The following RSSI display thresholds have been observed on a North American
C139 phone (sw ver 1.0.07) tested on our CMU200 in the PCS band; each number of
bars given below appears when the BCCH signal level on the CMU200 is set to
greater than or equal to the corresponding number:

5 bars threshold: -86 dBm
4 bars threshold: -94 dBm
3 bars threshold: -98 dBm
2 bars threshold: -102 dBm

1 bar appears until complete loss of service

No Pirelli-like 5 dB hysteresis is seen on this phone.
