Extension of an AIN/IN SSP

摘要

A telecommunication system includes an extension product (150) which provides for communication between devices which normally communicate using incompatible protocols, such as ISUP devices (158, 160) and AIN/IN devices (162, 164), using a programmable signaling interface (152). The programmable signaling interface (152) can be used as a basic call state model which is not dependent upon the proprietary architecture of a switching point. <IMAGE>
