Chip KR1582IP1

The microcircuit is a circuit (LSI LU) for processing control signals and interaction of automatic telephone exchanges (ATS) and is designed for logical and temporal processing of control and interaction signals transmitted between exchanges via trunk lines, packed with IKM-30 equipment. The LSI is universal for various types of matching devices (CV) included in the IKM-30 equipment: outgoing MI and incoming CB, as well as for various modes of connecting the CS to the connecting lines (local, long-distance, decade-step, coordinate). The choice of operating modes is carried out by applying the appropriate levels to the inputs for changing the mode "MO" and the inputs for selecting the SI /CB "CS" mode.

In addition to the logical processing of SIV and the formation of output control signals CO, TF, EBL, LSI performs the function of holding the conversational path in case of failures and accidents in the DSP equipment, and also implements the functions of time selection of signals and correction of the duration of dialing pulses. All types of temporal signal processing are carried out digitally, which significantly increases the stability of the parameters.
