    ABSTRACT: This document replaces TA-NWT-001242.

    This document contains the Telcordia view of generic requirements for a Selective Call Rejection feature operating through and
    Integrated Services Network (ISDN) Basic Rate Interface (BRI). This feature, called ISDN Selective Call Rejection (I-SCR), is a
    terminating call management feature that enables the user to signal a Stored Program Control Switching System (SPCS) to reject
    terminating call attempts to the user from a limited number of Calling Party Numbers (CPNs).

    The user can specify the Directory Numbers (DNs) of terminating calls that are to be rejected by the SPCS acting for the user.
    Unaccepted calls from these specified DNs are prevented from terminating to the I-SCR user.
