HDLC0I
HDLC0 Interrupt.
Whenever an
unmasked HDLC0 interrupt occurs
(from the 4 kHz data link) this bit
goes high. Reading this register
clears this bit.

HDLC1I
HDLC1 Interrupt.
Whenever an
unmasked HDLC1 interrupt occurs
(from
the
DS1
signalling channel) this bit goes
high. Reading this register clears
this bit.

LCDI
Loop Code Detected Interrupt
.
When unmasked this interrupt bit
goes high whenever either the
loop up (00001) or loop down
(001) code has been detected on
the line for a period of 48
milliseconds. Reading this register
clears this bit.

1SECI
One Second Status Interrupt.
When unmasked this interrupt bit
goes high whenever the 1SEC
status bit (page 3 address 12H bit
7) goes from low to high. Reading
this register clears this bit.

5SECI
Five Second Status Interrupt
.
When unmasked this interrupt bit
goes high whenever the 5 SEC
status bit goes from low to high.
Reading this register clears this
bit.

Signalling
unmasked this interrupt bit goes
