	Virtually every SxS central office still operated by the BOC's has
had their connectors (both local and intertoll) modified with thermal
relays to provide for called-party disconnect after a nominal 30 seconds.
	This is also true of most SxS and X-Y central offices operated
by independent operating telephone companies.
	The lack of called-party release has been too much of a problem, so
modification or replacement of local and intertoll connectors to provide
a timed-release was a priority effort during the 50's and 60's.
