AT&T's nascent plan to roll out high-speed Internet service over traditional phone lines is already hitting a speed bump: a little-noticed clause in a contract that AT&T signed earlier this year with two big cable companies could prohibit the telecommunications company from offering DSL in important parts of the country until June 2006.

The cold chill that has swept over tech companies during the past few months has hit DSL providers especially hard. In fact, even the big names like Rhythms, NorthPoint and Covad may not survive, unless they are gobbled up by bigger fish. (source: Upside) http://www.investorguide.com/cgi-bin/daily.cgi?03831 |

Wall Street played taps for NorthPoint Communications last week as the bankrupt DSL provider shut down its service. Now many are wondering if NorthPoint's grisly end will turn out to be the death knell for all independent DSL providers.

In Brief: - A study released this week by Harris Interactive showed that DSL subscriptions more than doubled between April 2000 and January 2001. Over the same period, subscriptions to cable modem services increased by just 10%, accounting for one out of every six new broadband subscribers. |

It's been a tough year for DSL companies, and no wonder: it seems easier to lay your own fiber network than to get DSL installed in your home. Still, it is possible for well-run companies to achieve success, even in difficult industries like broadband.

Despite a valiant effort, it's becoming increasingly apparent that DSL startups like Covad and Northpoint are doomed to fall before the big, old, slow phone companies. What happened? (source: The Standard) http://www.thestandard.com/article/display/0,1151,21043,00.html |

A new technological advance will allow fiber optic cables to transmit at 160 times their current rate. That innovation will make high-speed bandwidth much cheaper - a situation that's great for the consumer, but potential disaster for traditional telcoms.

While a DSL connection is desirable for its bandwidth, the trouble of getting one installed can be more than its worth. But now the government has mandated that local telephone companies share their wires with DSL providers – and the DSL nightmare may be soon over.

AOL and Gateway team up to provide DSL service to customers, but only in select areas, as they both refreshingly have decided not to downplay the seemingly universal difficulties with DSL installation. http://www.pcworld.com/pcwtoday/article/0,1510,14856,00.html |

A quote from a friend of mine. Granted he works for a Cable modem company... but i'm as confused as jhirsch based on what I heard from him and what I hear from smario and other DSL people. "here's what the phone company won't tell you: once you DSL "dedicated" line gets to the CO, it is combined with lots of other DSL lines in a device called a DSLAM (DSL Aggregator-Multiplexer). From there, there is a single line with all the DSL traffic from that central office that sends the data on up the chain, either to a larger CO or out to the Internet. The point is, you have a direct line to the CO, but after that the bandwidth is, in fact, shared. Moreover, the telephone company oversubscribes their DSL lines way more than the cable companies do." |

The idea behind DSL is that you get a CIR, or Committed Information Rate. If you have a CIR of 128K, you will never get below a speed of 128K. With cable access, you will never find a company who will promise you a minimum speed, only a potential maximum speed. Also, think of a normal phone line (which DSL goes over). You aren't sharing that phone line with anyone else - it goes directly into the local exchange, from their to your ISP, and from their into the Internet. Depending on your ISP, you may actually be connected to the backbone. But with cable, like everyone in your neighborhood, you are all connected from the same source, and the more that are on the network, the more the quality diminishes (unlike phone lines). They both go through modems, but the technology is different and such that a minimym bandwidth can be guaranteed for DSL, and not for cable. I don't how else to explain it, cause that's as much as I know, but I can say with certainty that DSL is a "dedicated" phone line with a minimum bandwidth, and cable is a "shared" network without a minimum. Hope this helps. |

I'm hearing a lot from both sides... the DSL camp and the cable camp. Here's the one MAJOR issue that I can't seem to get a straight answer on. the Cnet article Srini posted said this: "Cable has a very real problem with its bandwidth: The more subscribers who sign up for cable modem service, the slower that service becomes." Isn't that also a problem for DSL. DSL lines don't connect directly to the internet backbone do they? I'm assuming that just like cable there is some place where they all get funneled together and there are bandwidth issues. Also, will there be a bigger push toward cable through the roadrunner service with the recent AOL Time Warner merger? Thanks in advance, |

And CNET agrees. This is from their ten predictions for 2000: "The Prediction: xDSL will become the dominant high-speed communications protocol for the home, leaving cable modems as distant also-rans. The Challenges On the customer relations front, the phone companies will need to educate their people so that they can accurately represent the technology, and all xDSL companies must provide a rational consumer-based fee schedule. But these are minor hurdles, and since xDSL providers are still in early start-up mode, they have plenty of investment capital in the wings. What about the arguments for cable? Proponents point out that cable companies have an existing captive audience, and that they have the cabling already in place. They've also been working on cable modems for the last few years, and they are gaining ground over both standard and satellite alternatives. The Outcome |
