Optional 60-Key Expansion Console for use with the 48-Key Feature Phone
The 60-Key Expansion Console adds 60 additional programmable feature keys to a designated user's
extension. The console is connected to its host 48-Key Digital Feature Phone via a special cable (pro-
vided) and doesn't require a separate station port of its own.
You program the Expansion Console's keys just as you do the programmable feature keys on your ESI
Feature Phone, using either direct or traditional programming.
Note: Up to four Expansion Consoles can be installed in a fully configured system.
