Shdsl. Bis Ntu Modem

• The Proscend 5000B series SHDSL.bis NTU is a telecommunication product for carriers or SME users.  In one device, it offers three DTE interfaces (E1, V.35 and Ethernet), which can work simultaneously to share the DSL bandwidth.  This user-configurable interface during the installation provides a flexible design for various connections.
  
  The SHDSL.bis NTU supports two different connectors on G.703 E1 application, which provide the connection to TDM services (either balanced 120� RJ45 jack or unbalanced 75� dual BNCs) by the bit rate from 64kbps to 2.048Mbps.

As a V.35 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 within one pair copper wires and 8.192Mbps within two pairs copper wires.  The SHDSL.bis NTU provides the 10/100Mbps autodetected Fast Ethernet by a RJ45 connector, which offers customer premise from LAN to high-speed TDM services.

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.
