NRZ
NRZ Format Selection
. Only used in the digital framer only mode (LIU is disabled). A one
sets the MT9076 to accept a unipolar NRZ format input stream on RxA as the line input,
and to transmit a unipolar NRZ format stream on TxB. A zero causes the MT9076 to accept
a complementary pair of dual rail inputs on RxA/RxB and to transmit a complementary pair
of dual rail outputs on TxA/TxB.

Reserved
. Set this low for normal operation.
5
Res
Resistor
. Set this bit high to connect a 104 ohm internal resistor between RTIP and
RRING. This is activated where an external 20.8 ohm terminating resistor is in use on a T1
line.
4 - 3
RxA1-0
Automatic Receive Equalizer Control
. If both bits are set high, the receive equalizer is
turned on and will compensate for loop length automatically. The control bits RxEQ2-0 will
be ignored. If both are set low (00) then equalization will be actived using the control bits
RxEQ2-0.
2 - 0
RxEQ2-0
Receive Equalization Select
. Setting these pins forces a level of equalization of the
incoming line data.

These settings have no effect if either of RxA1 and RxA0 are set to one.
