Document Number GR-693
Issue Number 01
Issue Date Jun 2000
Replaces TR-TSY-000693 Issue01

    ABSTRACT: GR-693 replaces TR-TSY-000693, Issue 1, 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.

    Customers in Equal Access End Offices (EAEOs) are generally presubscribed to one InterLATA (Local Access and Transport Area) Carrier
    (IC) or an International Carrier (INC). InterLATA calls from these customers are automatically routed to their presubscribed carrier
    unless the customer specifies a different carrier by dialing a 10XXX prefix. Certain calls, however, must carry the 10XXX prefix even
    though they are to be routed via the customer's presubscribed carrier. These include intraLATA calls and cut-through (10XXX+#). This
    Generic Requirements document (GR) describes the view of Telcordia on generic requirements for the Presubscription Indication feature,
    which provides for the transmission of an indication to an IC/INC of whether or not the calling station is presubscribed to that

    GR-693 replaced TR-TSY-000693 and TA-NWT-0001082.

    GR-666, GR-672, GR-674, GR-675, GR-677, GR-679, GR-690, GR-691, GR-692, GR-693, GR-695,
    GR-697, and GR-698, replaced TR-TSY-000530.
