CTC SHDTU03 E1

Thông tin chi tiết
The SHDSL NTU offers two different ways to connect customers to highspeed TDM services with two G.703 E1 interfaces (balance 120 Ohm RJ45 jack or unbalance 75 Ohm dual BNCs). The G.703 interface will carry data at N*64kbps rates (where n=1~32).

Features

The SHDSL NTU offers two different ways to connect customers to highspeed

TDM services with two G.703 E1 interfaces (balance 120 Ohm RJ45

jack or unbalance 75 Ohm dual BNCs). The G.703 interface will carry data

at N*64kbps rates (where n=1~32).

The SHDSL NTU can be configured and managed via EOC, or menu-driven

VT100 compatible Asynchronous Terminal Interface, either locally or

remotely.

The SHDSL NTU 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.
