one of the two radios in a Base Station is not working properly.
You can also use directed RSSI to prevent hand-off while you
find a cell edge. To measure the RSSI of a specific radio, you
must be in range of two Base Stations—the one you want to
measure and another Base Station.
You cannot measure the directed RSSI of both radios in the
Base Station at the same time.
Before you begin to measure directed RSSI
Use the Companion Provisioning Record to find the
following:
• the five-digit ID of the Base Station radio you want to
measure, by mapping the Base Station location to the time
compression multiplex (TCM) port. The first four digits
indicate the TCM port to which the Base Station is
connected. The last digit indicates the number of the radio
on the Base Station. For example, the number 03142 on
the Base Station is connected to TCM port 0314, and 2 is
the radio number. The five-digit number may be printed on
a label affixed to the lower right corner of the Base Station
mounting bracket.
• the radio IDs of all other Base Stations in the same
location.
To measure directed RSSI using your portable
1. Repeat steps 1 to 3 of “To measure undirected RSSI’’ on
page 77.
2. When the portable displays the Base Station ID you want
to measure, move out of the cell boundary range so that
hand-off occurs, and press or .
