Port
|
The port number.
|
Admin State
|
The port administration state. Choosing an administrative state from the drop-down list and clicking Apply changes the port's service state unless network conditions prevent the change. Admin states include:
IS-Puts the port in-service. The port service state changes to IS-NR.
OOS,DSBLD-Removes the port from service and disables it. The port service
state changes to OOS-MA,DSBLD.
OOS,MT-Removes the port from service for maintenance. The port service
state changes to OOS-MA,MT. For loopbacks, the OOS,MT admin state must
be initiated.
IS,AINS-Puts the port in automatic in-service. The port service state changes
to OOS-AU,AINS.

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.
|
Loopback Type
|
Allows you to provision a terminal or facility loopback, or clear an existing current loopback (none). Loopbacks can only be provisioned when the service state is OOS-MA,MT.
Note The ONS 15600 OC-192 card supports only payload loopbacks, the
ONS 15600 OC-48 card supports only facility loopbacks, and the ASAP
ports support both facility and terminal loopbacks.

Feac Loopback-Far-end alarm and control loopback; sets the DS-3 signal for
loopback.
Payload Loopback-Sets the DS1 payload for loopback.
Line Loopback-Sets the full DS1 signal for loopback.
