Overview
Single-Channel STM-1/STS-3 Plesiochronous Level 3 Mapper
P3M1 (GC68301B-PI)
    The single channel plesiochronous level 3 mapper, P3M1, is designed for SONET/SDH add/drop multiplexer, terminal multiplexer, and unidirectional dual and single ring applications. Single channel plesiochronous signal is mapped to and from asynchronous E3 and DS3 signals accordingly. The interfaces to a multiple-segment byte-parallel SDH/SONET formatted bus are at STM-1/STS-3 byte rate of 19.44Mbyte/s.

Key Features
 
1.
P3M1 to multiplex DS3 (44.736Mbit/s) signals into to SONET STS-3/AU-3 via VC-3, or SDH STM-1/VC-4 via TUG-3
2.
P3M1 to multiplex E3 (34.368Mbit/s) signals to SDH STM-1/VC-4 via TUG-3, or SONET STS-3/AU-3 via VC-3
3.
Two independent Add and Drop Buses to support SONET/SDH Add-Drop Multiplexer applications
4.
External VCXO-free receive operation using build-in de-synchronizer and jitter attenuators

Product Applications
 
1.
SONET/SDH add/drop multiplexer
2.
SONET/SDH path termination multiplexer
3.
SONET/SDH cross connect system
4.
SONET/SDH test equipment
5.
Digital Loop Carrier System
