Transaction Network, Telephones, and Terminals: Maintenance and Administration

Transaction Network Service and the equipment and operational programs developed to implement the message switch communications system which provides the service are described in Refs. 1 to 4. The service has been designed to operate in the existing operating telephone company environment, using existing facilities, craft forces, and administrative and maintenance organizations. To meet the objectives of a highly reliable, available, and maintainable total service, procedures have been developed which fit the service to its operating environment. This paper describes those maintenance and administrative capabilities and procedures.
