Multiframe Synchronization Inter-
rupt. When unmasked an interrupt is
initiated when multiframe synchroni-
zation is lost. 1 - unmasked, 0 -
masked.
Interrupt

CRC-4 Multiframe Alignment. When
unmasked an interrupt is initiated
when CRC-4 multiframe synchroni-
zation is lost. 1 - unmasked, 0 -
masked.
Interrupt
10000000.
Remote Failure Interrupt. When
unmasked an interrupt is initiated
when the near end detects a failure
of the remote end CRC-4 process
based on the receive E-bit error
count. See the RFAIL status bit
description of page 3, address 19H. 1
- unmasked, 0 - masked. Interrupt

Remote Multiframe Loss Interrupt.
When unmasked an interrupt is initi-
ated when a remote multiframe alarm
signal is received. 1 - unmasked, 0 -
masked.
Interrupt

Second
unmasked an interrupt is initiated
when the 1SEC status bit changes
state. 1 - unmasked, 0 - masked.
Interrupt vector = 00001000.
Stop Interrupt. When unmasked an
interrupt is initiated when either
STOP0, STOP1, STOP0 or STOP1 is
high and a match or a mismatch
between the received data, and the
data in the code detect word (CDW)
and detect word mask (DWM). 1 -
unmasked, 0 - masked. Interrupt vec-
tor = 00000010.
Start Interrupt. When unmasked an
interrupt is initiated when either
START0,
START1,
START1 is high and a match or a
mismatch is made between the
received data, and the data in the
code detect word (CDW) and detect
word mask (DWM). 1 - unmasked, 0 -
masked.
Interrupt
00000010.
Data Interrupt. When unmasked an
interrupt is initiated when the data
received in selected time slots (per
time slot control words) matches the
data in the code detect word (CDW).

Bipolar Violation Error Insertion. A
zero-to-one transition of this inserts a
single bipolar violation error into the
transmit PCM 30 data. A one, zero or
one-to-zero transition has no function.
CRC-4 Error Insertion. A zero-to-one
transition of this bit inserts a single
CRC-4 error into the transmit PCM 30
data. A one, zero or one-to-zero transi-
tion has no function.
Frame Alignment Signal Error Insertion.
A zero-to-one transition of this bit inserts
a single error into the time slot zero
frame alignment signal of the transmit
PCM 30 data. A one, zero or
one-to-zero transition has no function.
Non-frame Alignment Signal Error Inser-
tion. A zero-to-one transition of this bit
inserts a single error into bit two of the
time slot zero non-frame alignment sig-
nal of the transmit PCM 30 data. A one,
zero or one-to-zero transition has no
function.
Loss of Signal Error Insertion. If one, the
MT9079 transmits an all zeros signal
(no pulses) in every PCM 30 time slot.
When
HDB3
encoding is activated no
violations are transmitted. If zero, data is
transmitted normally.
Unused.
Receive G.704 Framing Enable. If
high, the receive G.704 framing
functions are disabled. The device will
pass unframed G.703 data received on
RxA and RxB through the device
unaltered to DSTo. Once unframed
data
has
been
synchronization status bits will indicate
an out-of-synchronization state. When
low, this bit enables the receive G.704
framing functions of the device and the
synchronization status bits will function
normally.
Debounce Select. This bit selects the
debounce period (1 for 14 msec.; 0 for
no debounce). Note: there may be as
much as 2 msec. added to this duration
because the state change of the signal-
ling equipment is not synchronous with
the PCM 30 signalling multiframe.
