摘要: The common channel signaling (CCS) system of the public switched telecommunication network involves digital call routing information that is communicated between switches and signal transfer points (STPs) CCS among STPs themselves. causes trunks connect them to be so interconnected as complete a connection calling party called party. are kept close practicable minimize length transmission links them. This results in proliferation less-than-optimally utilized STPs. Therefore, constituent parts STP geographically distributed over wide geographical area with higher-capacity STP, order realize substantial cost savings drastically reduce number individual extant thus complexity communication
