Analysis to Trace of Common Channel Signaling (TUP)
Yuan Tianfu · Modern Electronic Technique · 2005
Common Channel signaling (CCS) has the advantage over Channel Associated signaling (CAS).It specially adapted to the develepment of future communication.Common Channel signaling NO.7 (CCS7) has been used widely in Public Switch Telphone Networt (PSTN),Integrated Server Digital Network (ISDN),Mobile communication Network,Intelligence Network (IN),Network's Operational Administrative and Maintenance.On the basis of description to the signaling message types and general signaling formation,we analyse the trace of Common Channel Signaling (TUP,Telphone User Part)between Digital Switch Programming Controlls(DSPC),the method will help improve the ability to the telcom equipment's maintenance.
