CO Line Calling & I-Use Indication
CO Line calling is the placement of a telephone call on the Public Switched Telephone Network. CO Line calling
includes: dialing local telephone numbers, dialing national long distance telephone numbers and dialing international
long distance telephone numbers.
Placing a CO Line call can be done in several ways:
•
CO Line Button
•
CO Line Group Access Code
•
CO Line Group Button
•
Speed Dial
When you are using an intercom or CO line the associated lamp will light green and flash at a double wink rate at
your telephone. This lamping condition is referred to as I-Use Indication (the indication that you are using this CO
Line.) Lamps for the same CO Line that you are using will light steady red at all other DX-80 digital telephones.
Calls placed on CO Lines are checked against the extension COS (Class Of Service). The conditions that can be
applied to the associated COS govern the call connection. If the dialed number is denied in the COS check, the call is
disconnected. If the Call passes the COS check, the call connection is allowed.
