Introduction
The 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 provides the following features:
• Communications in the ATM/EFM mode.
• Manual and automatic switchover between the ATM and EFM mode.
• Supports using four, three, two, and one pair(s) of wires.
