The aim of this document is to generically define the minimum requirements which, in the view of Bellcore, are necessary for the designing and the manufacturing of electronic equipment that are used in, or are attached to, the public information network and for which the design service life objective is 5 years maximum. The equipment include but is not limited to, switching, transport and loop equipment as well as to all other information network products attached to Local, Metropolitan and Area Networks such as communication and terminal servers, routers, gateways, bridges, modems, PCs, terminals, FAXs, hubs, adapters controllers, disk and tape drives, and other data equipment that are adjunct to the public information network.
