NRZ
NRZ Format Selection
. Only used in the digital framer only mode (LIU is
disabled). A one sets the MT9074 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 MT9074 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.
6-4
TX2-0
Transmit pulse amplitude.
Select the TX2 –TX0 bits according to the line
type, value of termination resistors (RT), and transformer turns ratio used

REDBL
Receive Equalizer Disable
. If one the receive equalizer is turned off. If zero,
the receive equalizer is turned on and will compensate for loop length
automatically.
2-0
RES2-0
Receive Equalization Select
. Setting these pins forces a level of
equalization of the incoming line data.
