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:
•
Supporting manual G.SHDSL line activation/deactivation and easy-to-use fault location tools
•
Supporting G.991.2 interface standard and autosensing
•
Allowing you to set the dual-pair G.SHDSL interface to operate in dual-pair or single-pair mode
