3. Frequency
The system can operate with different types of ODUs according to the RF band and
to the channel arrangement. There are ODUs that can manage only one shifter or
several predefined shifters.
In the Shifter field, select the suitable shifter.
In the Tx frequency field, enter the suitable Tx frequency (the Rx frequency is
automatically calculated by using the entered Tx frequency and the shifter).
The Rx frequency field will displays the calculated Rx frequency, but, by selecting
the Allow Rx Frequency Tuning check box this frequency can be changed in ±+5
MHz increments to implement the “Exotic” shifter configuration, if required.
4. Tx Mute
To mute the transmitter, select the Mute check box.
5. Transmit Power Control Mode
Select the Mode: RTPC or ATPC.
6. RTPC settings
• Tx power without Adaptive Modulation
If the ATPC is disabled, the Tx Power field is available. The Tx Power range is
displayed in the screen.
In this field, enter the new value within the allowed transmitted power range.
• Tx Power with Adaptive Modulation
Warning: If the changes increase the current radio bandwidth, the warning message
(Figure 4.55) will be raised to the operator. The new setting must be validated with
Alcatel-Lucent.
Note: For an MPR-e in a 1+1HSB configuration in Single NE mode with 7705 SAR, in order
to mute the entire mw-link a "TX-Mute" command shall be applied to both Main and Spare
radios.
