13 LINE INTERFACE FUNCTIONS
The line interface function in the DS2151Q contains three sections: the receiver, which handles clock and
data recovery; the transmitter, which waveshapes and drives the T1 line; and the jitter attenuator. Each of
these three sections is controlled by the Line Interface Control Register (LICR), which is described
below.
