摘要： An apparatus for receiving multi-channel caller identification data in a switching system with a path forming portion for forming a path to receive the caller identification data in response to an incoming ring signal from a plurality of central office lines; a multiplexer for selecting one of a plurality of channel signals containing the call identification data and received from the path forming portion; a decoder for sampling an analog signal of a corresponding channel selected by the multiplexer at a predetermined sampling frequency, to thereby convert the analog signal containing the call identification data into a PCM signal; a time switch for switching and outputting the converted PCM signal converted in the decoder and containing the call identification data to a corresponding channel; a demodulator for receiving the PCM signal output through the time switch to thereby demodulate the caller identification data; and a controller establishing a path for the caller identification data in response to the detection of the caller identification data, the controller controlling the display of the caller identification data by analyzing data demodulated in the demodulator.

摘要： A method for controlling and processing a call from one keyphone to a busy keyphone utilizing a keyphone main unit connected to an office line and a plurality of keyphones in a keyphone system, the busy keyphone being connected to a third keyphone, wherein the keyphone main unit receives an input sequence of dialed numbers from the one keyphone; determines when the input sequence is complete; transmits a first display signal to the busy keyphone to cause the busy keyphone to display a message indicating an incoming call from the one keyphone; determines whether the busy keyphone is in a forced off-hook ring mode; transmits a busy tone to the one keyphone when it is determined that the busy keyphone is not in the forced off-hook ring mode; checks for an input signal from an off-hook ring button on the one keyphone; transmits an off-hook ring signal to the busy keyphone when it is determined that the busy keyphone is in the forced off-hook ring mode or when it is determined that the off-hook ring button on the one keyphone was pushed, the off-hook ring signal causing the busy keyphone to perform an off-hook ring; transmitting a ring back tone and a camp-on-busy signal to the one keyphone; checks for an input signal indicative of an on/off activation of a switch hook or a CALL button on the busy keyphone; and stops the off-hook ring of the busy keyphone and connecting a speech path between the one keyphone and the busy keyphone when on/off activation of the switch hook or pushing of the CALL button on the busy keyphone is detected.
