Hello, dear.

Setting ODU Transmit Frequency Attributes

The ODU transmit frequency attributes define the DOU transmit frequency and T/R spacing.

Prerequisites

  • You must be an NM user with NE operator authority or higher.

  • The IF boards and the ODUs to which the IF boards are connected must be added on the NE Panel.

Tools, Equipment, and Materials

U2000

Web LCT also supports this operation and the steps are the same as those on the U2000.

Procedure

  1. Select the ODU from the Object Tree in the NE Explorer. Choose Configuration > ODU Interface from the Function Tree.

  2. Click the Radio Frequency Attributes tab.

  3. Configure Transmit Frequency(MHz) and T/R Spacing(MHz) of the ODU.


    tt_rtn900_cfg_0155_fig01.png

    icon-note.gif NOTE:


  • The value of Transmit Frequency(MHz) must not be less than the sum of the minimum transmit frequency supported by the ODU and a half of the channel spacing, and must not be more than the difference between the maximum transmit frequency supported by the ODU and a half of the channel spacing.

  • The difference between the transmit frequencies at both ends of a radio link should be one T/R spacing.

  • If the ODU is a Tx high station, the transmit frequency is one T/R spacing higher than the receive frequency. If the ODU is a Tx low station, the transmit frequency is one T/R spacing lower than the receive frequency.

  • A valid T/R spacing value is determined by the ODU itself, and T/R Spacing(MHz) should be set according to the technical specifications of the ODU.

  • The T/R spacing of the ODU should be set to the same value at both ends of a radio link.

Click Apply.

Thanks!

Something going wrong. I change TX Frequency at both ends but I don`t see the changings of the actual values.

I don't quite understand what you mean, have the parameters not been set successfully?

I make TX Frequency 14711 instead 14580 (pic 1) and I make it 15131 instead 15000 (pic 2), but actual TX and RX Frequency doesn`t change.

Pic 1 and pic 2 are the diffrent ODUs which look at each other.
