The ALIS digital command/indication interface to the line and external equipment is
configured and evaluated by the Extended Operation (XOP) command. Other common
functions are also assigned by this command.

RW
LSEL
6.3.1
Any interrupt indications can be monitored in the interrupt register. Interrupts can be
signaled via a logic ’1’ on the INT line. After an indication has occurred, further loading
of the interrupt register is locked until its contents are read via the -controller interface.
Reading the interrupt register XR0 releases the lock and the INT line is set to low again.
See “Interrupt Controller” on page 60 for more details.
