Abstract

PURPOSE:To communicate with an MODEM in a remote station, by assembling a digitized in-station MODEM in a transmission controller and directly coupling it to a digital channel. CONSTITUTION:A digital voice frequency signal transmission circuit SIG CS is controlled with an instruction from a central processing unit CP, and the output F2 is connected to a multiplex circuit MUX directly. This signal is in D/A conversion at a codec CODEC via a digital switch TDSW and multiplex separation circuit DMUX and transmitted from a trunk circuit TRK to a remote station. On the other hand, the signal F1 from the remote station is transmitted to a central processing unti CP via the trunk circuit TRK, CODEC, MUX, TDSW, DMUX, and a digital voice frequency signal reception circuit SIG REC.
