• If No LCR is selected, then the system allots a free trunk from the Trunk Access Group (TAG)
depending upon the rotation flag.
• If Time zone based LCR is selected, then the system finds the cheapest trunk from the group
depending upon the time on which call is made.
• If the cheapest trunk is free, it is allotted to the station so that the station user can dial out the
external number. If it is busy, the system searches for the next available cheaper trunk, if present in
the TAG and allots it to the station. The system checks in this manner until any free trunk can be
allotted to the station or otherwise plays the Busy Tone.
• If Number based LCR is selected, then the system allots a free trunk from the TAG as per the number
logic and the rotation logic and waits for the entire number string to be dialed out. It then finds out the
cheapest trunk from the group.
• If the cheapest trunk is free, the number is dialed out. If it is busy, the system searches for the next
available cheaper trunk, if present and allots it to the station. The system checks in this manner until
any free trunk can be allotted to the station or otherwise plays the Busy Tone.
• If Mixed LCR is selected, then the system finds the cheapest trunk from the TAG depending upon the
time, number logic and rotation logic.
• If the cheapest trunk with respect to the LCR logic is free, the system waits for the entire number
string to be dialed out. If dialed number string is allowed from this trunk, call is placed. If the trunk is
busy, the system searches for the next available cheaper trunk, if present and allots it to the station.
The system checks in this manner until any free trunk can be allotted to the station or otherwise
plays the Busy Tone.
