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

■Interface standards of G. DMT, G. Lite, and T1.413, auto-sensing.

■Trellis coding (except for G. Lite) on ADSL interfaces, enhancing the stability of ADSL connection.

n For H3C MSR 20-40 and MSR 30/50 series routers, a SIC-1ADSL interface card can only be installed in SLOT2 or SLOT4.
