Trunk Access, Idle
Description
Allows the extension user to get an idle CO line for making an outside call by dialling the
feature number for "Local access / ARS" (9: [SP], 0: [NL], [JT] = default). An idle CO line is
automatically selected from the Trunk Groups assigned for the extension. The PT user can use
the Loop–CO button instead of dialling the feature number.
Conditions
• This feature functions when Automatic Route Selection (ARS) is not activated.
• Class of Service programming
COS (Class of Service) programming determines the trunk groups available for each
extension user.
• Hunting Order
An idle CO line is selected from the Trunk Groups assigned to the extension. If multiple
Trunk Groups are available, the Trunk Group hunting sequence is determined by System
Programming.
• Idle Line Preference — Outgoing
If Idle Line Preference — Outgoing is set by System Programming, the extension user can
access an idle CO line simply by going off-hook.
• <ICM type PT>
This feature requires a CO button (G-CO, L-CO or S-CO) assignment on a PT. Dialling the
line access code selects a CO button on a PT according to the priority as follows:
S-CO > G-CO > L-CO on a hunted Trunk Group
