Overview

The E1 NTU acts as an interface between a High

bit-rate Digital Subscriber Line (HDSL) network and the
customer’s Data Terminal Equipment (DTE), converting
signals received from the DTE into the two binary, one
quaternary (2B1Q) signal format for transmission over the
HDSL network.

The E1 NTU’s G.703 DTE interface supports

2.048 Mbps (E1) data that is compatible with the signal
format of ITU Recommendation G.703 and the frame
structure of ITU Recommendation G.704.

The Model 3350 NTU is available in a compact

standalone case that can be mounted on a desktop or on a
shelf.

Features

The E1 NTU optimizes network performance with a

wide range of features such as the following:

•

Software configuration menu displayed via a liquid
crystal display (LCD) to permit quick and easy
operation, and elimination of complicated hardware
strapping.

•

Local or remote configuration and operation
flexibility.

•

Several loopback capabilities and test pattern
generators.

•

G.703 DTE capability.

•

Alarm message display/print capability.

•

Front panel emulation via Windows-based Front
Panel Emulation software.

•

Network management provided through
industry-standard Simple Network Management
Protocol (SNMP).
