Functional Description:
The Signal Element Timing (clock) (S) is provided by the DCE. This means that the NTU will
output the correct clocking and that X.21 is a synchronous interface. Hardware handshaking
is done by the Control (C) and Indication ( I ) lines. The Control is used by the DTE and the
Indication is used by DCE.
