Description: The Oc3 Test Status LED is a read-only attribute which describes the condition of the Oc3 Test Status light emitting diode located on the Oc3 board. A value of on(1) indicates that a service effecting test is in progress and that the LED is illuminated. Will be off if no card present.

What is hcxOc3TestStatusLed?

This read-only on/off value mirrors the physical OC-3 Test Status LED on the card, lighting on(1) when a service-affecting test is in progress, and reporting off if no card is present. It lets an administrator remotely confirm a diagnostic test is actually running on the OC-3 card without a site visit. For example, a NOC operator monitoring a remote technician's diagnostic run on the optical card could watch this attribute change to on when the test begins.
