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.
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.

(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.
