2.2 Installation in the Densité frame
The DDA-1133 and its associated connector rear panel must be mounted in a DENSITÉ-2 or DENSITÉ-3-series
frame. It is not necessary to switch off the frame’s power when installing or removing the card. See the appropriate
DENSITÉ Frame manual for detailed instructions for installing cards and their associated rear panels.
•The rear panel must be installed first, before the card is inserted into the frame.
•When used with a dual-slot rear panel, the DDA-1133 must be installed in the right-most of the two slots
covered by the panel in order to mate with the panel’s connectors. If it is placed in the wrong slot, the front
panel LED will flash red. Move the card to other slot for correct operation. No damage will result to the card if
this occurs.
3 Operation
3.1 Card-Edge Controls and Indicators – Status LED
The status monitor LED is located on the front card-edge of the DDA-1133, and is visible through the front access
door of the DENSITÉ frame. This multi-color LED indicates the status of the DDA-1133 by color, and by
flashing/steady illumination.
The chart shows how the various error conditions that can be flagged on the DDA-1133 affect the LED status.
•If a cell is gray, the error condition cannot cause the LED to assume that status
•If more than one LED status is possible for a particular error condition, the status is configurable.
See Section 3.2.2 for details.
•The factory default status is shown by a 
The LED will always show the most severe detected error status that it is configured to display, and in the chart error
severity increases from left to right, with green representing no error/disabled, and flashing red the most severe error.

If the LED is Flashing Yellow, it means that the card is selected for local control using the Densité frame’s control
panel. See Section 3.2 for details.
When the DDA-1133 is installed in the Densité 3+ FR4 frame or the GV Node, the card status is shown on the touch-
screen display’s home page by the colored outline of the DDA-1133 access button.
3.2 Local control using the Densité frame control panel
There are two types of local control panel:
Panel type Frame models Appearance
Physical Densité-2
Densité-3
Densité-3+FR1
Touch screen Densité 3+FR4
GV Node
The local control panel is fastened to the front of the controller card.
•The physical panel is accessed by opening the front door of the frame.
•The touch screen panel is accessed through an aperture in the frame door.
The panel consists of a display capable of displaying two lines of text, each 16 characters in length, and four
pushbuttons. The functionality of the pushbuttons is as follows:
[+] [–] Used for menu navigation and value modification
[SEL] Gives access to the next menu level. When a parameter value is shown, pushing this button once
enables modification of the value using the [+] and [–] buttons; a second push confirms the new value
[ESC] Cancels the effect of parameter value changes that have not been confirmed; pushing [ESC] causes the
parameter to revert to its former value.
Pushing [ESC] moves the user back up to the previous menu level. At the main menu, [ESC] does not
exit the menu system. To exit, re-push the [SEL] button for the card being controlled.
If no controls are operated for 30 seconds, the controller reverts to its normal standby status, and the selected card’s
STATUS reverts to its normal operating mode.
To assign the local control panel to the DDA-1133:
•Physical Panel: Push the SELECT button on the DDA-1133 card edge (see Section 1.4).

Use the control panel buttons to navigate through the menu, as described above. The complete menu structure is
shown below.
3.2.1 Menu for local control
Using the menu, the user can:
oDisplay the error status if any is present
oAdjust the No Signal Delay and Signal Threshold to set the conditions of a No Signal alarm. A signal absence
is declared when the level is lower than the threshold during the selected delay.
oAdjust the correction applied to the input signal:
AUTO A START will initiate an automatic sequence, indicated by PROCESS. When the input status
becomes correct it will stop and SUCCESS will be displayed. FAIL will be displayed to indicate that
no correction has been found that will yield to a correct input status.
LENGTH This command allows a manual adjustment of the correction applied to the input signal. The input
status is displayed at the same time to ease the setting.
oEnable or disable the internal Reclocker..
oConfigure the different alarms, setting the alarm level (color displayed on the front panel status LED, and
severity reported to the frame controller) and selecting whether the alarm is to be reported on the frame’s GPI
interface.
