Abstract
This memo describes Session Id Registration (SESSID) that provides
the ability for one (listening) Application Server to indicate that a
session should be established with another (accepting) Application
Server for connection- and transaction-oriented messaging in the SS7
Signalling User Adaptation Layers [M3UA..TUA]. Extension parameters
and procedures are added by this memo in extension to those of the
User Adaptation layers to provide a closer model to that of the
XNS/XTI interfaces, where one interface may be designated as a
`listener' and another designated as an `acceptor'. This permits ISO

and TUA.
