Description
Use this program to set up LCR trunk groups. Set up LCR trunk groups
before setting up Time Priority Route Tables.
LCR uses 4 trunk groups, each consisting of 4 trunks. The trunks in each
group are prioritized according to their cost-effectiveness, so that LCR tries
the highest priority trunk in the group first, then the next highest, etc.
Different LCR trunk groups are used at different times of the day. The time
of day during which an LCR trunk group is used is determined by the Xme
Priority Route Tables (see program address FF8 5#).
LCR selects trunks from trunk groups in priority order; the most cost-
effective trunks receive the highest priority, so that LCR tries to use them
first. The priority of a trunk is determined by its position in the trunk group.
A trunk in position 1 has the highest priority in the group. A trunk in position
4 has the lowest priority in the group. LCR trunk selection is illustrated in the
following table.
