Trunk Access

Description
The following methods can be used to access a trunk:
Method
Idle Line Access
(Local Access)
Trunk Group Access
S-CO Line Access
Conditions
• COS programming determines the trunk groups available for making calls (→ Trunk Group Number
[500]).
• Trunk numbers can be referred on a trunk port basis (→ LCOT/BRI Trunk Number Reference [409]).
• Button Assignment
A flexible button can be customised as a G-CO, L-CO, or S-CO button as follows:
Loop-CO (L-CO)
Group-CO (G-CO)
Single-CO (S-CO)
It is possible to assign trunks in the following ways:
– The same trunk to the S-CO button and to a G-CO button
– The same trunk group to more than one G-CO button
– More than one L-CO button
Dialling the Trunk Access number selects a CO button in the following order: S-CO → G-CO → L-CO
• Direct Trunk Access
Pressing an idle CO button automatically switches on the hands-free operation mode and allows a user
to use On-hook Dialling. The user need not press the SP-PHONE button, MONITOR button, or lift the
handset.
• Group Hunting Order for Idle Line Access
An idle trunk is selected from the trunk groups assigned for Idle Line Access. If multiple trunk groups
are available, the trunk group hunting sequence can be determined through system programming.
• Trunk Hunting Order for Idle Line Access and Trunk Group Access
The trunk hunting sequence in a trunk group (from lowest numbered trunk, from highest numbered
trunk or rotation) can be determined through system programming.
