through bit 6 of the per time slot control words (pages
7 and 8).
c) DWM7-0 - Detect Word Mask 7 to 0 (page 1,
address 19H) is an eight bit code, which determines
the bits that will be considered in the comparison
between the receive data and the Code Detect Word
(CDW7-0). If one, the bit position will be included - if
zero, the bit position will be excluded.
The DATA interrupt vector value is 02H located on
page 4 address 12H.
Alarms
The MT9079 will detect and transmit the following
alarms:
a) Remote Alarm Indication - bit 3 (ALM) of the receive
NFAS;
b) Alarm Indication Signal - unframed all ones signal
for at least a double frame (512 bits) or two double
frames (1024 bits);
c) Channel 16 AIS - all ones signal in channel 16;
d) Auxiliary pattern - 101010... pattern for at least 512
bits;
e) Loss of Signal - a valid loss of signal condition
occurs when there is an absence of receive PCM 30
signal for 255 contiguous pulse (bit) positions from the
last received pulse. A loss of signal condition will
terminate when an average ones density of at least
12.5% has been received over a period of 255
contiguous pulse positions starting with a pulse; and
f) Remote Signalling Multiframe Alarm - bit 6 (Y-bit) of
the multiframe alignment signal.
Automatic Alarms
The transmission of RAI and signalling multiframe
alarms can be made to function automatically from
control bits ARAI and AUTY (page 1, address 11H).
When ARAI = 0 and basic frame synchronization is
lost (SYNC = 1), the MT9079 will automatically
transmit the RAI alarm signal to the far end of the link.
The transmission of this alarm signal will cease when
basic frame alignment is acquired.
When AUTY = 0 and signalling multiframe alignment is
not acquired (MFSYNC = 1), the MT9079 will
automatically transmit the multiframe alarm (Y-bit)
signal to the far end of the link. This transmission will
cease when signalling multiframe alignment is
acquired.
Interrupts
The MT9079 has an extensive suite of maskable
interrupts, which are divided into eight categories
based on the type of event that caused the interrupt.
Each interrupt category has an associated interrupt
vector described in Table 7. Therefore, when
unmasked interrupts occur, IRQ will go low and one or
more bits of the interrupt vector (page 4, address 12H)
will go high. In processor and controller modes after
