Extension to Network Extension Calling
(CPC-EX)
Descriptions
An extension user on one Networked DBS may call an extension on another
Network DBS by simply dialing the four digit extension number.
The actual mechanism used to connect to the other network DBS is through
T-1 trunks. Calling between network nodes therefore resembles trunk calling
as follows:
• The display operates similar to CO trunk calling; no called party absence
messages are displayed.
• The DBS provides one method of network extension calling: tone calling.
With tone calls, a ringing tone is sent to the called extension.
• No features such as call waiting, camp-on, message waiting, offhook voice
announce, barge-in, etc. are available for network calls between nodes.
Note:
Any calls to extensions on the same node retain the full compliment
of extension calling features.
Operation
To make a Call to an Extension on another Networked DBS:
1. Pick up the handset.
The phone issues intercom dial tone.
Note:
If you are calling from an extension programmed for prime line
preference, press the FF key programmed for intercom operation.
2. Dial the four digit extension number.
• The number dialed appears on your display.
• “NET TALK GN” (where “N” is the network trunk group number)
appears on the
called
phone display.
• An FF key LED lights if assigned to the network trunk or the
EXT
LED lights.
• If the called extension is busy, busy tone is returned.
