Description: Number of Calling Party Events transmitted from this interface. This counter monitors error events that occur due to the originating user doing something wrong. This counter is incremented when a RELEASE, RELEASE COMPLETE (only when not preceded by a RELEASE mesg for the same call), ADD PARTY REJECT, or STATUS message that contains one of the following cause code values is transmitted (Note: These cause values apply to both UNI3.0 and UNI3.1):

Cause Value Meaning 28 invalid number format (address incomplete) 43 access information discarded 57 bearer capability not authorized 65 bearer capability not implemented 73 unsupported combination of traffic parameters 78 AAL parameters cannot be supported (UNI3.1 only) 91 invalid transit network selection 93 AAL parameters cannot be supported (UNI3.0 only)

NOTE: For this counter, RELEASE COMPLETE messages that are a reply to a previous RELEASE message and contain the same cause value, are redundant (for counting purposes) and should not be counted.
