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, before starting to use first timeslot of first trunk again.
- 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. Will reuse the channels if they are idle.
- 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 trun. Will reuse the channels if they are idle.
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 idle. 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 idle. 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 idle. 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 idle. Will only use even CICs when all odd CICs are used.
