4-232
Bit
Name
Functional Description
7
TIU0
(0)
Transmit International Use Zero.
When CRC-4 operation is disabled,
this bit is transmitted 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, this
bit is ignored.
6
CRCM
(0)
CRC-4 Modification. If one, activates
the CRC-4 remainder modification
function when the device is in trans-
parent mode. The received CRC-4
remainder is modified to reflect only
the changes in the transmit DL. If
zero, time slot zero data from DSTi
will not be modified in transparent
mode.
5
RST
(0)*
Reset. When this bit is changed from
low to high the MT9079 will reset to
its default mode. See the Reset
Operation section.
4
ARAI
(0)
Automatic RAI Operation. If zero, the
Remote Alarm Indication bit will func-
tion automatically. That is, RAI = 0
when basic synchronization has been
acquired, and RAI = 1 when basic
synchronization
acquired. If one, the remote alarm
indication bit is controlled through the
TALM bit of the transmit non-frame
alignment control word.
has
not
been
3
AUTY
(0)
Automatic Y-Bit Operation. If zero,
the Y-bit of the transmit multiframe
alignment signal will report the multi-
frame alignment status to the far end
i.e., zero - multiframe alignment
acquired, one - lost. If one, the Y-bit is
under the manual control of the trans-
mit multiframe alignment control
word.
2
MODE
(0)
Transmit Mode. If one, the MT9079 is
in transparent mode. If zero, it is in
termination mode.
1
CSYN
(0)
CRC-4 Synchronization. If zero, basic
CRC-4 synchronization processing is
activated, and TIU0 bit and TIU1 bit
(frames 13 and 15) programming will
be overwritten. If one, CSYN is dis-
abled, the transmit CRC bits are pro-
grammed by TIU0 and the transmit E-
bits are programmed by either TxB0,
TxB1 or TIU1.
0
AUTC
(0)
Automatic CRC-interworking. If zero,
automatic CRC-interworking is acti-
vated. If one, it is deactivated. See
Framing Algorithm section.

TIU1
(1)
Transmit International Use One.
When CRC-4 synchronization is dis-
abled, and TxB0 and TxB1 are not
connected to channel zero, this bit is
transmitted on the PCM 30 2048
kbit/sec. link in bit position one of
time slot zero of non-frame alignment
frames (international use bit). If
CRC-4 synchronization is enabled or
TxB0 or TxB1 are connected to time
slot zero, this bit is ignored.

---
Unused.
5
TALM
(0)
Transmit Alarm. This bit is transmit-
ted on the PCM 30 2048 kbit/sec. link
in bit position three of time slot zero
of non-frame alignment frames. It is
used to signal an alarm to the remote
end of the PCM 30 link (one - alarm,
zero - normal). This control bit is
ignored when
ARAI
is zero (page 1,
address 11H).
4 - 0
TNU4-8
(11111)
Transmit National Use Four to Eight.
These bits are transmitted on the
PCM 30 2048 kbit/sec. link in bit posi-
tions four to eight of time slot zero of
non-frame alignment frame. See Sa4
- Sa8 control bits of the DL selection
word (page 1, address 10H).
Table 27 - TNFA Control Word
(Page 1, Address 12H)
* Not affected by the RST function - the state shown in ( ) can
be achieved by using the RESET function.
