applets from the file system to a managing system.

used for loading software, configuration data and other large volume data.

7.4 GUI

GUI applications are web based (HTML and Java applets) and run in a standard

web browser. Two general types exist:

• Workflow oriented wizards, for example, for node expansion, initial

7.5 VMI

The VMI consists of:

• Visual indicators

• Switches and buttons

• Incoming external power

• External alarms and output

• Connectors, cables and screws

Visual Indicators

Each unit or board in the RBS is equipped with Light Emitting Diodes (LEDs):

red ones for fault indication and green ones for indication of operation.

Additionally, boards with a processor are equipped with a yellow LED for traffic

indication. All LEDs light simultaneously for one second when the power

is switched on.

Switches and buttons
