Front Panel Operation	MN/CDMQx.IOM

5.2Left-Hand Display Area

The left side of the display (or slot screen) efficiently indicates what is in the four plug-in slots and which slot is currently being addressed.

Four ungrouped plug-ins are displayed as in this example:

TX	TX		(right	hand	display	area)
<RX>	RX		(right	hand	display	area)

This display indicates modulators in the top slots, and demodulators in the bottom. The locations of the four indicators line up with the location of the four slots when viewed from the back of the chassis. The left hand TX on the display corresponds with the top left slot in the chassis when viewed from the back. An empty slot is left blank.

The left RX on the example display is highlighted. This is the selected slot. All monitor functions (including the front panel LEDs) reflect the status of this slot. All parameters selected from the menu tree while this slot is selected apply either to this slot or to common functions. The menus for common functions appear redundantly in all four slots. To change slots, move the cursor to the desired slot, and press enter.

The designator for a plug-in device with an unmasked failure has an F suffix:

TX	TXF		(right	hand	display	area)
<RX>	RX		(right	hand	display	area)

In this example, the upper right transmitter has a fault. (View the fault using Monitor, Alarms, etc).

5.2.1Modems

A modulator in a top slot can be grouped with a demodulator in the slot directly below it to form a modem:

TX	<MD>		(right	hand	display	area)
RX			(right	hand	display	area)

The example indicates a configuration in the right hand slots (when viewed from the back of the chassis) grouped together to form a modem. Selecting the slots is the same as a basic configuration except that the blank area below the MD are not be selectable. When the modem is selected, the menus will display modulator and demodulator functions, and the software will select the appropriate plug-in for the command.
