Abstract

PURPOSE:To eliminate the need for a message key box and to reduce an area required for installation, by transmitting a key for message waiting signal transmission without corresponding to extensions to the interval of a callout signal. CONSTITUTION:When message waiting display request information is discriminated according to the program operation of an exchanger controller, a relay MW of a message waiting signal transmission control circuit MWC provided between a callout signal transmission circuit RNG and an extension circuit LC is interrupted at a period when the transmission of callout signal is to be interrupted, allowing to transmit the message waiting signal to a message waiting display MWL (consisting of a neon lamp ML) corresponding to the extension TEL. The said operation can be performed with an easy operation by the operator of a switchbox through the dialing of an extension number and the operation of a common message waiting display key.
