LINE INTERFACE FUNCTIONS
The line interface function in the DS21354/DS21554 contains three sections: (1) the receiver, which
handles clock and data recovery; (2) the transmitter, which waveshapes and drives the E1 line; and (3) the
jitter attenuator. Each of these three sections is controlled by The Line Interface Control Register (LICR)
contrlls each of these three sections.
