Contains Bellcore's view of proposed generic requirements for a selective call acceptance feature operating through an Integrated Services Digital Network (ISDN) basic access interface. This feature called ISDN Selective Call Acceptance (I-SCA), is a terminating call management feature. It enables I-SCA users to instruct a stored program control system to attempt terminating call completing to the I-SCA user only from a limited number of calling directory numbers. Presents requirements for the following: feature operations; internal call processing controls; signalling message structure; administration operations; interactions; limitations and restrictions; timing and tolerances.
