Denial Events
Cause Value 16
[0x10/0x90] -
Normal call clearing/
Requested facility not implemented (1TR6: AT&T ISDN Protocol)
Cause Value 16 indicates that the call was disconnected normally by either end hanging up.
Cause Value 16 (1TR6) indicates that the call could not be completed because the equipment
sending this Cause Value does not support the requested service, feature, or supplementary
service 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 facility identifier of the not implemented
service. See Cause Values and their meanings/interpretations on page 151.
Cause Value 17
● If the remote device terminated the connection unexpectedly, contact the person
responsible for the remote end to determine if there is a problem with the remote endpoint.
● For data bearer capability calls, if the connection has failed to establish, but the CONNECT
and CONNECT_ACK messages were exchanged before the DISCONNECT was
received, the handshake between the devices involved in the call might have failed due to:
- Option settings with the endpoint devices
- Bandwidth constriction issues on the B-Channels used by the two devices to make the
call
[0x11/0x91] -
User busy/
Requested facility not subscribed (1TR6: AT&T ISDN Protocol)
Cause Value 17 indicates that the endpoint called is unable to accept another call.
Cause Value 17 (1TR6) indicates that the call could not be completed because the user has not
subscribed to the service, feature, or supplementary service 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.
See also Cause Value 16 on page 164 and Cause Value 31 on page 169.
Troubleshooting
● Wait and try the call again later.
● If the user is supposed to have access to the service, feature, or supplementary service,
complete the ordering process with the ISDN service provider.
