Alarm function
Alarm signal processing
function
Receive an alarm signal reported by the equipment,
generate audio alarms for the signal, drive the cabinet
indicator, and output the alarm signal to the upper-
level equipment (such as the head of row cabinet).
Lightning protection
module alarm reporting
function
When the lightning protection module fails, output the
lightning protection module failure alarm to the
OTNM2000.

DC lightning protection
Differential mode
protection
An 8/20us 2kA test surge current is imposed in the
positive and negative directions between the external
power input terminals -48 V and 0 V. The PDP can
work normally after the surge current is imposed.
