Abstract

PURPOSE:To enable normal communication among synchronous terminals, by transmitting the synchronizing signal to the reception terminal when there is an interruption to the reception packet on the way of transfer, through the discrimination whether one packet is on the way of message transfer or not. CONSTITUTION:The transmission side exchange node is provided with the message half way display unit S3 which informs the packet is a part of a series of messages a7, a8, a9, and the reception side node is provided with the synchronizing signal transmitter S9 which transmits the synchronizing signal to the reception side subscriber terminal TR being the synchronous terminal. Further, the transmission side exchange node transmits the massage from the transmission side subscriber terminal Ts time it is the specified packet length, and the reception side exchange node transfers message to the terminal Tg every packet reception and transmits the synchronizing code to the terminal Tg if the reception packet is in shortage on the way of processing for a series of messages. Thus, normal communication can be made among the synchronizing terminals or from the terminal other than the synchronous terminal to be synchronous terminal.
