Description
A Single-CO (S-CO) button is a CO line access button. This allows
the digital proprietary telephone user to access a specific line by
pressing an S-CO button. An incoming call can be directed to an S-
CO button.
Conditions
• The default setting for CO buttons is changeable. (Flexible CO Button)
• An S-CO button provides CO line status.
• It is possible to assign one CO line to both an S-CO and a G-CO button.
• If Automatic Route Selection (ARS) is set, it is overridden by an
outgoing call made by pressing the S-CO button.
• Incoming calls appear on the digital proprietary telephone, when an
extension is assigned as the incoming call destination and an S-CO, G-
CO and/or L-CO button is assigned.
• Immediate, delayed, no ringing or no incoming call (disable) can be
selected on an extension–CO line group basis.
• The DPT user can choose a desired ringing tone type for the S-CO
button by system or station programming.
