Registering individual portables / 91

Before you begin measuring directed RSSI

Use the Companion Provisioning Record to find and note the following:

•the five-digit radio ID of the base station you want to measure, 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 03122 identifies radio 2 on the base station connected to TCM port 0312.

•the radio IDs of all other base stations in the same location.

Measuring directed RSSI using your portable

1.Perform an undirected Receive Signal Strength Indicator by following steps 1 to 3 in To measure undirected RSSI on page 84. To direct the Receive Signal Strength Indicator to the other radio of the base station, move out of range until hand-off occurs before moving on to step 2.

2.Press L. Wait for dial tone.

3.Press *899.

4.Enter the five-digit ID code for the base station radio you want to measure. The display shows this ID followed by the signal strength, for example 03121 - 67. If you have not established a connection with the desired base station radio, you hear a tone when you hold the portable to your ear.

5.Read your measurement. The system drops the link when you move out of range of your base station (no hand-off).
