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. RRMs that are
not assigned to combinations 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
combination. The numbers correspond to the numbers of the RRMs named in the
RRM list on the Remote Radio Modules menu (see page 238). 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.
22.4.2.5 Remote Radio Modules
This menu displays the RRMs that comprise this RRM Group, including each
Description, IP address, and Port number as set in the Connectivity Options sub-
menu for the 9160 G2s set in RRM operating mode (see “Connectivity Options:
RRM Mode” on page 229). Each RRM may be enabled or disabled from this menu.
