The denial event specified in the first trace of 1190 states the following. 1190 No circ/chan avail No circuit or channel available.
See Cause Value 34

Resource Unavailable Class Cause Values
Cause Value 34
[0x22/0xA2] -
No circuit/channel available/
Negative closed user group comparison (1TR6: AT&T ISDN Protocol)
Cause Value 34 indicates that he call cannot be completed because there is no appropriate
circuit/channel available to handle the call request, or congestion exists within the ISDN
network.
Communication Manager generates this Cause Value when a call is tandeming through
Communication Manager and the trunk group to be used for the outgoing leg is:
● In “all trunks busy” condition
● Otherwise unavailable for service
● Unreachable from the incoming trunk group due to Class of Restriction (COR), FRL,
trunk-to-trunk transfer restrictions, or disconnect supervision restrictions
Cause Value 34 (1TR6) indicates that the packet mode call was rejected because the user is
not a member of the remote end’s Closed User Group (CUG), which is a feature associated with
packet mode calls similar to X.25 connection made over the ISDN D-channel.
Communication Manager does not support packet mode sessions on D-channels, therefore this
is not applicable to Communication Manager.
This Cause Value has end-to-end significance and should always be passed back through the
network to the user.
