DSIC-1SHDSL-8W

Introduction

A 1-port 8-wire (4-pair) high-speed digital subscriber line interface module (DSIC-1SHDSL-8W) supports

symmetric link rate of up to 22.76 Mbps.

The G. SHDSL provides symmetric uplink and downlink and transmission rates of 192 kbps to 2312 kbps.

Developed from G. SHDSL, the G.SHDSL.BIS provides a higher-speed negotiation rate and supports

scalability of multi-pair wires in addition to the functions of the G. SHDSL.

The DSIC-1SHDSL-8W delivers these features:

• Communications in the ATM/EFM mode

• Manual/automatic switchover between the ATM and EFM mode

• Supporting using four/three/two/one pair(s) of wires.
