VERIFYING THE BASE SYSTEM

WAN Lines Available for Use?

a.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.

b.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.

c.If the line was correctly attached, turn the system off, then on. If this fails to correct the problem, continue with the next step.

d.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.

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

(Layer 2 cannot be established, most likely due to an invalid configuration.)

a.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.

b.If the line was correctly attached, turn the system off, then on. If this fails to correct the problem, continue with the next step.

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

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

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

4.If a WAN line is still unavailable, issue the dr console command. If these two messages are displayed together, you may have a data link problem:

WAN card in slot <slot #> signals it is operational

Abnormal response rcvd: state=-1 msg=73 reason=6 cc state=-1

To correct the problem, try the following:

Check the configuration. Verify that all lines are configured with corresponding data links. If this is not the case, add data links to all configured lines.

5.If the above actions fail to correct problems, 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.

DEDICATED SERIAL CONNECTIONS

1.View the system messages for information on dedicated serial connections. At the administration console type:

dr <return>

2.The following messages may indicate a problem:

Error mapping adapter # into Host memory map

Type mismatch of configured & installed adapter #

Serial dedicated down: Slot #, Port #
