3.8 Dynamic Channel Allocation (DCA) Display – Portable Telephone
The Portable Telephones can be switched to DCA mode. In this mode the Portable Telephone
displays information regarding the radio interface, like Base Station number, carrier, time slot
number, RSSI, RQI, etc., while calls can still be made and received normally. The call indicator
shows the user the hook status.
Note:
Activating the DCA mode reduces the normal functioning of the Portable Telephone. It is therefore
recommended only to use this facility in exceptional cases, e.g. when service requires such an
action.
