    ORDERING INFORMATION

    ABSTRACT: GR-312 provides a description of the characteristics and features needed for operation of a DS1 Interface Connector in a typical
    Regional Bell Operating Company/Information Distribution Company (RBOC/IDC) environment. This document does not specify a complete
    definition of a specific product design. The DS1 Interface Connector is intended for installation on the network side of the Network
    Interface (NI), the demarcation point between the Local Exchange Carrier (LEC) and Customer Installation (CI). The connector is
    intended for use on a digital transmission medium consisting of metallic cable pairs and provides a network/customer interface for
    services operating at the DS1 (1.544 Mbps) rate. The line code of the DS1 signal is bipolar (Alternate Mark Inversion (AMI)), except
    where intentional bipolar violations are introduced by B8ZS (Bipolar with 8-Zero Substitution).

    The criteria contained in this document represent minimum requirements. A RBOC/IDC, in its consideration of a particular DS1
    Interface Connector, may consider supplier claims for performance items not covered by criteria in this document or supplier claims
    that performance exceeds that required by the criteria as additions or modifications to the criteria.

    GR-312 replaces TR-TSY-000312, Issue 1, March 1988, 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.

    When using GR-312, you may need to refer to TR-NWT-000170, TR-TSY-000754,GR-54, GR-499, GR-57,
    SR-NWT-2759, GR-63, GR-357, GR-1, FR-64, GR-485, GR-1252, and SR-332.
