    ABSTRACT: GR-218, LSSGR: CLASS Feature: Selective Call Rejection (FSD 01-02-0760), replaces Issue 1.

    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 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. In addition, a requirement has been added in support of AMA generation for Screening List Editing (SLE) daily continuation records.

    GR-218 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.
