    ORDERING INFORMATION

    ABSTRACT: GR-529 replaces TR-TSY-000529, Issue 2, but contains NO TECHNICAL CHANGES from that original document. It has been issued strictly to
    conform with the new Telcordia Technologies document format and GR process, and carries a new issue number and date.

    This Generic Requirements (GR) document presents the view of Telcordia on generic requirements for Basic 911 Emergency Service. The
    basic 911 emergency service feature provides a 3-digit universal telephone number (911) that gives the public direct access to an
    emergency service bureau, usually without charges to the calling subscriber. The emergency service is 1-way only, terminating at the
    service bureau. The emergency service bureau is usually located within a police department, although in some communities it is located
    in a fire department or in an independent agency serving a communications center. With appropriate Customer Premises Equipment (CPE) at
    the service bureau, and with the capabilities indicated in this document, connections are controlled at the service bureau regardless
    of the action of the calling party. In addition, customer options provide emergency ringback and visual calling party status monitoring
    capabilities.

    The call tracing feature allows identification of calling lines to determine the source of nuisance or threatening calls and to
    identify lines in emergency or demand situations. The document provides the following capabilities: calling line identification,
    in-progress call tracing, terminating call tracing, tandem call tracing, and outgoing call tracing.

    Group alerting service permits the controller (or alerting party) to dial a code to signal a preselected number of telephones
    simultaneously. After the predetermined signaling period, 1-way communication can be established from the controller to all members of
    the group that have responded to the signal.
