Abstract

A telephone switching system (100), such as an ACD switching system in a call center, is used to broadcast information for users, such as displayable messages, to telecommunications terminals (110-112, 212), such as display telephones or data terminals, of a plurality of the users, such as call center agents, by means of non-call-associated display messages that are transmitted over the terminals' telephone lines (120-122), at the request of one of the users, such as the supervisor of the call center. The one of the users requests the broadcast either by depressing a predetermined button on their terminal accompanied by dialing a message identifier, or by dialing a feature access code and a message identifier, or by sending an ISDN 'userinfo' or DCP 'route text message' message that contains the information for users. The switching system uses either stored data or data contained in the request to determine the destinees of the information for users. The switching system then broadcasts the information in either an ISDN 'userinfo' or 'notify' message or a DCP 'text' message to the destinees' terminals for displaying to the users of those terminals.
