Introduction
1.1 Overview
General
MT1000A is a second-order multiplexer that combines four T1 (1.544 Mbps)
tributary data streams into a single fiber optic link.
The fiber optic interface provides a secure link in hazardous or hostile
environments, increases the maximum connection range, and achieves immunity
against electrical interference and protection against the harmful effects of ground
loops.
Features
The main features of the MT1000A multiplexer are:
•
MT1000A multiplexes four T1 channels over a single fiber optic link
•
A pair of MT1000A units offers simple connectivity for four T1 channels at
distances of up to 120 km (74.5 miles)
•
Redundant power supply
•
Optional second fiber optic link for automatic backup
•
Operates with multimode or single mode fiber; and single mode over single
fiber in the standalone version (WDM)
•
An optional second power supply for power redundancy and fail-safe
operation
•
Transmits each of the T1 channels independently, so that each T1 channel can
have it’s own clock source
•
To facilitate system diagnostics, MT1000A features LED status indicators, AIS
alarm generation, recognition and dry contact closure upon link failure.
•
Setup, control and diagnostics can be performed via ASCII terminal, SNMP
management station, or Ethernet link using Telnet or Web-based management
interface
