The OSC-CSM is used in unamplified nodes. This means that the booster amplifier with the OSC
wavelength combiner and separator is not required for OSC-CSM operation. The OSC-CSM can be
installed in Slots 1 to 6 and 12 to 17. The cross-connect cards enable functionality on the OC-N cards
and electrical cards.
The OSC-CSM supports the following features:
Optical combiner and separator module for multiplexing and demultiplexing the optical service
•
channel to or from the wavelength division multiplexing (WDM) signal
OC-3 formatted OSC
•
SDC forwarded to the TCC2 cards for processing
•
Distribution of the synchronous clock to all nodes in the ring
•
• 100BaseT FE UDC
Monitoring functions such as orderwire support
•
Optical safety: Signal loss detection and alarming, fast transmitted power shut down by means of an
•
optical 1x1 switch
• Optical safety remote interlock (OSRI), a feature capable of shutting down the optical output power
