A message sent in the forward direction that contains (a) address information, (b) the signaling information required to route and connect a call to the called line, (c) service-class information, (d) information relating to user and network facilities, and (e) call-originator identity or call-receiver identity.

In common-channel signaling, a procedure for ensuring that address messages are processed in the correct order when the order in which they are received is incorrect.

A part of an instruction that usually contains only an address or part of an address.

A prescribed structure of data used to represent the destination(s) of a block, message, packet, or other formalized data structure.

A Transmission Control Protocol/Internet Protocol (TCP/IP) protocol that dynamically binds a Network-Layer IP address to a Data-Link-Layer physical hardware address, e.g., Ethernet address.

Note: The identity of the message originator may also be included in the AIG. An address group is assigned to each AIG for use as an address designator.
