Proscend G.Shdsl.bis TDM total solution includes the rack with the line cards in the central side and network terminal units (NTUs) at customer premises. The rack solution is a cost-effective central unit for carriers to provide their customers with symmetric high-speed digital subscriber line (Shdsl.bis) services via consumer premise equipments (CPEs) with options of G.703 interface, multi-protocol serial DCE port or Ethernet port. Supported by ProEMS, a smart, comprehensive Element Management System that offers efficient control and management of Proscend's G.shdsl.bis TDM Rack system. This powerful EMS supports features of system management, network configuration, performance monitoring, fault detection & recovery and security control. It raises productivity, improves accuracy, simplifies training and reduces costs for network operation centers.

Proscend 3000 Series TDM Rack solution has powerful automatic configuration capability that makes installation and service provisioning simple and painless. Furthermore it provides flexible manually setting of the maximum NTU speed at different levels for different customer-tailored service offerings.

Proscend 5099B Series 2-Wire/4-Wire Shdsl.bis NTU offers a variety of choices for data interfaces to meet different connection needs. The standalone G.shdsl.bis modems feature E1/T1, V.35/X.21 and Ethernet interfaces, allowing connection to different DTE types. When equipped with multiple interfaces, the standalone 5099B Series NTU combines user traffic over the SHDSL link. Available DTE combinations include E1+Serial, T1+ Serial, E1+Ethernet, T1+Ethernet, Serial+Ethernet, E1+Serial+Ethernet and T1+Serial+Ethernet. Proscend 5099B Series can be configured and managed via EOC, or menu-driven VT100 compatible Asynchronous Terminal Interface, either locally or remotely.
