TELECOMMUNICATION SYSTEM,IN PARTICULAR TELEPHONE SYSTEM

摘要

The system comprises a plurality of intercoupled subsystems (D5). Each sub-system (D5) comprises a control-unit (MCU) and at least one peripheral module (PM) to which communication lines can be connected. A problem involved is that when establishing a connection between two terminals (T) connected through the communication lines to the system a large number of data has frequently to be passed from and to the terminals. …The data management becomes more effective and more economic with the control-unit (MCU) of each subsystem (D5) comprises a list of numbers inside the system and that on the basis of a number of a desired destination connected to a communication line provided by a source connected to a communication line it is determined to which sub-system (D5) the destination is associated. When the destination sub-system is a system differing from the source sub-system, the required (signalling) information about the identity and characteristic of the source is transmitted to the control-unit (MCU) of the destination sub-system, whilst the connection is passed on to the destination sub-system. The control-unit of the destination sub-system then analyses said information and establishes the connection, as the case may be.
