Independent LUs support the extended BIND, which contains information necessary to activate a session, to make use of features such as adaptive session pacing, and to identify a particular session. Extended BINDs always contain a fully qualified procedure-correlation identifier (a PCID qualified by the name and network identifier of the PCID generator). A BIND without this information is a nonextended BIND. Extended BINDs can contain network-qualified names if the subarea components in the session establishment path support them. An extended BIND is sent only if the boundary function (if applicable) and the destination LU support extended BIND.
