Functional Description:
The Signal Element Timing (clock)
(S)
is provided by the DCE. This means
that the NTU is 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 the DCE one.
