[From a cartoon. Publisher-Unknown Author-John Reed] Person #1: Boy! This Signaling System 7 - frequently known as common channel signaling 7 or CCITT #7, - debuted in 1980. Using up to 64 kbps links to interconnect stored program control switches, SS7 is the first truly digital signaling network. Its advent makes possible the use of special and general purpose computers and information data bases and brings a myriad of new network features and services to the public-switched network. Among SS7's key characteristics are true interactive out of band signaling, a feature rich protocol based on OSI standard mold, the capability to support a wide range of information services driven by network data bases and ISDN compatibility. Person #2: Yeah, but is it ground start or loop start?
