Introduction
The 1-port dual-pair G.SHDSL interface module (MIM-1SHL-4W) adopts trellis coded pulse amplitude
modulation (TCPAM) coding and provides symmetric rates up to 4.624 Mbps. The transmission rate of
the interface can automatically adapt to line distances and conditions.
Compared with ADSL, G.SHDSL allows farther transmission distance and thus has a wider application
scope. It is an alternative to E1/T1 line for high-speed data service access. However, as TCPAM uses
the band starting from 0 Hz for data transmission, G.SHDSL cannot share the same line with POTS or
ISDN like what ADSL has done.
The MIM-1SHL-4W delivers these features:
z
Supporting manual G.SHDSL line activation/deactivation and easy-to-use fault location tools.
z
Supporting G.991.2 interface standard and auto-sensing.
z
Allowing you to set the dual-pair G.SHDSL interface to operate in dual-pair or single-pair mode.

Interface rate
In single-pair mode, supports the sending and receiving independent
symmetric rates in the range from 192 kbps to 2312 kbps in steps of 8
kbps.
In dual-pair mode, supports the sending/receiving independent
symmetric rates in the range from 384 kbps to 4624 kbps in steps of 16
kbps.
