146 Maintenance Procedures for Avaya Communication Manager 3.0, Media Gateways and Servers
Troubleshooting
● Check the diagnostic information (DIAG) for the facility identifier of the service that was
rejected. See Cause Values and their meanings/interpretations
on page 128.
● Check Communication Manager administration (network generated the Cause Value).
- Route pattern: The service or feature field contains an incorrect value for this route
preference. The ITC/BCIE fields might not indicate the correct information for a data call.
● Check administration (Communication Manager generated the Cause Value).
- Trunk group form: the Service type field might indicate a static service type when the
network is sending NSF information. Change the field to indicate CBC service.
Cause Value 30
[0x1E/0x9E] -
Response to STATUS_ENQUIRY
Special intercept announcement number unassigned (NI-1: National ISDN 1)
Cause Value 30 is included in a STATUS message when the STATUS message is generated
because a STATUS_ENQUIRY message was received. This is a normal event and does not
indicate a call-affecting problem. Communication Manager generates a call-state audit every
maintenance cycle that elicits this response from the remote end.
This Cause Value has local significance only. The ISDN network between the user and the
equipment generating the Cause Value might:
● Send no cause indication through the network
● Send a more generic Cause Value through the network
Cause Value 31
[0x1F/0x9F] -
Normal unspecified/
Special intercept announcement call blocked due to group restriction (NI-1: National
ISDN 1)
Cause Value 31 reports a normal event when no other cause in the normal class applies.
The ISDN network might substitute this Cause Value for other causes generated within the
network that do not have end-to-end significance.
For most Cause Values with only local significance on tandem calls, Communication Manager
maps Cause Values to Cause Value 31. See also Cause Value 02
on page 135.
Cause Value 31 can also be used as a return code on BSR polling attempts instead of Cause
Value 16 or Cause Value 17 depending on which Cause Value has less impact/interaction on
the intervening ISDN network.
