Line Access Keys
One of the following 3 types of line keys must be used to select an exchange line when
making a call.
• Trunk Group (G-CO) key
• Other Exchange Lines (O-CO) key
• Single Exchange Line (S-CO) key
• A flexible line key can be assigned as a Line Access Key (G-CO, O-CO or S-CO) in
Proprietary Telephone Settings. Once a flexible line key is assigned as a Line Access Key, it
provides the line status using lighting patterns and colour indication. Please refer to “2.2
LED Indication”.
• You can set the G-CO and S-CO keys on one telephone. Incoming and outgoing calls on the
line are shown on the key in the following priority. S-CO > G-CO
Single Exchange Line (S-CO) Key
A S-CO key is an exchange line access key. This allows you to access a specific line by
pressing a S-CO key. An incoming call can be directed to a S-CO key.
