Issue 1 June 2005 155
- A call tandeming through Communication Manager on a non-ISDN trunk group
inter-working to an ISDN trunk group might have an incorrect bearer capability assigned
on the incoming trunk group. The BC and ITC fields on the incoming trunk group might
be set wrong.
Cause Value 58
[0x3A/0xBA] -
Bearer capability not presently available/
No user responding (1TR6: AT&T ISDN Protocol)
This Cause Value has end-to-end significance and should always be passed back through the
network to the user.
Cause Value 58 indicates that the call could not be completed because the user has requested
a bearer capability in the SETUP message which is implemented by the equipment generating
this Cause Value, but for which there are presently no resources available to be used to
complete the call.
Troubleshooting
Wait and try the call again later.
Cause Value 58 (1TR6) indicates that the remote device/endpoint/PBX did not respond with an
ALERTING/PROGRESS/CONNECT indication within the prescribed period of time allocated by
the expiry of the T303 or T310 timers in the Q.931 specification.
Troubleshooting
● Check the diagnostic information (DIAG) for the bearer capability attributes that are not
available. See Cause Values and their meanings/interpretations
on page 128.
● Check Communication Manager administration (network generated the Cause Value).
- Route pattern: An incorrect ITC and/or BCIE specified, these fields affect how the bearer
capability is encoded in the SETUP message.
- The ITC administered on the originating endpoint might be incorrect for this call, and/or
the speed options in the device itself might be incorrect for calls over these ISDN
facilities.
- Incorrect data speed option is set in the BRI device, causing a call from a BRI endpoint
tandeming through Communication Manager to create a SETUP message with the
wrong bearer capability.
- A call tandeming through Communication Manager ISDN trunk group to ISDN trunk
group might have a bearer capability that is not supported by the outgoing ISDN facilities
or network.
- A call tandeming through Communication Manager on a non-ISDN trunk group
inter-working to an ISDN trunk group might have an incorrect bearer capability assigned
on the incoming trunk group. The BC and ITC fields on the incoming trunk group might
be set wrong.
