ST112 Datasheet
The ST112's SONET capabilities include not only optical carrier generation, but also STS-3c/12c, DS3 and VT1.5 payload generation. Additional features include:
 
  • VT Channel Scan for testing VT mappings
  • Event sync (Opt. 07) provides output signals for deriving switch timing or propagation delay from alarm conditions
  • Byte synchronous payload mapping for next generation DLC testing
  • Full error and alarm generation

The ST112 Receiver analyzes the incoming optical signal and displays performance-monitoring information for the optical signal and payloads.
