Abstract of the Disclosure A key telephone system is disclosed in which a direct station selection (DSS) arrangement reduces the number of operations required for the attendant to extend an incoming central office call to a station. The operation of one or more DSS keys on any of the attendant consoles in the key telephone system automatically places the calling central office line on hold and establishes a communication path through the DSS key contacts from the attendant to the selected station. DC bias on this communication path activates a loudspeaker and microphone arrangement in the selected station so the called party may converse with the attendant "hands-free". Addition- ally, the DSS arrangement provides the capability of utilizing any station in the key telephone system as the attendant position.
