I can understand why you so critical of Cable Modems now. MCI stands to be
left out of the Cable Modem arena. Although ISDN has been around for quite
sometime, it can be very expensive and undependable. I am not sure what you
mean by smaller backbone specifically related to CableModem networking, as
this would apply across the board to each and every example you listed. I
would say its irrelevant to the discussion. Further, the speed difference
between ISDN & a CM is @ 3 fold +. The equipment cost of ISDN equipment is
prohibitive, last time I checked. I guess what I am saying is adios
overpriced ISDN and hello CableModem. By the way, routers are old
technology as well. We still have some hanging around though.

Cable Modems are still considered a "New Idea" by corporate standards. (The
same goes for ADSL.) ISDN has been the choice for most home users since the
overall and initial cost are much less than the above. You can also push
the ISDN modems/routers up to 230K UP/DOWNLOAD without any problems..this
does depend on the site though. I've been running my old BitsurferPRO with
a TurboPort 920 card (16750UART CoProcessed Serial Card) at 230K for the
past 2 years without any problems..and this is also taking into
consideration that I run an NT Proxy Server at home for three different
workstations (all running DHCP with full access to the internet and email).
Cable modems can be setup to do this as well, but with some
difficulty...Home ADSL uses a static IP and does not allow Proxy Servers
since it communicates with ISP via IP Translation through the routers.
Pro's/Cons:
Cable Modems - Fast, but highly susceptible to "slowdowns" due to increased
client usage over smaller backbone. Also not available in most cities (CA is
very limited - Fremont was the test city)
ADSL - VERY Fast - 384K+, but you "pay to play". More speed, more money.
Initial equipment is around $700 for a good Router. (No extra phone lines
available)
ISDN - Fast and inexpensive alternative to 56K modems. Allows 2 phone lines
and also allows Incoming/Outgoing phone call while surfing.
US Robotics Courier V.90/Everything 56K = $250+ --- Max Speed = 53K (115.2K
if your lucky w/compression)
3COM Impact ISDN/TA = $350 --- Max Speed = 230K
Motorola BitsurferPro ISDN/TA = $280 (If you can still find one) --- Max
Speed = 230K
(Keep in mind that you can only reach 115.2K on a standard 16550 Serial
Port)
Southwestern Bell/PacBell and Earthlink have some of the most competitive
rates for ISDN around and monthly costs can be kept below $30.00 if you
don't "Live" in the internet.
2-Cents worth
