Abstract
A communication system in which individual stations are connected to a control center by a transmission medium common to all of the stations to allow the transmission medium common to all of the stations to allow the transmission of messages in the form of digital signals between the control center and the individual stations. The length of a message transmitted to or from a specific station is determined by the information content of that message and is independent of the length of other messages to or from the same station or other stations. In particular, the invention relates to stations for use in such a system, and especially to means provided in each station to allow modular expansion units to be connected directly to the station or to another modular expansion unit that is connected, directly or indirectly, to the station.
