ADC WorldDSL User Manual

WorldDSL™ G.S

Double Pair/Line Power
G.SHDSL for CO and Customer Premises

ADC’s WorldDSL G.S is a family of high-speed
G.shdsl access devices complying with the
ITU-T G.991.2 G.shdsl standard. These modems
are specifically designed for the diverse
telecommunication needs of global markets. Ideal
for telco and enterprise networks, WorldDSL G.S
products conform to international standards to
ensure compatibility, performance and safety
within your network environment.

The new G.shdsl modems are part of the broad
family of WorldDSL HDSL modems and share common chassis’, enclosures, management software
and accessories. They are fully G.shdsl compliant including 36/72 timeslot operation and all
required performance monitoring statistics. Both G.821 and G.826 statistics are provided for E1
ports giving users maximum flexibility. Each WorldDSL G.S modem is software-selectable as a
communication master or communication slave, so any two units can be used for a point-to-point
circuit. The modems are part of a fully managed system, interfacing with a VT100 compatible
terminal or a PC. The units can be managed via their local craft port or a central management card
installed in a CO shelf. ADC’s Stargazer, Windows or UNIX-based SNMP management software
can be used to provision the system, collect alarm and performance data, and conduct diagnostic
tests locally or from a remote management station. In any of these modes, the remote unit can be
programmed and managed through the CO, minimizing travel to the outdoor site.
