Appendix 4: LED indication
On the front of the Codec, there are 18 LEDs to give the user precise information on the status of the Codec and the network
activity. The LED display is specially designed to provide the user with quick and accurate indications whenever there is a
change of status. G, Y, and R mean green, yellow, and red, respectively. (For convenience the LEDs in the example below
are diveded into 2 boxes refered to as Left and Right, although there is not such a division on the physical display)
