ABSTRACT:
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.
