DS1


Use the DS1 subtab to view DS3XM-6 or DS3XM-12 DS1 loopback information.

Port

The port number.

Derived State

The DS1 state is derived from the DS3 port state as well as the corresponding circuit state for the DS1.

Service State

An autonomously generated state that gives the overall condition of the port. 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-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.

  • 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.
