NTU 5030B small

Proscend 5099B Series 2-Wire/4-Wire Shdsl.bis NTU is a telecommunication product designed for carriers and SME users. The standalone modems offer a variety of choices for data interfaces to meet different connection needs. Proscend 5099B Series features E1/T1, Serial and Ethernet interfaces, allowing connection to different DTE types. When equipped with multiple interfaces, the standalone Shdsl.bis NTU combines user traffic over the Shdsl link. Available DTE combinations include E1+V.35/X.21, T1+V.35/X.21, E1+Ethernet, T1+Ethernet and V.35/X.21+Ethernet that can work simultaneously to share the DSL bandwidth.

The Shdsl.bis NTU supports two different connectors for G.703 E1 application that link to TDM service either by balanced 120Ω RJ45 jack or unbalanced 75Ω dual BNCs with bit rates from 64kbps to 2.048Mbps. For T1 connection, the Shdsl.bis NTU offers balanced 100Ω RJ45 Jack to carry bit rates from 64Kbps to 1.544Mbps.

As a Serial interface application, it links to high-speed TDM services by a DB25 interface, which can work as V.35/RS-530 or V.36/X.21 (factory setting) connection. The data rate of DB25 interface is up to 5.696Mbps for one pair of copper wires and 8.192Mbps for two pairs of copper wires.

For Ethernet interface application, the Shdsl.bis NTU supports 10/100Mbps auto-detected Fast Ethernet with a RJ45 connector, and provides customer premise with LAN to high-speed TDM services. The data rate of LAN interface is up to 5.696Mbps for one pair of copper wires and 8.192Mbps for two pairs of copper wires.

The Shdsl.bis NTU can be configured and managed via EOC, or menu-driven VT100 compatible Asynchronous Terminal Interface, either locally or remotely. The Shdsl.bis NTU provides the capability that identifies the maximum line rate supported by the copper loop. This powerful automatic configuration capability 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.
