LSSGR: Nail-up of Non-Switched Circuits on a Local Switch (FSD 20-16-0000)

Document Number GR-679
Issue Number 01
Issue Date Jun 2000
Replaces TR-TSY-000679 Issue01

    ABSTRACT: GR-679 replaces TR-TSY-000679, 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.

    In many applications, switched and nonswitched circuits are mixed on the same T-carrier facilities. When these facilities terminate
    directly on a Local Digital Switch (LDS), various measures must be taken to separate the traffic. A nail-up feature provides an option
    by which a private line special service or interoffice trunk uses a dedicated path through a switching machine from one transmission
    facility to another and is not subjected to normal call-processing functions. The path through the switching machine may be a more
    economical or convenient alternative than making the required trunk-to-trunk, trunk-to-line, or line-to-line connections by equipment
    external to the switch. This GR describes the view of Telcordia on generic requirements for a minimum feature set for nail-up.

    GR-679 replaced TR-TSY-000679 and TR-TSY-000360.

    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.
