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.

In addition to the G.703 DTE interface, the 336x E1 NTUs have one to four EIA 530A synchronous data ports that may be configured for rates of 64 kbps to 1984 kbps.

The 336x Series consists of a Model 3360 NTU (2-port), a Model 3364 NTU (4-port), and a Model 3365 NTU (1-port). Differences between these models are discussed where applicable throughout this guide.

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).
