¿µ¹®³»¿ë¿ä¾à This document describes V.52-User Adaptation Layer(V5UA). V5UA defines a mechanism for the backhauling of V5.2 message over IP using Stream Control Transmission Protocol(SCTP). This protocol may be used between a Signaling Gateway(SG) and a Media Gateway Controller(MGC) in case that the SG receives V5.2 signaling message over a standard V5.2 interface. So, MGC can control the analog telephone access, ISDN BRI/PRI access call over a V5.2 interface without the Local Exchange(LE) of the legacy PSTN. It is for migrating from the high-cost legacy circuit network to the IP-based packet network.
