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?
