The Channel Usage parameter is used to set a channel usage scheme for Network Access Points (NAPs), also called trunk groups, in order to avoid call collision. Values for this parameter are selected from a drop-down list. The Channel Usage parameter can take on the following values:
ISDN, SS7 and CAS
- Round-Robin : Traverse, in order, all timeslots of the NAP from first timeslot of first trunk to last timeslot of last trunk
- Lowest Timeslot: Start from lowest timeslot of every trunk and will reuse them if they are idle
- Highest Timeslot: Start from highest timeslot of every trunk and will reuse them if they are idle
- Lowest Mapping ID: Start from lowest timeslot of first trunk, second lowest of first trunk, etc. Once the first trunk is full, will start using second trunk
- Highest Mapping ID: Start from highest timeslot of last trunk, second highest of last trunk, etc. Once the last trunk is full, will start using second-to-last trunk
SS7 only
- Lowest CIC : Start from lowest CIC value of the NAP and will reuse them if they are idle
- Highest CIC : Start from highest CIC value of the NAP and will reuse them if they are idle
- Odd Lowest CIC : Start from lowest CIC, odd value, and will reuse them if they are free. Will only use even CICs when all odd CICs are used.
- Odd Highest CIC: Start from highest CIC, odd value, and will reuse them if they are free. Will only use even CICs when all odd CICs are used.
- Even Lowest CIC : Start from lowest CIC, even value, and will reuse them if they are free. Will only use even CICs when all even CICs are used.
- Even Highest CIC : Start from highest CIC, even value, and will reuse them if they are free. Will only use even CICs when all odd CICs are used.
