Preliminary Information

Bit

Reserved.
Must be kept at 0 for normal operation.
6
TE
Transmit E bits.
When zero and CRC-4 synchronization is achieved, the E-bits transmit the
received CRC-4 comparison results to the distant end of the link, as per G.703. That is,
when zero and CRC-4 synchronization is lost, the transmit E-bits will be zero. If one, and
CRC-4 synchronization is lost the transmit E-bits will be one.
5
TAIS16
Transmit AIS Time Slot 16
. If one, an all ones signal is transmitted in time slot 16. If zero,
time slot functions normally.
4
TxAO
Transmit All Ones.
When low, this control bit forces a framed or unframed (depending on
the state of Transmit Alarm Control bit 0) all ones to be transmit at TTIP and TRING.
3
Einv
Ebit Error Inversion
. When zero, received Ebits set to zero are counted in the Ebit error
counter and interrupt generator. When one, Ebits set to one are counted in the Ebit error
counter and interrupt generator.

EXZ
Excess Zeros.
Setting this bit causes each occurance of received excess zeros to
increment the Line Code Violation Counter. Excess zeros are defined as 4 or more
successive zeros for HDB3 encoded data, or 16 or more successive zeros for non-HDB3
encoded data.
4
SaBorNi
Sa Bit or Nibble
. Set this bit to determine the criteria for interrupts due to transitions of Sa
bits. If set to one, a change of state of any Sa bit is the criteria. If set to zero, a change of
state of an Sa nibble is the criteria. Note that the selected event can only trigger an interrupt
if the interrupt mask bit SaIM is set high in the Interrupt Mask Word Two - page 1 address
1DH bit 0.
3
RxTRSP
Receive Transparent Mode
. When this bit is set to one, the framing function is disabled on
the receive side. Data coming from the receive line passes through the slip buffer and drives
DSTo with an arbitrary alignment. When zero, the receive framing function operates
normally.
2
TxTRSP
Transmit Transparent Mode
. If one, the MT9076 is in transmit transparent mode. No
framing or signaling is imposed on the data transmit from DSTi onto the line. If zero, it is in
termination mode.
1
TIU1
Transmit International Use One
. When CRC-4 operation is disabled (CSYN=1), this bit is
transmit on the PCM 30 2048 kbit/sec. link in bit position one of time-slot zero of non-frame-
alignment frames. It is reserved for international use and should normally be kept at one. If
CRC processing is used, i.e., CSYN =0, this bit is ignored.
0
TIU0
Transmit International Use Zero
. When CRC-4 operation is disabled (CSYN=1), this bit is
transmit on the PCM 30 2048 kbit/sec. link in bit position one of time-slot zero of frame-
alignment frames. It is reserved for international use and should normally be kept at one. If
CRC processing is used, i.e., CSYN =0, this bit is ignored.
