A proposal for private T1 network management using DACS II in the central office.
01 January 1989
Bell Operating Company plans to provide virtual T1 services based on the deployment of central-office-based switching T1 multiplexers could undermine AT&T Network Systems sales of prominent transmission equipment, notably SLC systems, D channel banks, and DACS II. This memorandum briefly traces the history of network compatibility in T1 multiplexers, surveys the emergence of virtual T1 network services, and outlines the major elements of a proposal to complement DACS II with T1 resource management capabilities.
