "culture clash" between the "IP culture" and the "telephony culture". While the "telephony culture" insists on charging a usage-sensitive price per minute to provide guaranteed service, the "IP culture" accepts "best effort" service in exchange for a flat-rate price. He concluded that "End-to-end IP won't happen unless there's a win/win for both users and service providers".

Noam Bardin made it clear that Deltathree would welcome a world moving toward end-to-end IP. As a provider investing heavily in IP telephony, Deltathree would like to carry the traffic between IP phones without paying hefty fees to the ILECs which originate and terminate today's calls.

Cable Operators Are Moving to Support IP Phones

Major cable operators have made a strong effort to roll out telephony over cable, and reported about 300,000 US subscribers at the end of 2Q2000. But none of this is IP telephony. The systems deployed to date are all based on using the cable plant as a one-for-one replacement for twisted-pair copper, and using the existing digital loop carrier (DLC) interfaces to connect to the PSTN. While many cable operators want to use end-to-end IP, they are well aware of the many issues, especially quality of service, which make it difficult to compete with the ILECs.

The North American cable operators (through their R&D arm, CableLabs) have been working with many vendors for several years to develop a full suite of protocols for IP telephony over cable. These protocols, called PacketCable, are designed for more than telephony, but IP telephony will be the first major application. Together with the updated DOCSIS 1.1 specification for cable modems, they provide a comprehensive approach for overcoming the quality-of-service issues in the "last mile" cable system to the user's home.

Prototype systems based on the draft Packetcable specifications have already been deployed by several cable operators. Systems that have passed CableLabs certification tests will almost certainly be deployed next year, first by cable operators new to cable telephony, and then by the large operators (especially AT&T and Cox) which have initially used circuit-switched telephony over cable.

The Packetcable specs are clearly designed to enable much richer features and applications when two IP phones talk to each other, and we expect that cable operators will over time start supporting IP phones for primary telephony. While operators will include interfaces to the existing black phones in the home and gateways to the PSTN for "off-network" calls, many operators believe that the new features of IP phones provide the path to winning market share in a competitive telephony market.

But nobody is working on the issue of connecting together IP phones in diverse broadband networks. On the current course, it looks like these new features will only work between IP phones connected to cable systems.

Look To The ILECs For POTS

A full picture of the "end-to-end IP" question requires looking beyond just cable and DSL. While these are the most visible broadband access technologies today in North America, other technologies are being deployed successfully in North America and other parts of the world: fixed wireless (Sprint in the US); direct fiber (B2 in Sweden); two-way satellite (Hughes and EchoStar/Gilat in the US).

DSL is the only technology that uses ATM as its native protocol; the others are all based on IP (a few propietary cable modem systems support ATM as well as IP). Thus is it likely that ATM-based broadband telephony will be isolated to the LECs. All the others will almost certainly implement IP-based broadband telephony -- and will seek to bypass the PSTN as IP phones move into homes.

It's perfectly understandable why the incumbent LECs would want to employ ATM and their existing circuit switches rather than directing telephone traffic to IP. They have enormous investments in their circuit-switched infrastructure and the people trained to operate it, and they're understandably reluctant to see it fade away any faster than necessary.

Most of the early customers for VoDSL are businesses - the best telephone customers, with much higher margins than residences. Businesses need lots of the CO-switch features Jeff was talking about - such as Centrex (CO-based PBX features) and direct inward dialing. The service providers already own switches that provide all of these features. So it makes lots of sense for the ILECs to use DSL as an economical alternative to twisted pair copper, rather than waiting for IP solutions with all the same features.

Some competitive LECs are focused on business markets and are also investing in circuit-switched technologies in order to get these same CO-switch features for their customers. Other CLECs will seek to compete in the residential market with new features and will embrace IP.

As customers adopt the new IP phones for their new features and applications, the ILECs will someday find themselves losing market share fast. They're likely to be isolated as the last major providers of circuit-switched "plain old telephone service".

How can they get out of this? See the next issue of BBHR for part 2...
