Overseas Autovon Provision of Interim Capability for Precedence Network in-Dialing (PNID) to PABX's.

摘要

A method is described whereby,at selected PABX's (Private Automatic Branch Exchanges) in the overseas AUTOVON, a form of PNID service can be implemented with minimal equipment changes at the AUTOVON switches and at the PABX's,pending establishment of the universal PNID service offering by the USAF. The changes required at the switch and,with one exception,at the PABX are necessary for the future universal PNID service offering.
