54CHAPTER 2: SMART INTERFACE CARDS

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:

Manual ADSL line activation and deactivation, providing a convenient fault location means.

A G.992.1-compliant interface, auto-sensing.

Trellis coding on ADSL interfaces, enhancing the stability of ADSL connection.

n 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.
