Feature Description
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).
Table 13 on page 112
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.
