58.00 CO Access Instantly (CAI)
Description
When an extension user makes an outside call, the system seizes a CO line (if
available) and sends out dial signal after the toll restriction procedure in default
mode.
In some region, CO dial tone is returned to the system in a delayed timing.
If you want to send out dial signal after receiving the CO dial tone, program CO
Access Instantly feature.
When this feature is activated, a CO line is seized (if available) directly after
pressing a CO button or dialing a CO line access code.
Then the extension user can send dial signal to the central office after receiving
CO dial tone.
This feature is programmable on a trunk group basis.
In case of Local Trunk-Dial Access, system decides the mode by the top trunk
group of Local Trunk Hunt Sequence.
