Abstract
DE 2951721 A UPAB: 19930915 The circuit is used to assist in maintaining time frame synchronisation in various network branches. At each interconnecting point with the main transmission channel and spur, a time frame is generated which is matched to the characteristics of the spur, in particular, the signal transmission time for both the receive and send channels of the spur. The receive channel (EL) of a spur is interrupted with a synchronising pulse generated at the connecting point (NK). The pulse, undetected by coupled receivers, is retransmitted by the spur end station (ZE) on the send channel (SL). Connected subscriber equipment recognises this time interval as indicating time being available for transmission of data into the network (SL2). The necessary synchronising pulse control is carried out at the interconnector (NK).
