ABSTRACT: This document describes the view of Telcordia on generic requirements for a Stored Program Control switching System (SPCS) to provide Ring Control (RC) service for analog telephone lines. Ring Control is an SPCS service that allows a customer to change the number of rings before Call Forwarding Don't Answer (CFDA) forwards a call.

This service will be available to customers with either rotary or Dual-Tone MultiFrequency (DTMT) equipped Customer Premises Equipment (CPE).
