Nortel Meridian M3904 Installation Manual

M3900 Series Key-Based Accessory Module Installation Guide
This document describes how to install the Key-Based Accessory Module (KBA) (NTMN37xx) for the M3900 Series
Digital Telephones. The KBA provides 22 additional line/feature keys for the M3904 and the M3905 telephones. You
can add a second KBA, for a total of 44 additional line/feature keys. In addition to the KBA, you will need to order
the Key-Based Accessory Module Kit 1 (NTMN38AA), which includes the Single KBA Footstand Assembly. If you are
adding a second KBA, you will also need to order the Key-Based Accessory Module Kit 2 (NTMN38BA), which
includes the Expansion KBA Footstand Assembly.
Note: The KBA and Display-Based Accessory (DBA) modules are mutually exclusive. A telephone with one or two
KBAs configured or installed cannot have a DBA.
