Ericsson LBI-39224 State Table, Current State, Next State, DC Controlled Station State Mapping

LBI-39224

State Table

The State Table list box contains all of the possible programmable commands for a base station. Select the required commands to program from this list box, the selected command will be displayed in the Selected Command text box.

Current State

The Current State field displays the control current levels used to control the DC control base station.

Next State

The Next State field has seven text boxes which can be edited with the required DC levels for the command displayed in the Selected Command text box. The DC levels entered for the selected command must match the base station levels for proper remote control of the base station.

For example: A conventional base station with two transmit frequencies and two receive frequencies with Channel Guard enable/disable capabilities. The station configuration and channel programming might look something like the following tables.
