FIC-1SHL-4W
Introduction The 1-port dual-pair G.SHDSL interface card (FIC-1SHL-4W) provides a four-wire
G.SHDSL interface. It adopts 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 FIC-1SHL-4W has these features:
■ Supporting manual G.SHDSL line activation/deactivation and easy-to-use fault
location tools.
■ Supporting G.992.1 interface standard and auto-sensing.
■ Allowing you to set the dual-pair G.SHDSL interface to operate in dual-pair or
single-pair mode.
