Description
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). (The mappings are listed following this
table.)
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.
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.
When an Avaya USB Mobile or Enhanced Headset
is connected to the IP Deskphone, after
enumeration, the IP Deskphone flashes the LEDs on
the headset for a short duration to indicate the
headset is ready to use.
Both adapters have a back light to allow easy
identification of the adapters. If the back light is
enabled in the Headset screen, the back light of the
adapter turns on after enumeration.
If there is a voice message waiting on the IP
Deskphone, the IP Deskphone turns on the red
Message Waiting LED on the IP Deskphone and on
the adapter. The IP Deskphone turns off the red
Message Waiting LED if there is no voice message
waiting.
The Avaya USB Enhanced Adapter has a port to
allow an External Alerter (large LED indicator) to
attach to the adapter. The IP Deskphone uses HID
commands to keep the External Alerter
