Table 35 - Interrupt Mask Word Three (T1)
Unused.
Loop Code Detected Interrupt Mask. When unmasked an
interrupt is triggered when either the loop up (00001) or loop down
(001) code has been detected on the line for a period of 48
milliseconds. If 1 - unmasked, 0 - masked.
One Second Status Interrupt Mask. When unmasked an interrupt
is initiated when the 1SEC status bit (page 3 address 12H bit 7)
goes from low to high. If 1 - unmasked, 0 - masked.
Five Second Status Interrupt Mask. When unmasked an interrupt
is initiated when the 5 SEC status bit goes from low to high. If 1 -
unmasked, 0 - masked.
Bit Oriented Message Interrupt Mask. When unmasked an
interrupt is initiated when a pattern 111111110xxxxxx0 has been
received on the FDL that is different from the last message. The
new message must persist for 8 out the last 10 message positions
to be accepted as a valid new message. If 1- unmasked, 0 -
masked.
Signaling Interrupt Mask. When unmasked an interrupt will be
initiated when a change of state (optionally debounced - see DBEn
in the Data Link, Signaling Control Word page 1 address 12H) is
detected in the signaling bits (AB or ABCD) pattern. If 1 -
unmasked, 0 - masked.
