L M Ericsson Telefon AB has combined its MD110 PABX with the Broadband Interface Module system to create the MD110 Broadband Premises Network. This carries local and campus business communications traffic – speech, data or video, over a high speed fibre backbone network and links ISPBX Line Interface Modules with Broadband Modules. The latter support local networks, computer terminals, PABXs, video links and wide area networks in an integrated system, enabling users to implement transparent multi-protocol networks cost-effectively. The Line Modules are distributed switching units. Terminals that are connected to them are switched via the MD110 and other data traffic is directed via the Broadband Modules. All the modules are linked using a redundant fibre optic cable. The MD100 Broadband Premises Network provide a structured premises infrastructure for all types of traffic. When voice or data equipment is moved or changed in a building or campus site, this reduces costs. It is also claimed to provide a high degree of flexibility for connecting different types of data terminals and local networks. At the same time, overall network reliability is enhanced, says the company, because extensive redundancy is provided in the backbone network. The Premises Network forms one element of the Ericsson Business Network, which uses a combination of packet and circuit switching and bandwidth management to create a private digital network on which users are served by point-to-point and network integrated services. Any combination of fixed and mobile telephony and data communications can operate as a single entity over the Ericsson Business Network. No prices given.
