Avaya M3900 Installation Guide
M3900 Series Display-Based Accessory Module Installation Guide
This document describes how to install the Display-Based Accessory Module (DBA) (NTMN67xx) for the M3900
Series Digital Telephones. The DBA expands the number of lines and features available to the M3904 and M3905
telephones using soft-labeled keys.
Note: Only Phase III M3905 telephones support the DBA.
The DBA provides three layers of eight programmable line/feature keys, for a total of 24 keys. Use the Page key to
move among the three layers. Use the Edit command (under the Options menu) and the dialpad keys to change the
default 10-character programmable key labels.
Note: The DBA and Key-Based Accessory Module (KBA) are mutually exclusive. A telephone with one or two KBAs
configured or installed cannot have a DBA.
