• 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
