Summary
Modem (56kbps) still popular and heavily used
- cheap, universal coverage
- preferred by “light” users (at SLAC about 1/3 use/user compared to ISDN)
ISDN still very popular, > 10 times xDSL&Cable
xDSL + Cable only small amount of use
- xDSL more popular in ESCC
Lot of uncertainty about xDSL, poor coverage
No site access routers for xDSL
