Hi,
On the downlink SACCH, the BTS sends the MS a power order, which informs the MS as to which power to transmit on. When MS power control is activated in the cell, the power order can ‘instruct’ the MS to transmit on a lower or higher power.
In TEMs, you can’t see the SACCH message, but you can see the current ‘MS Power Control Level’ the GSM Radio Parameters window. The values given there are in multiples of 2, so eg, if the power control level is 3, the MS should transmit 6dB below the maximum power.
