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.
