Briefly Noted: Updates, Observations and Trends

Each month, we collect miscellaneous happenings, studies, trends or observations you might have missed. This month's briefs focus on the demise of the payphone and the greening of broadband.

The Threatened Payphone

AT&T is discontinuing its payphone business which has been in place for 129 years. The steady drop in the number of US public payphones has been a result of the popularity of cell phones and the high cost of maintaining pay phones. In 1960 Bell Telephone had approximately one million payphones installed. That number swelled to about 2.6 million in 1998 and dropped back to one million in 2005. The count has been steadily declining since then. Of the major U.S. communications companies, Verizon is the sole surviving payphone provider.

Broadband: Color Me Green

There has been a flood of recent news about environmentally conscious efforts in the telecommunications/consumer electronics world. Although slow to join this move, an increasing number of US efforts have recently joined the broader movement.

  • Nokia Siemens Networks has joined the focus on "Green", announcing new energy-efficient products and setting the goal of connecting the world in a way that creates a net positive impact to the environment by maximizing the use of telecommunications.
  • In the UK, Green ISP advertises that since "powering your internet connection releases carbon emissions, we power our offices with Solar/PV and plant a tree for you when you sign up."
  • In Canada the Canarie Institute has created a presentation on the green benefits of information technology called "Saving the Planet At the Speed of Light".
  • A study from the American Consumer Institute, “Broadband Services: Economic and Environmental Benefits” shows that the use of broadband will lead to a reduction of as much as one billion tons of greenhouse gas emissions over 10 years.
  • Cox Communications has committed to conserving natural resources and protecting the environment. They have a commitment to reduce their total energy consumption and fleet emissions by 10 percent over the next decade and are implementing efforts involving efficient heating and cooling systems.
  • The Consumer Electronics Association (CEA) announced that the 2008 International CES is taking steps to “go green” by reducing its carbon footprint and with the use of sustainable and energy efficient practices.
  • One of the many pre-CES press invitations this year comes from GreenPlug, which will be demonstrating its digital solution for an environmentally-friendly universal power interface for electronics products. The solution uses a secure, digital protocol for real-time communication between devices that require power and their power sources.

TelcoTV 2007: Approaching The Tipping Point

Countries like France, Italy and Hong Kong have been offering telco subscription video services for years, while in the US until recently there has been far more talk than action. That has changed.

Several signposts indicate that telco-provided video services are near the tipping point in the US. One is how the discussion time is split between technology and services. A second is how many consumers are actually paying for the services. A third is how many markets the services are offered in. All have advanced a long way in the past year.


When we covered TelcoTV 2006 ( ) a year ago, several technology issues were front and center in the conference discussions. These included:

  • The lateness to market of highly integrated system-on-chip (SoC) chips--and therefore of the set-top boxes based on them;
  • The inability of service providers to isolate and fix the sources of poor video quality occurring between the video headend and the set top box in the home; and
  • Widespread questions and concerns about the scalability of systems, especially those used in AT&T's U-verse IPTV service.

This year, those issues appear to be well along toward resolution.

SoC-based set top boxes (especially those based on Sigma Designs chips) have stabilized, and high-volume chip makers like Broadcom are entering the IPTV SoC market. Second-generation IPTV has matured considerably with global deployments of millions of set top boxes. Improvements in efficiency of the video codecs used in these boxes have resulted in on-going reduction of the bit rate required to provide good quality high-definition video.

In 2006 it was difficult to find many vendors who recognized the critical importance of isolating the causes of quality-of-service problems. This year we visited with several vendors, including IneoQuest and Tektronix, which offer test systems to isolate traditional quality-of-service problems such as packet loss, packet delay, and jitter.

Other vendors, such as Symmetricom, are extending their test suites to include objective field measurements of so-called "Quality of Experience" (QoE), which extends traditional network-oriented QoS with additional measures such as channel change delay and audio/video synchronization. Symmetricom asserts that their metric reflects perceptual quality analysis in real-time, as experienced by end-users. Their products are based on the "Motion Picture Quality Metrics (MPQM) model adapted specifically for end-to-end video quality scoring", and is supposed to take into account both network and content impairments.

During 2006, we heard doubts about the scalability of AT&T's Microsoft IPTV system at every turn. This year, all the AT&T speakers, including Peter Hill, AT&T’s VP of Video and Converged Services, and Paul Whitehead, Executive Director-Project Management, went out of their way to assert that their 126,000 deployed U-verse customers and continuing expansion demonstrated that the Microsoft system will scale.

AT&T's U-verse customers are spread thinly across 33 markets. While their total numbers may indicate scalability of provisioning and installation, we don't believe they yet show the ability of a single system to operate effectively at peak load times. Several AT&T speakers said that they were continuing to make progress in expanding the number of users supported by each server.

Our discussions with knowledgeable sources convinced us that several new techniques promise further improvement. In particular, we came away from our discussion with Alcatel-Lucent convinced that bringing its century of experience in “traffic engineering” to bear will make a major contribution to Microsoft's server scalability.


Compared with last year, this year's show had significantly more air-time devoted to describing services -- both those available today and some of those anticipated in the future.


AT&T's speakers emphasized how the services provided to its U-verse customers already have features not available from cable:

  • the ability to record up to four shows at once
  • built in picture-in-picture
  • interactive personalized information via the "U-bar," allowing customers to access customized stock, weather, sports and traffic information on their TVs, while "squeezing back" the TV picture to provide room for the customer requested information.

AT&T's Peter Hill gave a well-received talk on "The Future of Telco TV". Starting with existing U-verse applications, he moved quickly to show forward-looking work by AT&T Labs on new converged services concepts. He described and demonstrated fourteen service concepts illustrated with screen shots.

One example was "Family Finder" which lets you select a member of your family. It then shows on a map the location of the cell phone of the person you are looking for. You can zoom in and out of that location by using Google maps and GPS, see a history of where he or she has been, and click once to call that person.

Another interesting application was "Video Share Mode" which allows customers to share video between cell phones. One person can see what the other is pointing their cameraphone at. The video share can be transferred and displayed on the TV or on the Web, so the person at receiving end doesn’t need a video share-capable phone.

AT&T's plans to use such services to distinguish themselves from the incumbent cable and satellite providers.


Verizon chose a different approach for its video services. Viewing any DSL approach (even VDSL2 used by AT&T) as a stop-gap, Verizon invested heavily in a PON-based fiber-to-the-premises (FTTP) infrastructure. Rather than using IPTV, it launched its FiOS Video service with conventional RF video while waiting for IPTV to mature.

We missed the talk by Tushar Saxena, Verizon's Director Home Networking Technologies, but caught up through her slides. The talk was focused on the importance Verizon places on remote management of customer home networks for all their TV, PC and telephone services in the home. A key emphasis is that Remote Management via TR-069 "enables Verizon to take the 'IT' out of customer’s homes". Verizon's Broadband Home Router acts as the home gateway and router for all data services. [See the MoCA article below for more on Verizon home networking.]

Other Verizon talks focused on additional aspects of their services, including widgets (on-demand access to real-time local weather and traffic info, without interrupting the program they are watching), media manager and multi-room DVR. The focus was more on services than the underlying technology.

The Numbers: Consumers and Markets

At the end of 3Q07, AT&T had 126,000 U-verse IPTV customers (up from 51,000 3 months earlier) and was launched in 33 markets. AT&T says it is installing new U-verse customers at the rate of almost 10,000 per week. During AT&T's recent Analysts Day presentations, the company said it expected to have 1 million U-verse customers by the end of 2008. John Stankey, AT&T's group president of telecom operations, indicated that their installation rate will accelerate to reach 40,000 installations per week by the end of 2008. By the end of 2008, AT&T expects to have its IPTV service available to 17 million homes and is targeting 30 million homes passed by its fiber-to-the-node (FTTN) rollout by 2010.

Verizon, which launched about one year earlier than AT&T, added 202,000 new subscribers to its FiOS TV service in the third quarter, giving it a total of 717,000 subscribers at the end of 3Q07. It is now adding customers at the rate of 3,200 per day. FiOS TV is now offered in 13 states; the availability doubled in 2007 to cover 15% of households in the Verizon serving area. The service was available for sale to 4.7 million premises, and penetration averaged 15.2 percent across all markets.

Open Issues


Standards continues to be a key open issue for the telco TV industry. The opening session of the conference--"TelcoTV Standards Roundtable: The Road to Seamless Services"--focused on IPTV standards for Telcos and the consumer electronics industry. An alphabet soup of organizations was represented on the panel, including the Alliance for Telecommunications Industry Solutions IPTV Interoperability Forum (ATIS IIF), Consumer Electronics Association (CEA), the Digital Living Network Alliance (DLNA), the DSL Forum, and the International Telecommunications Union Focus Group IPTV, (ITU-T, FG-IPTV). While there appear to be some attempts at coordination and collaboration, the panel acknowledged that there are numerous overlaps and gaps. It is far from clear to what extent these organizations will collaborate with each other rather than fighting for turf.

Management of the home network highlighted differences between the groups. The telecom service providers view management of home networks as crucial to their successful provision of end-to-end services, and want to see their management protocols embedded in consumer devices. The Consumer Electronics industry disagrees, saying that adding these protocols is in conflict with the economics of consumer electronics--they can't afford to increase the component, software and power budget to support telco network management. Nobody represented the view of the consumers themselves, who might be unhappy about accepting decisions about their home networks imposed from the outside.

Broadband Video

Another issue which sits in the background is how non-traditional broadband video content is going to fit into the video service mix. There is more than enough evidence to suggest that broadband video (from Joost, NeuLion, Vongo, YouTube and Veoh, to name just a few) is a reality. What is not at all clear is the formula for making it a commercial success. Ad supported models and "direct to TV" products from Sony and Hewlett Packard are a couple of the mechanisms that are being tried. Incumbent video providers like Comcast as well as new entrants like Verizon are experimenting with where and how these types of video fit in their offerings. Such a direction will be a departure from previous "walled garden" approaches.

Although not a major topic at TelcoTV, it was raised by a number of speakers. The increasing availability of content, the increasing speed of broadband connections and the efforts to simplify the way content gets to viewing devices are all indicative that this trend will continue. Multiple methods and lots of experimentation are the order of the day. We expect a mix of business models--user-paid, ad-supported, licensing agreements--will continue to play out over the next few years.

A Deep Gulp - MoCA Technology Conference 2007

The folks at the Multimedia over Coax Alliance (MoCA) invited us to participate in an analyst panel in their first annual conference ( ) in Austin Texas last month. After some hesitation--we felt "conferenced out" after attending four conferences in as many months--Dave decided to go and was glad he did. It was a great update on current MoCA technology and applications, and a good view into the future.

We have been following MoCA from its inception, and started talking with Entropic Communications, its founding technology company, even earlier. We've long believed that coaxial cable could provide the best physical platform for "no new wires" networking. Unlike any other existing wiring, coax is designed for the very high bandwidth needed to carry multichannel video. Because it is shielded, coax is largely free from noise. Even when fully occupied by a full video lineup, coax has lots of unused bandwidth suitable for data networking.

The main drawback of coaxial cable is that there are comparatively few coax outlets in the home. Thus we have long believed in a home networking approach which uses coax both to connect the TV sets--which require the most bandwidth and are highly sensitive to noise--and to provide a "backbone" network for the whole home. Wi-Fi could then be used to reach mobile devices and other devices that aren't close to coax outlets.

Verizon's Use oF MoCA in FiOS

For all its promise, MoCA has still not been deployed very widely. Its primary application to date has been for telephone companies providing video services to the home. Its largest deployment has been by Verizon for its FiOS service.

Verizon's CTO and Senior VP-Technology Mark Wegleitner delivered a keynote talk at the conference. One of his slides illustrated how Verizon uses MoCA over the existing coaxial cable, with two MoCA channels operating on different frequencies.

One MoCA channel (the "WAN" channel) links the Optical Network Terminal (ONT) mounted outside the home with a Broadband Home Router (BHR) inside. The second "LAN" channel connects the BHR with video set top boxes. PCs connect to the BHR with Wi-Fi or optional "MoCA dongles". Having two separate MoCA channels isolates the WAN channel used for Verizon services from the LAN channel which can be used for additional consumer applications.

Wegleitner said Verizon is using MOCA as part of "The Verizon Managed Home", managing all video, voice and data communications for PCs and TVs through the BHR. He said more than 700,000 FiOS subscribers are using MoCA today, with more than 3 million MoCA nodes installed in FiOS homes.

To match the speed of FiOS, Verizon required at least 100 Mbps. The WAN and LAN channels each operate at more than 100 Mbps over the same coax infrastructure.

Shortly before the conference MoCA announced that the latest MoCA chips support 175 Mbps throughput. At the end of his talk, Wegleitner emphasized "the need for additional bandwidth in the home", saying "the next generation MoCA must support ~400 Mbps of actual throughput in less than two years" with "a roadmap to 1 Gbps within 4 years".

MoCA Technology

A session on MoCA protocols provided more details on MoCA than we've seen before. The recently announced addition of parameterized quality of service (PQoS) makes it possible to mix multiple streams and adjudicate their priorities if they cannot all operate simultaneously within the available bandwidth. This is already incorporated in MoCA 1.1, the basis of the latest chips.

The active participation of speakers from Broadcom and Conexant--in addition to Entropic Communications, the original developer of the technology--made it clear that major semiconductor manufacturers see a bright future in networking over coax. Broadcom and Conexant are on the MoCA board as promoter members, with Intel and Texas Instruments participating as contributing members.

Extending MoCA to Retail

Until now, MoCA has been deployed only by video service providers. Without MoCA-based products available for consumer networking, other technologies--especially Wi-Fi and various forms of powerline networking--occupy all the space on retailer's shelves.

"Extending MoCA to retail" was a recurring topic at the conference. Several sessions covered the potential for retail products. Keynote presentations by speakers from Intel, Scientific-Atlanta/Cisco, and Motorola touched on consumer applications. Speakers from Radio Shack, D-Link and Actiontec participated in a panel discussion on retail applications.

In the product demonstration area, D-Link showed the use of MoCA to transfer video from a networked attached storage (NAS) device to a high-definition screen. Scientific-Atlanta and Linksys (both now divisions of Cisco) showed a Linksys home router equipped with a DLNA media server working over MoCA with an S-A set top box equipped with a DLNA player. None of these are as yet on the market as retail products, but the implication was that they were close.

Consumers are starting to use home networking to move video from consumer-owned PCs and DVRs to flat-screen TVs throughout the home--both video recorded on the PC hard drive and streaming video from the Internet. MoCA is moving to retail just as video is moving rapidly to high definition and consumers are installing flat-screen HD sets in large numbers.

This move to retail appears to pose some problems for video service providers, who will need to grapple with several issues:

  • How will video service providers handle multiple high-definition video streams over the same network infrastructure? When network capacity is limited, which streams get the highest priority and the best video quality, and which get degraded quality? Which devices control priorities and admission control? Can the consumer participate in this decision?
  • What support will video service providers offer to customers who install their own MoCA equipment? For example, will Verizon include consumer-installed devices in its "Verizon Managed Home" or will it be restricted to Verizon-provided devices?
  • Do video service providers enable PC-to-TV and Internet TV applications, or leave these to the retail market?

We came away from the conference looking forward to seeing some of these retail devices at CES next month, and playing with MoCA-based networking in our own home and condos.

For More Information

  • We first wrote about Entropic Communications four years ago in Whole Home Networking over Coax -- An Interview with Entropic ( ) (BBHR 11/16/2003) and mentioned the formation of MoCA a few months later.
  • We've also covered the HomePNA Alliance. Originally created for networking over existing telephone lines, HomePNA was extended nearly four years ago to add networking over coax -- see HomePNA -- Don't Count It Out ( ) (BBHR 2/17/2004). AT&T is using HomePNA for its U-verse IPTV deployment.

Network Problem Solving with HomePlug

At the MoCA Technology Conference--see the previous article ( )--Dave participated in an analyst panel "From the Press Box". Kurt Scherf of Parks Associates moderated the panel, and asked the panelists to describe how they use home networking in their own homes. Each of the panelists--the others were Rick Merritt of EE Times and Jeff Baumgartner of Cable Digital News--told a similar story about how they had used HomePlug to solve a networking problem-typically creating a broadband connection from a PC in one room to another somewhere else in the house.

Dave described how even though we strung half a mile of Category 5 cabling through the walls of our house in the summer of 1996, we had failed to provide an Ethernet outlet in our dining room, where we house our main audio system. We used HomePlug to provide the network connection for an AudioTron Digital Music Player to access all our CDs stored on a hard drive. We wrote about this application nearly five years ago in HomePlug - Problem Solving and More Test Results ( ) (BBHR 1/21/2003).

Soon after the MoCA conference, we closed on the purchase of a second condo on Sanibel Island. As we had done with our first condo ( ), we moved quickly to install a cable modem and set up a PC for our rental guests. But we found that the cable modem would not connect to the cable network properly in the master bedroom where we wanted to install the PC.

We traced the cable wiring, and found that the cable connection came into the guest bedroom and went through two splitters before it reached the master bedroom. The two splitters dropped the cable signal to a level too low for the cable modem. We tried connecting the cable modem to the first splitter in the guest bedroom and it worked fine.

So we ran out and bought a kit with two Linksys PLE200 PowerLine AV Ethernet Adapters based on HomePlug AV chips. We installed the Linksys configuration software on one of our laptop PCs and quickly configured both adapters with a secure password to reduce the risk of someone in the condo complex spying on our network. We connected the output of the cable modem to one AV adapter in the guest bedroom, and connected our VPN gateway/router to the other AV adapter in the master bedroom.

The new PC was online immediately, as were our two laptop PCs connected to the router with Wi-Fi. We quickly established a VPN connection to our home network to access our files at home and maintain the new PC remotely.

It felt like the cable modem and the gateway were connected with an Ethernet cable. HomePlug solves another networking problem! Our first renters are arriving for the holiday week, so we'll soon see how well it works over time.

Upcoming Conferences

2008 International CES

Most of us have some signpost that tells us that the New Year is on its way. For us, the sure sign is the meeting invitations we start receiving for the January Consumer Electronics Show. After the hundredth one arrives in our inboxes we start to wish we were past this yearly landmark. The PR folks struggle to make their invitations stand out from the crowd. This year’s winner was clearly the one with the subject line: “Attack of the CES PR People, Run for Your Life”.

This year’s show takes place January 7-10 in Las Vegas, NV, USA. For any of you who have somehow missed this extravaganza, be forewarned. You’ll need to pack your best walking shoes and a large dose of good humor to withstand the long taxi lines and crowded halls. Despite all this, we wouldn’t miss it for the world. We hope to see you there.
