Chapter4. Eclipse Edge Configuration and Diagnostics
Configuration Procedure:
1. From the Plug-ins screen, select the Link module.
2. Dual ODU Protection. Click to select. Both ODUs are identically configured for
capacity, bandwidth and path settings.
• When both ODUs are connected, the Link module will display two ODUs,
regardless of the Dual ODU Protection setting. However there will be a
configuration not supported alarm until protection is selected and sent.
• For hot-standby single antenna operation a coupler is required. Refer to Coupler
Losses on page 40.
• Both ODUs must have the same diplexer option (same ODU part number).
• Capacity and frequency settings apply to both ODUs.
• For more information on dual ODU protected operation, refer to Edge Dual
ODU Protection Operation and Rules on page 39.
3. Capacity. Click Capacity to view and select an option from the submenu.
• The options shown are those permitted by IDUspe and ODU300spe.
4. Bandwidth / Modulation. This is fixed for the selected capacity.
5. Frequency. The displayed Tx Frequency Range, Tx high or Tx low, and the choices
of Tx/Rx spacing are read from the installed ODU(s). Entries outside the allowable
ranges are not accepted (shown as red text).
• The Tx/Rx spacing can only be selected from the Tx/Rx menu.
• Setting Tx frequency and T/R spacing automatically sets the Rx frequency. Tx
frequency is direct entered in 250 kHz steps. Values outside the 250 kHz step
points are not accepted.
• Tx/Rx spacing shows as a +ve MHz value for a Tx low ODU and as -ve value for
Tx high.
• Rx frequency can be direct entered if preferred, whereupon the Tx frequency is set
automatically based on the selected Tx/Rx spacing. Again, such selection is only
be permitted within the constraints of the allowable frequency steps and Tx/Rx
Spacing.
The allowable minimum and maximum Tx and Rx frequency settings
are modified according to the Bandwidth/Modulation selection such
that band edges and spacings are not infringed.
6. Enter a Tx Power value, which can be set in 0.1 dB steps
OR
Enable ATPC by clicking the Use Automatic Power Control checkbox. The
additional ATPC fields displayed are detailed in ATPC Guidelines on page 40.
The
Detected Tx Power displays the measured Tx power at the ODU, for direct
comparison with the set Tx Power value. Accuracy is +/- 2 dB over temperature and
range.
7. Factory Tx Mute is a one-time action. Removing the mute will remove all
reference to this feature. Its purpose is to ensure that on initial power-on there is
no transmitted signal until the ex-factory settings for frequency and Tx power are
checked, and if necessary, reset.
