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.
