Introduction
1.1 Overview
MT1100A, MT1100A-DC, MT1100C, MT1101A, MT1101A-DC, MT1102A,
MT1102A-DC, MT1102C are interface converters. They convert unframed HDB3,
AMI or B8ZS data of ITU G.703 E1/T1 balanced or unbalanced interface into a
V.35 or RS-530 DTE interface.
The units operate at 1544 kbps or 2048 kbps. It extracts data and the clock from
the G.703 interface via a jitter attenuator to meet ITU G.823 requirements.
RIC-E1 acts as a line transceiver. It provides protection from over-voltage and
over-current stress caused by lightning, power crosses and other noise sources.
Versions
The following versions of the converters are available:
• MT1100A – standalone T1 to V.35 converter, AC power supply
•
MT1100A-DC – standalone T1 to V.35 converter, DC (-48 VDC) power supply
•
MT1100C – converter card for Rack Nest 2/14 modem nest, T1 to V.35
•
MT1102A – standalone T1 to RS-530 converter, AC power supply
•
MT1102A-DC – standalone T1 to RS-530 converter, DC (-48 VDC) power
supply
• MT1102C – converter card for Rack Nest 2/14 modem nest, T1 to RS-530
•
MT1101A – standalone E1 to V.35 converter, AC power supply
•
MT1101A-DC – standalone E1 to V.35 converter, DC (-48 VDC) power supply.
Application
Converters are typically used to connect between a G.703 network and a DTE.
The DTE can be a multiplexer, a bridge, a router etc.
Figure 1-1 illustrates a typical
application.
