Selective Call Rejection (SCR), a CLASS Feature, 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. To use the service, the customer can enter Directory Numbers (DNs) of
calls to be rejected into the system. Then, any call attempts to the customer
from these specified DNs should be prevented from terminating to the customer.
They should instead be connected to an announcement informing the caller that
his/her call is not presently being accepted by the called party.

GR-218-CORE defines the Telcordia view of generic requirements for SCR for
residential and small business, (non-Centrex) customers. Issue 2 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. In addition, a requirement has been added in support of AMA
generation for Screening List Editing (SLE) daily continuation records.

GR-218-CORE replaces TR-TSY-000218.

When using GR-218, you may need to refer to GR-220, and GR-1100. You
may also want to refer to GR-246 and/or GR-317.
