Introduction
SIC-1ADSL-I, the 1-port ADSL over ISDN interface card, uses the RJ-11 connector
for the WAN interface. It allows a LAN subscriber to connect to the DSLAM at the
central office over a regular analog subscriber line or telephone line. Thus, the
subscriber can access the ATM/IP backbone or the Internet to enjoy services such
as high-speed data communication and video on demand (VoD).
