RRM Groups
Remote Txon
This textbox allows the user to specify the number of fill characters sent by the ter-
minal radios before the terminals send message data. The allowable values range
from 3 to 32. The default value is 13.
Active Channel
This textbox allows the user to specify the radio channel to be used by all the RRMs
in the RRM group. The allowable values range from 1 to 20. The default value is 1.
GROUP PARAMETERS
Combination
These textboxes allow the user to specify RRM subgroups called combinations.
If the coverage areas of two or more of the RRMs in this RRM group do not overlap,
the non-overlapping RRMs may poll at the same time. This improves system
response time and reduces the amount of signalling on the network.
As an example, if the RRM group has 3 RRMs, and RRMs 1 and 3 don't overlap,
RRMs 1 and 3 may be placed in one subgroup (Combination 1). They will then poll
simultaneously. RRM 2 may be placed in another subgroup (Combination 2).
Polling alternates between the two subgroups.
To configure a combination, place the numbers of the RRMs in the textbox for that
combination. The numbers correspond to the numbers of the RRMs named in the
RRM list on the RRM Group Menu (see page 126). For instance, “13” in the textbox
for Combination 1 places RRMs 1 and 3 in that subgroup.
Note: When configuring RRM combinations, make sure the configured RRMs are
sequential, and are not missing numbers, which can happen when RRMs
are deleted and added. The combinations use the RRMs in the order that
they appear in the list, not how they are numbered in the list.
RRMs that are not assigned to combinations poll individually, after the combina-
tions poll.
