Abstract

   This document proposes the interfaces of a Signaling Gateway, which
   provides interworking between the Switched Circuit Network (SCN) and
   an IP network.  Since the Gateway is the central point of signaling
   information, not only does it provide transportation of signaling
   from one network to another, but it can also provide additional
   functions such as protocol translation, security screening, routing
   information, and seamless access to Intelligent Network (IN) services
   on both networks.

   The Transport Adapter Layer Interface (TALI) is the proposed
   interface, which provides TCAP (Transaction Capability Application
   Part), ISUP (ISDN User Part), and MTP (Mail Transport Protocol)
   messaging over TCP/IP.  In addition, TALI provides SCCP (Signalling
   Connection Control Part) Management (SCMG), MTP Primitives, dynamic
   registration of circuits, and routing of call control messages based
   on circuit location.
