M1-3 Overview
The Verilink M1-3 Time Division Multiplexer is designed to
aggregate 28 DS1 signals into a DS3 signal. This application
module operates with Verilink’s AS3000 product line.
The M1-3 application consists of the following components:
• M1-3 application module
• CIM 3113 Rear Connector Module
The M1-3 module is designed to operate with any of Verilink’s
AS3000 application modules. M1-3 control is provided by the SCM
controller module.
The M1-3 module manages and combines up to 28 T1 datastreams
(digitized voice, data, and video applications) into a T3 or
fractional T3 datastream. The DS3 port supports C-bit parity and
M1-3 M-frame structure for multiplexing DS1 to DS3.
NOTE: The IMUX and QUAD DATA application modules referred to in
this manual are due to release in Q3 1999.
Applications
The Verilink M1-3 Multiplexer is used to multiplex multiple T1s
from PBXs, routers, digital voice, and video applications into a T3
or fractional T3 service carrier. The far-end equipment can be one
of the following:
• Inverse multiplexers for high speed access and frame relay
networking (QUAD/IMUX).
• Another M1-3 with a full or fractional DS3 interface.
• Single T1/FT1 QUAD T1.
The M1-3 provides 28 synchronous DS1 payloads to/from the
AS3000 system midplane, providing a single DS3 network interface
supporting a line rate of up to 44.736 Mbit/s (
Figure 1-1 ).
