Validating the Call String This message structure is used to validate the call string:
STRUCT user^interface4 (*);
BEGIN
STRING base[ 0:-1 ]; ! Used with VARSTRING
INT message^type; ! 4 = Callstring validate
STRUCT callstring(VARSTRING); ! Pointer to call string
STRUCT linename(VARSTRING); ! Pointer to line name
STRUCT portname(VARSTRING); ! Pointer to X25AM SU name
STRUCT puname(VARSTRING); ! Pointer to PU name
STRING data[0:-1]; ! Call string, line name,
! X25AM SU name, and PU name
END;
Messages Returned by the
Validation Process
The VALIDATION process should return a message to SNAX/CM to state whether
the validation succeeds or fails. If SNAX/CM does not get this message within the
time frame defined by ENABLE command (TIMEOUT) or the default 60 seconds,
SNAX/CM stops processing this connection.
The messages returned by VALIDATION process are in the following structure.
STRUCT RESPONSE^INTERFACE;
BEGIN
INT RETURN^TYPE; ! 0 = successful
! 1 = reject XID string
! 2 = reject callstring
END;
