Overview
The E1 Network Termination Unit (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).
