Optional devices are available to expand the capabilities of the 2420
telephone. They include:
•20A Stand—Every 2420 telephone comes equipped with a convertible
stand that allows you to install the 2420 telephone on your desktop or on a
wall. You must replace this convertible stand with the 20A stand if you are
using a 200A or 201A module.

standard tip/ring capabilities, allowing you to connect analog devices
(such as a fax machine) to the 2420 telephone.

telephone conversations. In addition, this module allows you to use two
additional headsets via the jacks on the 20A stand.
•EU24 Expansion Module—This module can display up to 24 additional
call appearance/feature buttons that have been programmed for your call
processing system. Buttons are displayed in two columns, with one
column displayed at a time on the EU24 screen.
