6.5.1.2 for configuration details.
In addition, a new parameter is introduced to limit the DECT base station transmit power to 100mW,
independent of the active regulatory domain. The active transmit power is sent to the DECT phone when
it registers its location with the OMM. The DECT phone adjusts its transmit power to the value received
from the OMM.
