Troubleshooting
● Check the Cause Value Information Element (LOC). See Location Codes on page 130.
● Check Communication Manager administration (network generated the Cause Value).
- Dial-plan/Location: The home NPA is administered incorrectly, causing incorrect code
conversion.
- IXC: The IXC matching pattern is administered incorrectly or not at all on the dial-plan,
causing incorrect IXC manipulation.
- AAR/ARS digit conversion: The wrong digit string substitution is being made. The call is
being routed into the wrong network and over the wrong route pattern. Further
conversion is needed but the dial string is restricted from further conversion.
- AAR/ARS digit analysis: Call type is incorrect for the call being made specifying the
wrong type of number and/or number plan information, or it is preventing code
conversion from taking place. Call is being routed to the incorrect route pattern where the
incorrect digit manipulation and/or code conversion is taking place.
- ARS toll analysis: Toll/no toll classification is incorrect, causing incorrect code conversion
at the route pattern.
- Route pattern: Incorrect NPA is causing incorrect code conversion. If the Prefix mark
field has the wrong value, incorrect code conversion takes place. Toll list in combination
with prefix mark is causing incorrect code conversion to take place. The wrong number of
digits are deleted, or failed to strip IXC digits or international code digits. Inserted the
wrong digits IXC forcing the call to the wrong inter-exchange carrier, or stripped out a
user dialed IXC code. The incorrect service or feature is specified for the call being made
on a CBC trunk group preference. The Number format was changed to a format incorrect
for the call type.
● Check administration (Communication Manager generated the Cause Value).
- Trunk group: Incoming call handling table might cause Communication Manager to
delete or insert the wrong digits or number of digits to match the dial-plan.
Cause Value 29
[0x1D/0x9D] -
Facility rejected/
Special intercept announcement undefined code (NI-1: National ISDN 1)
The call could not be completed because the ISDN network does not support or is not
subscribed to the network service or feature requested for use by this call.
This Cause Value has end-to-end significance and should always be passed back through the
network to the user.
