KEY TELEPHONE SYSTEM INTERCOM ARRANGEMENT |
摘要 |
<p>A key telephone system is disclosed in which intercom calls may be answered "hands-free" at the called station. Intercom calls are originated in the standard manner, with the subscriber picking up the handset at the calling station and dialing the number of the called station. A voice communication path is established through the station selector to the telephone set represented by the dialed number. DC bias on this communication path through the station selector activates a loudspeakers and microphone arrangement in the called telephone set. The called party may thus converse "hands-free" with the calling party by utilizing the activated loudspeaker and microphone of the station set, and need not manipulate the station set for the duration of the conversation.</p> |
