adapter. Both type of USB headsets are stimulus devices, as the 
IP Deskphone can have complete control of the LEDs. 

 lists the features of the Avaya USB headset Adapter.

Key Event

Key press on the adapter generates events 
only with a state maintained and actions 
taken by the IP Deskphone. There is a one-
to-one mapping on most of the keys on the 
adapter to the keys on the IP Deskphone 
(the Avaya Enhanced Adapter has a Avaya 
logo key which does not exist on the 
IP Deskphone). 

illustrates the mappings:

Key press events on the adapter are sent to 
the IP Deskphone through the USB. When 
the IP Deskphone receives these events, it 
maps them to the corresponding key events 
as if the keys on the IP Deskphone are 
pressed.

LED

There are two LEDs on the adapters, one for 
the mute status and the other for message 
waiting. These two LEDs are also mapped 
to the corresponding LEDs on the 
IP Deskphone. The IP Deskphone 
synchronizes the LEDs status with that of 
the IP Deskphone: the Mute LED for mute 
indication and the Message Waiting LED for 
message waiting and incoming call (flash) 
indications. The Avaya USB Enhanced 
Adapter has an extra port to connect an 
external alerter. If there is an external alerter 
attached, the external alerter is kept 
synchronized with the Message Waiting 
LED.
