DESIGN OF A LARGE-CAPACITY SIGNALING TRANSFER POINT SYSTEM.

A common channel signaling (CCS) system was introduced into the telephone toll network in 1982. It has been applied to such new service networks as the mobile radio communication system. In order to expand new services and introduce NTT's Integrated Services Digital Network (ISDN), a signal transfer point (STP) system is needed for its high throughput and large link accommodation capabilities. This paper describes the hardware and software design concept for a large-capacity STP that will be above to handle 10,000 messages per second and provide 76 links.
