Information technology — Telecommunications and information exchange between systems — Private Integrated Services Network — Architecture and Scenarios for Private Integrated Services Networking

Concerns with Private Integrated Service Networks (PISNs) comprising one or more than one PISN exchanges (PINX) interconnected by inter-PINX connections (IPCs). Specifies unter-PINX connections that are provided by intervening networks (IVNs), and the way in which these are handled by PINXs to provide a platform for inter-PINX communication. Identifies the standardization to inter-connect PINXs and general techniques, procedures and protocolls for all types of IVNs.
