Abstract
A telephone exchange transmits audible signals to a subscriber line to indicate exchange or network conditions. The audible signals to be transmitted to the subscriber line are selected from one or more available audible signal sources according to the contents of a store location for that subscriber line. Further store locations are provided for each subscriber line to enable selection of further audible signal sources dependent upon the condition. The subscriber may alter the contents of his or her store location by dialing a special code.
