• Dry contact alarms are available through a 9-pin D-type connector that provides dry contact for internal MAJOR, MINOR and external alarms.
  MAJOR alarms occur when power supply fails, supply voltage is below a threshold, code download fails, LOS, PLL unlock is received, LOF or the ambient temperature inside the box exceeds +65øC.
  Minor alarms occur when a string of all "1", LAIS or LRDI are received on the links.

• A voltage (12-48V) between pins 1 and 2 (See Table 1 for the connector pin assignments) invokes external alarm input.

Table 1. Connector Pin Assignment Table

Type	Contact	Pins
External Alarm	Normally open	1 and 2
MINOR Alarm	Normally closed Normally open	9 and 4 9 and 5
MAJOR Alarm	Normally closed Normally open	3 and 8 3 and 7
