3.5 Communications

The ONS 15216 EDFA2 can communicate in the following ways:

•Alarm Out relay contacts (RJ-45)

•Alarm LEDs

•Serial interface (EIA/TIA-232)

•Serial interface connected to a modem

•LAN interface (RJ-45)

3.5.1Alarm Out Relay Interface (RJ-45)

The ONS 15216 EDFA2 Alarm Out (RJ-45) port reports alarm status for the following:

•Loss or degradation of electrical power

•Laser pump overheating or excessive pump current, output power, gain, and case temperature

•Loss or degradation of optical network

These alarms can be connected to a network operations center (NOC) network management system (NMS) using the following methods:

•Cisco ONS 15454 miscellaneous discrete input

•Central Office alarm panel/system

Table 3-2provides the ONS 15216 EDFA2 RJ-45 alarm out pinout and alarm definitions.

Table 3-2 Alarm Pinout and Definitions (RJ-45)

Relay	Pinout		Description
0	1	(0+)	Loss of electrical power
	2	(0–)
1	3	(1+)	Laser pump temperature or bias is out of range; input power is out of
			tolerance for gain settings (Major)
	4	(1–)
2	5	(2+)	Loss of optical input signal or input signal is below threshold (Minor)
	6	(2–)
3	7	(3+)	Loss of electrical power or out of range for Bus A or Bus B while in duplex
			mode
	8	(3–)
