5000 G.SHDSL NTU (E1)

The Proscend 5000, SHDSL NTU E1 interface AC input with LCD display, offers two different ways to connect customers to high-speed TDM services with two G.703 E1 interfaces (balance 120O RJ45 jack and unbalance 75O dual BNCs). The G.703 interface will carry 64kbps to 2.048Mbps.

The SHDSL NTU can be configured and managed via EOC, or menu-driven VT100 compatible Asynchronous Terminal Interface, either locally or remotely.

Proscend 5000 is equipped with an auto rate 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. Further flexibility is provided in the ability to manually set the maximum NTU speed at different levels for different customer-tailored service offerings.
