GR 218 CORE : ISSUE 2

Defines generic requirements for Selective Call Rejection (SCR) for residential and small business, (non-Centrex) customers. SCR is a CLASS feature which is a revenue-producing service that enables telephone customers to instruct a Stored Program Controlled Switching System (SPCS) to reject call attempts from a limited number of calling parties. It adds Automatic Message Accounting (AMA) data generation requirements that are consistent with the Billing AMA Format (BAF) documented in the latest version of GR-1100-CORE.
