    ABSTRACT: Private Virtual Network (PVN) service uses the public switched networks to provide private network features and capabilities. It
    provides connections for customers within a Local Access and Transport Area (LATA) and, via interLATA Carriers (ICs), connections to
    other LATAs. Included in this feature are connections to and from physical private facilities. PVN offers business customers a
    service that is intended to replace and/or supplement current private network offerings. This service is designed to provide cost
    savings to customers while offering a simulated, dedicated network facility and improved network efficiencies for both network
    providers and users.

    This Technical Reference (TR) provides the view of Telcordia on generic requirements for the PVN services and includes requirements
    for both Service Switching Points (SSPs) and non-SSP switches interfacing with SSP switches.

    The requirements are intended primarily to provide PVN features; however, the capabilities specified in this document could possibly
    have applications for other services.

    Accounting (AMA) requirements of Section 3.5.8, "Billing and Comptroller." The changes made are technical, editorial, and reference
