RRM Groups Configuration Settings
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.
22.4.2.4 Group Parameters
Combination
These textboxes allow the user to specify RRM subgroups called combinations. If the cover-
age 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. RRMs that are not assigned to combina-
tions poll individually, after the combinations poll.
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 combi-
nation. The numbers correspond to the numbers of the RRMs named in the RRM list on the
Remote Radio Modules menu (see page 241). For instance, "13" in the textbox for Combi-
nation 1 places RRMs 1 and 3 in that subgroup.
Note: When configuring RRM combinations, make sure the configured RRMs are sequen-
tial, 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.
