Abstract
PURPOSE:To effectively use a transmitting path by selecting the transmitting path according to whether the signal from a subscriber terminal is the voice signal or data, simultaneously in the case of the voice signal, shortening the bit length by means of an ADPCM conversion and transmitting the signal. CONSTITUTION:For a channel control circuit SPC4, the signal from a called side subscriber terminal T1 is the data, the data from the T1 are transmitted through a subscriber circuit LC2, a time division switch TDSW3, a digital trunk interface DTI16, and a transmitting path 21. On the other hand, when the signal from the T1 is the voice signal, after the voice signal from the T1 is transmitted to the LC2, the TDSW3, and an ADPCM7, the ADPCM7 ADPCM-converts the voice signal and shortens the bit length. The shortened voice signal is concentrated along with the voice signal of an ADPCM8 by an MUW9, and sent to a transmitting path 2 by a DTI10.
