Pin Description
Alarm Pins for Receive Macro 1:
The ALARM1(0:4) outputs are controlled real time by the same internal
control signals that also cause the corresponding microprocessor interrupt.
The alarm conditions that are output on these pins are as follows:
ALARM1(0) = Loss of Signal in Macro 1
ALARM1(1) = Loss of Frame in Macro 1
ALARM1(2) = Loss of Pointer in Macro 1
ALARM1(3) = Path AIS in Macro 1
ALARM1(4) = Line AIS in Macro 1
