SIC-1ADSL-I
Introduction
The 1-port ADSL over ISDN interface module (SIC-1ADSL-I) 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 use services such as high-speed data communication and video on demand (VoD).
The module transmits data in the high frequency band above 138 kHz. Therefore, it can provide
services on the same line without interfering with the ISDN service being provided on the same line.
It provides downlink rates in the range 32 kbps to 8 Mbps and uplink rates in the range 32 kbps to 1
Mbps.
The SIC-1ADSL-I interface module provides the following features:
• Manual ADSL line activation and deactivation, which provides a convenient method for fault
location.
• A G.992.1-compliant interface, auto-sensing.
• Trellis coding on ADSL interfaces, enhancing the stability of ADSL connection.
