Table 7-6A-P-ABORT SERVICE PARAMETERS

A-P-ABORT Parameter Name Indication
provider reason P

The provider reason parameter shall be used to convey one of the following reasons:

a) reason-not-specified

b) unrecognized-pdu

c) unexpected-pdu

d) unexpected-session-service primitive

e) unrecognized-pdu parameter

f) unexpected-pdu parameter

g) invalid-pdu-parameter value

Note: In addition to these reasons, a locally defined list of reasons may be used to reflect errors that caused the abort and originated in the Session, Transport, Network, Data Link, and Physical layers. The generation and handling of such errors is internal to an implementation and, therefore, is outside the scope of this communications standard.
