ABSTRACT:
A circuit for synthesizing multiple pulse code modulation (PCM) data in a full electronic switching system includes an upper processor for generating commands to request the pulse code modulation channel allocation and transmission of the pulse code modulated data. A plurality of lower processors generate the pulse code modulated data through their respective channels allocated according to the command of the upper processor. A data combining circuit combines the pulse code modulated data of the lower processors into the pulse code modulation channel data corresponding to the respective channels. A connection circuit transmits the pulse code modulation channel data.
