  22. Air Synchronization (Basic technology)

  23. “ Air Synchronization (Basic technology) - 1 Please understand the technology of DECT. Otherwise, we cannot understand the technology of Air Synchronization. The DECT signal consists of a transmitting frame (TX) and a receiving frame RX). And the composition of each frame (TX/RX) is as follows. Time Slot Frequency US-DECT is not supported Time decomposition “Time Division Multiplex” TX/RX Sequence Frequency Euro: f0-f9 US: f0-f4 TX TX RX RX

  24. “ Air Synchronization (Basic technology) - 2 One CS is connecting 1 x DECT-PS The one communication DECT signal consists of two control channels (D) and one voice channel (V). Sample (Control channel always uses even number frames. ) TS3 TS3 TX TX TS0 (D) , TS2 (D), TS3 (V)

  25. “ Air Synchronization (Basic technology) - 3 One CS is connecting 2 x DECT-PS If a CS is connecting 2 x DECT-PS, data channels and voice channel consist as follows, Sample The data channels (D) is the common data for both DECT-PS. The voice data is separated by the time slots. E.g. TS-3 and TS-4 TS3 TS3 TX TX No collision TS4 TS4

  26. “ Air Synchronization (Basic technology) - 4 One CS is connecting 8 x DECT-PS If a CS is connecting 8 x DECT-PS, data channels and voice channel consist as follows, Sample

  27. “ Air Synchronization (Basic technology) - 5 Super frame synchronization (Wired Connection) Internal Clock PRI/BRI The same DECT Sync-Clock on the cable-1 and the cable-2. System Clock Sync-Clock Sync-Clock DECT Sync-Clock Cable-1 Cable-2 CS-1 signal CS-2 signal are synchronized. PLL PLL Super frame synchronization CS-1 CS-2 Seamless handover is possible.

  28. “ Air Synchronization (Basic technology) - 6 Super frame synchronization (Wired Connection) When two or more CS are installed closely together, all the CS use different control channels. Sample D-1 D-2 CS-1 CS-2 DECT-PS can find CS by receiving D-Channel. Unless both CS-1 and CS-2 have synchronization, the DECT-PS cannot find any CS other than the CS it is already connected to.

  29. “ Air Synchronization (Basic technology) - 7 Super frame synchronization (Wired Connection) When two or more sets of CS are installed in closely, all the CS uses different control channels. Sample D-1, V-1 D-2, V-2 CS-1 CS-2 During handover (CS-1 to CS-2) the DECT-PS is communicating to two CSs.

  34. “ Air Synchronization (IP-CS) - 4 Legacy CS (KX-TDA0141/TDA042/TDA0158) A Legacy CS will receive its timing and synchronisation from the PBX, therefore TDA0141/TDA0142 and TDA0158 must be CS-Master. IP-CS (Mater) An IP-CS configured as CS-Master will create and send out its own timing and synchronisation. IP-CS (Slave) An IP-CS configured as CS-Slave will receive timing and synchronisation from either a legacy CS or IP-CS set to CS-Master
