Abstract

An electronic switch telephone system comprising a current controlled bus switching device, a number of telephone subscriber line circuits connected to certain access points in the device and a number of link circuits and trunk circuits connected to other access points in the device, means comprising said junction circuits for accessing and extending trunk calls through said device, means operating on time distribution bases for assigning said access means to link and trunk call circuits for controlling the extension of switching circuits through said device and means responding to a condition of establishing a trunk connection to cause said trunk access access means to extend a trunk call through said device during the period of said distribution of time in which said junction call access means are assigned by said allocation means.
