Exchange of clock signals
The way clock signals are exchanged between DTE and DCE depends on the type of interface:
• V24, V35, V36, RS530, HSSI: these interfaces have separated clock signals to synchronize transmit
(TxClk or ExClk) and receive (RxClk) data:
• X21 interface uses only one clock signal (S or X) to synchronize both transmit and receive data:
• G703 interface uses codirectional timing, this means that clock information is encoded in the data signal:
