3.2.2.5 Cause

The cause element is used to indicate the reason for a particular event to have occurred and is coded as shown below.

The cause value is a single octet element if the extension bit (bit 8) is set to 0. If it is set to 1 then the cause value is a 2 octet field. If the value of the first octet of the cause field is 1XXX 0000 then the second octet is reserved for national applications (XXX will still indicate the class). 8 7 6 5 4 3 2 1 octet 1 octet 2 octet 3 (octet 4)

Element identifier Length 0/1 ext Cause Value

The length indicator is a binary representation of the length of the following element. Cause Value:

Class (000): Class (001): Class (010): Class (011): Class (100): Class (101): Class (110):

Normal event Normal event Resource unavailable

Service or option not available, but implemented

Service or option not implemented or currently disabled, i.e. not supported invalid message (eg parameter out of range) protocol error
