OSC


(ONS 15454 only) Use the OSC subtab to view, create, edit, and delete dense wavelength division multiplexing (DWDM) optical service channel (OSC) terminations and DWDM ring IDs. The optical service channel is a bidirectional channel connecting all nodes in a DWDM ring. The channel carries clock synchronization and orderwire channel communications for the DWDM network. It also provides transparent links between each node in the network. The OSC is an OC-3 formatted signal that uses the 1510-nm wavelength and does not affect client traffic. The DWDM ring ID is the unique identifier for ONS node DWDM rings.

Description

OSC Terminations

Displays the OSC terminations that have been created:

  • Port: Displays the slot and port where the OSC is provisioned.

  • Service State: Indicates the OSC port service state. Service states appear in the format: Primary State-Primary State Qualifier, Secondary State. Port service states include:

    • IS-NR-(In-Service and Normal) The port is fully operational and performing as provisioned.

    • OOS-AU,AINS-(Out-Of-Service and Autonomous, Automatic In-Service) The port is out-of-service, but traffic is carried. Alarm reporting is suppressed. The ONS node monitors the ports for an error-free signal. After an error-free signal is detected, the port stays in OOS-AU,AINS state for the duration of the soak period. After the soak period ends, the port service state changes to IS-NR.

    • OOS-MA,DSBLD-(Out-of-Service and Management, Disabled) The port is out-of-service and unable to carry traffic.

    • OOS-MA,MT-(Out-of-Service and Management, Maintenance) The port is out-of-service for maintenance. Alarm reporting is suppressed, but traffic is carried and loopbacks are allowed.

Create

Displays the Create OSC Termination dialog box to create a new OSC termination.

Delete

Deletes the OSC termination highlighted in the OSC Terminations list.

DWDM Ring ID

Displays DWDM ring information:

  • Ring ID: The DWDM ring ID.

  • West Direction: Displays the OSCM or OSC-CSM card used for the DWDM west line.

  • East Direction: Displays the OSCM or OSC-CSM card used for the DWDM east line.

Create

Displays the Create DWDM Ring dialog box to create a new DWDM ring.

Edit

Displays the Edit DWDM Ring dialog box to edit the highlighted DWDM ring.

Delete

Deletes the highlighted DWDM ring.

Help

Displays context-sensitive help.
