Measuring RSSI for a C3020 (Canada only)

The Receive Signal Strength Indicator (RSSI) is a measurement of the signal strength the Base Station receives from the portable. The Base Station controls the power transmitting mode of the portable. When the Base Station receives a weak signal, it instructs the portable to transmit in high-power. When the Base Station receives a strong signal, it instructs the portable to transmit in low-power. The strongest RSSI value the portable displays is -44 dBm. The weakest RSSI value the portable displays is approximately -85 to -95 dBm.

Receive Signal Strength Indicator overrides normal display.
