[sci.electronics] technical specification for CALLER ID.

jeng@ipanema..bellcore.com (Fureching Jeng) (01/19/90)

	Now some local phone companies offered a service 
"CALLER IDENTIFICATION" service. This service will let you know the caller
phone number before you answer it. You need buy a small box to disply the
caller phone number. Does anyone know any detail about the signalling of
CALLER ID service and where I can find the technical reference?
