Line (slot #, port #) down
Action:
1. Verify that the line is correctly attached to the proper system resource and port.
2. If the line was correctly attached in action 1, try restarting the system.
3. If actions 1 and 2 fail to correct the problem, call your phone company (carrier) to check the
status of the line.
Problem:
The system does not display the WAN line availability messages. Instead, the system displays the
following message after the status console command is issued:
Out Svc 1 (slot #, port #)
This means that Layer 1 cannot be established, most likely due to WAN cabling problems.
Action:
1. If the system has been operational for longer than 2 minutes, verify that the line is correctly
attached to the proper system resource and port. If not, wait for 2 minutes and check again for
the WAN line availability messages.
2. If using a NT1 or CSU, examine the local and network lights of the NT1 or CSU. If the local light
is on, try another cable between the SmartSwitch Remote Access Module and the NT1 or CSU.
If the local light is not on, but the network error light is on, contact your line provider.
3. If the line was correctly attached in action 1, turn the system off, then on. If this fails to correct
the problem, continue with the next step.
4. Refer to the
PRI line provider. It is possible that there is a mismatch.
5. If the above actions fail to correct the problem, then call your phone company (carrier) to check
the status of the line. If it is determined that there is no problem with the line, contact Customer
Support.
