Cisco 8831 Administration Guide

LED state definitions
LEDs on the Sound Base and DCU provide information about the state of the conference phone.
For example, green flashing lights on the Sound Base and on the DCU Call button indicate that there is an
incoming call. If the conference phone is on mute, then an incoming call will still flash green on the Call
button, but the LED for the DCU mute button is solid red, the sound base LEDs are solid red, and the mute
button on the Sound Base is also solid red.
The following table is a guide to the behaviour of the LEDs on the sound base and the DCU.
