Abstract :
The operations administration maintenance and provisioning (OAM&P) functions provided by the American National Standards Institute (ANSI) for the following standards are described: T1.601, a 2B1Q-based transmission system at the network side of the NT1; T1.605, the United States version of the International Consultative Committee for Telephone and Telegraph (CCITT) Rec. I.430; and T1.216, for management of the ISDN basic rate physical layer. System life-cycle costs are discussed. These consist of the total of hardware cost, line engineering and installation cost, lifetime maintenance costs, and lifetime operations costs. A complete list of the OAM&P functions provided in the August 1990 draft proposed update to ANSI T1.601 is given together with their motivations. The other standards are only briefly considered. Field experience with ANSI-based maintenance is considered.<>
