Generic Identifier Transport IE Used by Signalling
Generic Identifier Transport IE Used by Signalling
The generic identifier transport information element (IE) is used by signaling to carry an identifier
between two users.
Figure C-4 shows the format of the generic signaling IE.
Figure C-4 Generic Identifier Transport IE Used by Signalling
The generic identifier transport IE used by signaling has the following fields:
• Generic identifier transport information IE.
• Ext.
• Coding standard.
• Flag.
• Reserved.
• IE instruction action Indication.
• Length of generic indentifier transport IE.
• Identifier related standard/application—Each application requiring a different set or structure of
identifiers (coded in octet 6 and possibly in subsequent octet groups) should use a different value of
octet 5.
• Identifier type—This value is independent of the identifier related standard/application field,
octet 5. The maximum length is 20 octets.
• Identifier length—A binary number indicating the length in octets of the identifier code in the
subsequent octets of the octet group.
• Identifier value—Value of an identifier according to the recommendation or the standard identifier
in octet 5.
