Abstract: The International Record Carriers have, for a number of years, provided a switched, overseas, voiceband data service called Datel. This report examines changes required in the Bell/Independent domestic MTS network to provide a more advanced form of interconnection for Datel than is presently available. The report examines Datel interconnection in terms of eight specific operational and technical areas: point of interconnection, numbering plan, signaling, operator procedures, customer billing, maintenance and testing, financial arrangements, and network planning. Three categories of solutions to the interconnection problem are discussed: short–, medium–, and long-term.

Keywords: Datel interconnection; international record carriers; switched voiceband data service
