Figure 8: Key-based expansion module accessory
To log Calling Party Name Display (CPND) the telephone set has to "know" the moment when
an incoming call either is answered or unanswered. For this purpose, the set tracks the states of
the icons. This is possible for the keys/icons located on the main set; however, the set is not
able to track states of the keys/icons located on the add-on modules (that is, the KBA and
DBA). As a result, although the set receives and displays the CPND for the call coming to the
attached DBA or KBA, it is unable to log the CPND.
Display-based Expansion Module (DBA)
The DBA is an optional add-on module for the Avaya 3904 and 3905 Digital Deskphones
exclusively. The module attaches to a set to increase the number of programmable feature
keys on the set by 24 for a total of 56 keys.
The DBA has keys 33-56 supporting up to three layers of eight programmable feature keys. It
has eight self-labeled keys with the feature labels next to the key. A Page fixed-key allows
switching between the three layers of self-programmable feature keys. The labels change
according to the features programmed for the next logical set of feature keys shifting through
the display. A visual indicator shows which page (or layer) of self-labeled programmable feature
keys is in use.
The first key of the DBA maps to Key 33. The user can change the feature key labels by
selecting "Change feature key label" from the Options list on the Avaya 3904 or 3905 Digital
Deskphone.
Use SERVORD commands to provision the DBA as a line option. Once a DBA has been added
to a set, you can assign feature/DNs to the extra keys. The Meridian SL-100 uses a key map to
download the DBA key assignments to the set. The DBA firmware handles the self-key labeling.
The self-key label can be up to 10 characters in length.
Only one DBA can be added onto a either an Avaya 3904 or Avaya 3905 set only. You cannot
combine a DBA with a KBA.
