HDLC0
HDLC0 Select
. If one, then
HDLC0 is connected to the data
link on selected Sa bits at a rate of
4, 8, 12, 16 or 20 kbits/sec. If zero,
HDLC0 is deselected and all
HDLC0 interrupts are masked.

HDLC1
HDLC1 Select
. If one, then
HDLC1 is connected to time slot
16 in CCS mode. If zero, HDLC1 is
deselected
and
interrupts are masked.

RxTRSP
Receive
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
operates normally.

TxTRSP
Transmit Transparent Mode
. If
one, the MT9074 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.

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.

TMA1-4
Transmit Multiframe Alignment
Bits One to Four
. These bits are
transmitted on the PCM 30 2048
kbit/sec. link in bit positions one to
four of time slot 16 of frame zero
of every signalling multiframe.
These bits are used by the far end
to identify specific frames of a
signalling multiframe. TMA1-4 =
0000 for normal operation.

X1
This bit is transmitted on the PCM
30 2048 kbit/sec. link in bit
position five of time slot 16 of
frame zero of every multiframe.
X1 is normally set to one.
2
Y
This bit is transmitted on the PCM
30 2048 kbit/sec. link in bit
position six of time slot 16 of
frame zero of every multiframe. It
is used to indicate the loss of
multiframe
alignment
remote end of the link. If one -
loss of multiframe alignment; if
zero
-
multiframe
acquired. This bit is ignored when
AUTY is zero (page 01H, address
