158 Maintenance Procedures for Avaya Communication Manager 3.0, Media Gateways and Servers
Service or Option not Implemented Class Cause Values
Cause Value 65
[0x41/0xC1] Bearer capability not implemented
The call could not be completed because the equipment sending this Cause Value does not
support the bearer capability requested in the SETUP message.
This Cause Value has end-to-end significance and should always be passed back through the
network to the user.
Troubleshooting
The diagnostic information (DIAG) of the Cause Value should contain if implemented the bearer
capability attributes that are not implemented. See Cause Values and their meanings/
interpretations on page 128.
Cause Value 66
[0x42/0xC2] Channel type not implemented
The call could not be completed because the equipment sending this Cause Value does not
support the channel type requested in the SETUP message.
This Cause Value has end-to-end significance and should always be passed back through the
network to the user.
Troubleshooting
● Check the diagnostic information (DIAG) for the unsupported channel type. See Cause
Values and their meanings/interpretations on page 128.
● Check Communication Manager administration (network generated Cause Value):
- Communication Manager is attempting to make a wideband call over an interface to an
ISDN network that does not support wideband calls. Check the trunk group and routing
translations to be sure the attempted call has not inadvertently been routed to this
interface or was mis-classified as a wideband call.
● Communication Manager administration that can affect sending of this Cause Value:
- The network is supporting wideband calling and Communication Manager does not have
wideband support enabled on the Wideband Switching field on the
system-parameters customer-options screen
- Communication Manager does not have wideband support enabled on the Wideband
Support field on the appropriate trunk group
- The trunk group does not have the correct type(s) of wideband channels enabled
- Communication Manager does not have the right size wideband endpoint programmed.
