Compatible with both SDH and SONET networks, the two 2 port STM1/OC3 module accepts one or two STM1/OC3 signals, encapsulates them into Ethernet frames with or without robust Forward Error Correction (FEC) and transfers them to the MD8000 SW-CNT modules.

Additionally, the 2 port STM1 module accepts Ethernet packets transferred from the SW-CNT and provides one or two unique STM1/OC3 output signals.

Two completely independent bi-directional STM1/OC3 channels ensure that data on the individual ports is kept separate, permitting operation with total isolation.
Media Links Lossless Hitless fiber failover protection switching is also available for the transported STM1/OC3 signals.
