USER’S GUIDE

386 CyberSWITCH

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 CyberSWITCH 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.

If using PRI, refer to the

Basic Information for Ordering PRI ISDN Lines

section found in the

Ordering ISDN Service chapter. Compare the parameters with those required by 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.

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 (2, 3, 4, or 5) (slot #, port #)

These mean that Layer 2 cannot be established, most likely due to an invalid configuration.

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 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.

3.

For the “Out Svc2 (slot # , port # )” message with a Basic Rate line, check configuration. “Auto
TEI” should be selected. Reconfigure if necessary.

4.

For the “Out Svc2 (slot # , port # )” message with a Primary Rate line, call your line provider and
have the data link restarted.

5.

For the “Out Svc3 (slot # , port # )” on an Auto TEI line, check configuration. Try reconfiguring
the line using non-auto TEI.
