Intercom; Direct Station Select (Dss) Keys; Placing An Intercom Call - IBM 412 - 412 Corded Phone Installation And Operation Manual

The Intercom function allows extension-to-extension conversations (phones must be connected to [LINE 1]).
That means you can speak with another party without having to dial seven digits (using an outside line). As
you direct an intercom call to an extension that extension will ring and display a flashing ICM LED.

DIRECT STATION SELECT (DSS) KEYS

The phone system is preprogrammed so that with the touch of a button, you can dial any of the extensions
11–22. Although not labeled, the buttons correspond to extension numbers 11 through 22 in sequential or-
der.
