Tektronix SC100 SONET Line Code Converter

SDH/SONET line code converter and timing source.

Three primary functions:
First, it converts received STS-1 (STM-0) AMI signals or STS-3 (STM-1) CMI signals into clock and data inputs.
Second, it converts data ECL outputs into STSX-1 or STSX-3 format signals.
Third, it generates a BITS (1.544MBps) or SETS (2.048MBps)clock signal to allow external reference synchronization to aid in SJ300 Jitter Measurements.
