Connecting the SIC-1ADSL
2.12 SIC-1ADSL-I
2.12.1 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).
The card 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 card delivers these features:
z
Manual ADSL line activation and deactivation, providing a convenient fault
location means.
z
A G.992.1-compliant interface, auto-sensing.
z
Trellis coding on ADSL interfaces, enhancing the stability of ADSL connection.
Note:
For H3C MSR 20-40 and MSR 30/50 series routers, a SIC-1ADSL-I interface card can
only be installed in SLOT2 or SLOT4.
