Measuring directed RSSI

You may want to measure the RSSI between a portable and a specific base station radio. For example, you may suspect that 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.

Note: You cannot measure the directed RSSI of both radios in the base station at the same time.

Before you measure directed RSSI, use the Programming Record to find and note the following:

•the five-digit ID of the base station radio you want to measure. Do this by mapping the base station location to the 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 number might be printed on a label attached to the base station mounting bracket.
