type contained in the PAM e.g. IAM, REL) followed by the rest of the message
data which is encoded as it would appear in a message received from the
network.
‘Generic’ Charge message
The message data parameter may be used to convey the entire national

The message data parameter may be used by ISUP to signal the content of a
received unrecognized message to the user (depending on the setting of the
ISPGXOP_COMPAT circuit group option).
The first byte of the data field contains the message type.
