Abstract
PURPOSE:To eliminate a need for a time switch to exchange transmission time slot and reception time slot by constituting a channel in such a way that the transmission time slot is designated steadily on one highway channel, and the reception time slot is variably designated. CONSTITUTION:A digital key telephone system is constituted of a main equipment 100 and plural telephone sets 2A-2N connectd to the main equipment 100. The main equipment comprises codec 13A-13N, for which TxTS asigners 141A-141N as well as RxTS asigners 142A-142N are provided correspondingly. The TxTS asigners 141A-141N generate time slot signals to steadily designated transmission time slots for PCM code data, while the RxTS asigners 142A-142N generate time slots capable of designating variably reception time slots of respective PCM data each time for the codec 13A-13N.
