Pacific Bell Centrex IS DESCRIPTION ------------- Centrex is Pacific Bell's Central Office-based telephone service for businesses of all sizes. "Centrex IS" is Pacific Bell's business ISDN basic rate service that works with Pacific Bell Centrex. Centrex IS provides an all digital network that lets you use a single line for both voice and data communications at the same time. Withe Centrex IS, you can use existing phone lines instead of dedicated computer lines, plus reduce cabling and other communications costs. And because it's based on Pacific Bell's Central Office-based Centrex, Centrex IS gives you maximum flexibility for your communications planning. Centrex IS is based on ISDN -- Integrated Services Digital Network -- an international communications standard recognized world wide as the future of telecommunications. HOW IT WORKS ---------------- Pacific Bell owns and maintains the Centrex system. Which means you never have to worry about maintenance or repair for your network calling features.
