3.8Dynamic 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.
