dB values are never linear, they're logarithmic.  dBm is vs. Power.

The value is the absolute tranmission power of the MS (uplink) in dBm.
It has nothing to do with max_power_red, whcih is about the relative
reduction of downlink transmit power respective to the nominal transmit
power of the BTS in downlink.

The values are all specified in the relevant GSM specs.
