The Supervisory Signal travels in the opposite direction of the

transmitted DWDM signal, and provides the following capabilities:

•

Node-to-node communication: SUPV communicates with the

SUPV controller core in other network elements via the OSC. An

example use of this flow is a CIT connection to a remote node

for sending TL1 commands and receiving responses. All such

inter-node communication flows through the SUPV controller

core before transmission on the OSC or private LAN.

Node-to-node communication is at 100Mbps–priority 2.

•

Orderwire communication: used to establish orderwire

connections between network elements. Orderwire

communication is at 5 Mbps–priority 1 (to minimize variable

delay).

The Supervisory Channel is not amplified and can run with the

OA/RP lasers off.

The Supervisory (SUPVY) Signal data rate is 149.76 Mb/s OC-3. Of

this bandwidth, 145 Mb/s payload capacity is available for the

Supervisory Data Link.

There is one SUPVY Signal for each Dense Wavelength Division

Multiplexing (DWDM) line. There are four ports per circuit pack and

two SUPVY Signals per optical line in a LambdaXtreme
