Any Raw IE can be inserted by the host for proprietary applications. Raw IEs will be inserted after any Formatted IEs (consult Q.931). The Q.931 recommendation specifies the format of the Raw IEs. IEs are always validated before issuing them in an ISDN message. The ISDN protocols ensure that the mandatory IEs are included with each ISDN message. See ITU-T Q.931 for a list of valid Raw IEs.
