TA NWT 000227 : ISSUE 4

Automatic Recall (AR) is a CLASS service that allows a customer to automatically callback that last incoming call. This TA-describes Bellcore's proposed view of generic requirements for a Stored Program-Controlled Switching System (SPCS) to provide this service for analog telephone lines. This TA-addresses changes from earlier versions of AR. Changes include requirements to support AR on an inter-LATA-basis, requirements to support AMA when AR is activated toward anonymous numbers, conditional requirements to support disallowing AR to anonymous numbers, and requirements to support disallowing AR to non-unique numbers. This TA also provides clarifications to previous requirements.
