1 Introduction
1.1 Models
The G.SHDSL NTU Series offers three different interface models (E1, Data and Ethernet) for connecting
customers to high-speed TDM services .This series has three models:-
1.1.1 E1 interface model
Products Number: SHDTU03-E1-AD 2W
It offers two different ways have connected customers to high-speed TDM services with two G.703 E1
interfaces (Balance 120Ω RJ45 jack and Unbalance 75Ω dual BNCs). The G.703 interface can carry 64kbps
to 2.048Mbps.
1.1.2 Data (V.35) interface model
Products Number: SHDTU03-Data-AD 2W
It offers customers premises has high-speed TDM services with a DB25 interface. The industry standard
DB25 interface can be configured as a V.35/RS530 or V.36/X.21 connection. The DB25 connection can
transfers data up to 2.304Mbps.
1.1.3 Ethernet interface model
Products Number: SHDTU03-ET100-AD 2W
It offers customers premises has high-speed TDM services with a LAN interface. The industry standard LAN
interface can detect a 10Mbps or 100Mbps connection automatically.
The SHDSL TDM Series Modems can be configured and managed via EOC, or menu-driven VT100
compatible Asynchronous Terminal Interface, either locally or remotely.
The G.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.
