DSL - some notes on availability vs. cable modems: It would appear that the deployment of DSL would be easier than the deployment of cable modem service. After all, DSL works over copper wire, which is ubiquitous, while cable modem service requires bidirectional cable. Many cable systems were installed using unidirectional cable since the signal only had to travel one way - from the cable co to the consumer's TV sets. So in many cases cable firms have to go through the very expensive process of upgrading the lines. And they are doing it. At the end of 1998 there were approximately 700,000 cable modem users. In contrast there were about 39,000 DSL subscribers. As stated by the 1999 MultiMedia Telecommunications Market Review and Forecast: "This is despite the fact that for every one line configured for cable modem service, there are 20 telephone lines installed that can support asymmetric DSL (ADSL)." So the question is: What's holding up DSL? The answer seems to be the RBOCs (regional Bell operating co's). Some critics say that the RBOCs are smothering DSL the same way they avoided ISDN service. ISDN, which seems slow today, is much faster than regular 28k modems and has been available for some time but was priced too high for general consumer use. Many believe that ISDN was not pushed by the RBOCs because they were afraid of losing their lucrative T1 market. T1 lines are used by businesses that pay big fees. The fear is the same with DSL. Why should the RBOCs offer a similar service at a much lower price. In steps the CLECs: CLECs (competitive local exchange carriers) are allowed to offer DSL service and they do not have to worry about cannibalizing T1 revenues. Some prominent CLECs that serve the business market are COVD, RTHM and NPNT. Now, if an RBOC has to switch a customer from T1 service to DSL (or ISDN) they are going to see reduced profits, but if an RBOC loses a T1 customer because that customer switched to a DSL service offered by a CLEC, then the RBOC loses ALL its profits. So the RBOCs have two choices - they can hinder the CLECs (this they do) or they can roll out DSL themselves (which they are doing slooooowly). Of the 39,000 DSL subscriber mentioned above, perhaps 30,000 are customers of US West. Others like Bell Atlantic and BellSouth have done very little. Of course, besides worrying about the CLECs the RBOCs also have to worry about the cable guys. The question is: will they be motivated enough. If they are, DSL companies will profit and consumers will benefit. If not cable, and even satellite will likely take over. What we need to do is monitor deployment efforts. We need to find out if the RBOCs are just issuing press releases about intended DSL efforts or if they are aggressively signing up customers. One more twist: For the most part the purpose of DSL is to move data, and just about all the CLECs using DSL technology are providing data-only service. However, the latest innovation is to deliver voice over DSL (that's being called VoDSL). An article in the May 10 issue of Interactive Week began thus: "A Las Vegas-based competitive carrier last week became the first company to use Digital Subscriber Line technology to offer voice and data service to its customers." The company is MGCX, and they are currently targeting 5 markets. The June issue of Telecommunications calls voice traffic "DSL's New Killer App" and states that soon data voice and video will travel over a single copper pair. More to come. StockHawk
