Local area network for use in office communications and a circuit arrangement therefor
First Claim
1. A local area network comprising at least one network node and a number of work stations for use in an environment with different communication requirements using Asynchronous Transfer Mode technology, characterized in that the respective network node (1) and/or each work station (2, 21, 22, 23, 24, 25) is assigned a unit (8) which performs switching technology functions, that can be accessed by wired terminals (4, 5, 6) and cordless terminals (7) via respective interface circuits (41, 51, 61, 71), and that connections are established as needed for the exchange of informationfrom a cordless terminal (7) to a wired terminal (4, 5, 6), via the unit (8) which performs switching technology functions, and is assigned to the respective network node (1) and/or the work station,from a wired terminal (4, 5, 6) to a cordless terminal (7), via the unit (8) which performs switching technology functions, and is assigned to the respective network node (1) and/or the work station,between one of the wired or cordless terminals assigned to a first work station, via the unit (8) which performs switching technology functions and is assigned to the first work station, and via the network node (1), as well as via a unit (8) which performs switching technology functions and is assigned to another work station, and a wired or cordless terminal assigned to this other work station, andbetween a wired or cordless terminal assigned to a first work station, via the unit (8) which performs switching technology functions and is assigned to the network node (1), as well as via another work station to a wired or cordless terminal assigned to that work station.

Abstract
LAN'"'"'s are customarily used for pure data communication. Voice communication via a LAN is only possible with the constraint of other subscribers being subjected to long waiting periods during the relatively long occupation time. The present LAN expands the functionality of work stations connected to the LAN, by using ATM technology to meet the communication requirements of an office environment. A network node or a conventional work station (3) is expanded by means of a unit which performs switching technology functions, so that terminals of the most different types (4, 5, 6, 7) can access the LAN via interface circuits (41, 51, 61, 71), resulting in a private network with distributed telecommunication installations. In this way, real-time connections with different bandwidth requirements, such as for example video conferences and pure voice transmission, are made possible. The thus expanded ATM-LAN is suitable for all types of communications taking place in an office.
