Digital Switching, and How EPBXs are Used
Article Abstract:
Electronic manufacturers are emphasizing the role of digital electronic private branch exchange (EPBX) in office automation. Digital EPBX provides improved transmission quality, reduces the cost of hardware and saves space through the use of logic circuits, reduces the building costs of a network through the branching and insertion of multiplex digital signals, and integrates several communication services. It expands telephone services, provides packet exchange services, offers storage services for voice, facsimile and text, and permits conversion of media and protocols. Digital PBX is expected to play a key role in star LAN networks. Various diagrams illustrate the role of digital PBX.
