CSCO targeting ASND BY NAME! ASND must be putting the hurt on the gorilla. Does anybody know how important this alliance really is or is it cheerleading? #reply-6165149

By any measure, a coaxial cable can carry more data than a tw pair of copper can. The raw analog bandwidth is generally much higher for a single coax than it is for an unshielded- twisted pair. This is a fair basis for comparison because that's what is wired into homes at the present. All other things being equal, it is far more feasible to get a specified amount of content into a home over coax than over 1 or 2 twisted pair. As for the practical results, the TV cable has over 100 6MHz channels and each has a potential to carry between 5 and 56MBaud and preseent-day xDSL maxes out at 5-7MBaud total capacity. Most cable modem service are doing what they do at present with 1 TV channel for downlink and 1 unused channel below channel 2 for uplink. Beyond that and into the future, what gets realized depends on the modulation scheme, network topology, whether the TV is sent digital or analog and so on. Clearly, a single twisted pair is nearing technological exhaustion when one considers putting xDSL at 5-7MBaud over a twisted pair. On the other hand, a cable TV network is just starting to perform at that data rate and with more advanced modem chip sets, the assignment of more channels, the throughput goes up dramatically. What equalizes the situation is that whereas the cable TV co installs one coax, the phone co will install many tw pair along a route. But note that the phone Co has a lot of little bitty wires and splices to maintain and keep track of. Whose ahead? Can't say yet but the cable system more closely fits the need because the service has higher peak data rates and it is multiplexed.
