Intercom Calling
CPC-96, CPC-288, and CPC-576 All Versions
Description
The System provides two methods of intercom calling: 
•Voice Calling: Extension calls are connected immediately, without a ringing tone.
•Tone Calling: A ringing tone is sent to the called extension.
Extension Class of Service (COS) programming determines whether the default for the originating 
extension is voice or tone calling. Regardless of the default, you can toggle between voice or tone 
calling by entering the Tone-Voice Call feature code. For example, if the extension default is tone 
calling, you can make a voice call to another extension by entering the Tone-Voice Call feature access 
code.

Description
The System provides three types of line appearances
• Direct Station Select (DSS) / Busy Lamp Field (BLF) Appearances
• Direct Line (DL) Appearances

DSS/BLF Appearances
When a DSS/BLF key is programmed, it automatically provides one-touch dialing and DSS and BLF 
for the assigned extension numbers. If desired, the DSS/BLF key can also provide ring or delayed ring 
monitor. For example, you can set extension A as a DSS/BLF ringing key on extension B. When 
extension A rings, the LED of the DSS/BLF key on extension B flashes and the phone rings.
Ringing or delayed ringing can be set on extensions which have a BLF key. The LED of the DSS/BLF 
key flashes green
 during ringing and the display shows the BLF extension number.
When extension A is in use, the LED of the DSS/BLF key on extension B lights red. If one extension 
has the Call Forwarding or Do-Not-Disturb (DND) feature activated, the DSS/BLF key lights green.Action Result
