Schaltungsanordnung für die Übertragung von digitalen Nachrichtensignalen über ein nach einem asynchronen Transfermodus arbeitendes Breitband-Kommunikationssystem

摘要

The wideband communications network allows digital signals to be transmitted as information packets, with a packeting/depacketing device (P/D) at each system interface. Each of these devices has a counter (LG) with a fixed count period, the obtained count value acting as a time marking for the information packets. A buffer memory (PS) associated with each packeting/depacketing device provides temporary storage of the information packets handled by the wideband communication network (UES), its capacity equal to the max. number of packets transmitted in an interval corresp. to the max. packet propagation time variation. A counter (ZA) is associated with each buffer memory (PS) providing a time marking for the mean packet propagation time and indexed together with the first counter (LG). ADVANTAGES - Ensures original time sequence of transmitted packets is maintained.
