ZT5550 Configuration
The ZT5550 is used in release 1.2 equipment for the utility bus controllers and
radio sector controllers. It may be necessary to modify the configuration switches
on the ZT5550, as the basestation uses a configuration of these cards that differs
from the manufacturer’s original settings.
NOTE: If the controller cards are pre-installed in the shelves,
then they have already been configured and this procedure is not
required.
Table C.1 shows the correct settings of the configuration switches.
