Check Communication Manager administration (network generated the Cause Value).

- Communication Manager sent the transit network identification in the NSF IE when the 

network expected it to be in the TNS IE. The protocol version on the DS1 form does not 
match the near-end ISDN network that is terminating the D-channel. Contact the ISDN 
network service provider and try to line up the protocols being used. NI-2 only supports 
the TNS IE, while custom protocol supports use of the NSF IE for this purpose.

[0x5F/0xDF] -
Invalid message, unspecified
This Cause Value indicates an invalid message event only when no other cause in the invalid 
message class applies.
Communication Manager does not originate this Cause Value for PRI. A BRI or Adjunct Switch 
Application Interface (ASAI) application might generate this Cause Value.
Troubleshooting
The diagnostic information (DIAG) of the Cause Value should contain, if implemented, the 
message type identifier of the invalid message. See 

[0x60/0xE0] -
Mandatory information element is missing
The equipment that sent this Cause Value Call Reference Value (CRV) received a message that 
did not contain a required Information Element for the message to be parsed and processed.
Depending on which message in the call establishment sequence is missing information, a 
message returned with this Cause Value might or might not indicate a problem establishing a 
call.
When the public network is screening for Calling Party Number (CPN), the fact that CPN is 
missing causes the network to return this Cause Value, but depending on optioning in the CO 
the call might still go through.
This Cause Value has local significance only. The ISDN network between the user and the 
equipment generating the Cause Value might:

●

Send no cause indication through the network

●

Send a more generic Cause Value through the network
