Hi, thanks for your answer.
The information that I have from the operator is that the unit has transmitted continuously on GSM channel 88 (907.6 MHz) and at a second location on GSM channel 99 (909.8 MHz). The operator says that by transmitting continuously on these frequencies other ME:s are disturbed and more calls then normal are disconnected.
I’m not that familiar with all part of the Base station but I have assumed that they mean the BCCH.
Our unit are not able to call when this happens and when the unit is restarted all is OK.
