Step 3: Set the link identification number

2. Select the link idyou want in therange 0 to 15.

The link identificationnumber is a number inthe range 0 to 15 theoperator selects throughthe LCT to identify in aunique way a linkbetween a local and aremote IDR-C. The linkidentification numberis extremely useful incases of multiple linksexisting between twostations as it preventsthe stations fromdemodulating databelonging to some otherlink if , by mistake, thestations lock into thefrequency of this link.

1. Click REMOTE A.

3. Click.

4. Click LOCAL A and repeat steps2 and 3 to set the same id.

5. Click Enable so that, in case the linkid of the remote IDR-C is other than thelink id of the local IDR-C, an AIS alarm isenabled at the tributaries outputs. Theled beside the Enable button becomesyellow.


Step 4: Save the configuration you made

Configuring the IDR-C – Step 5 & 6

Step 5: Repeat steps 1 to 4 for the remote station

Step 6: Align the antennas of the two stations


Step 7: After the establishment of the link between the two stations, proceed to theoptimization of the link to achieve max RSSI level

To achieve reliable transmission in a microwave link, the transmitted power plus thegain of the transmitter and receiver antennas should exceed the attenuation at thetransmission path and the sensitivity of the receiver. The attenuation at thetransmission path is given in the following formula:

A=92.4+20logD+20logF

A is the attenuation at the transmission path in dBD is the distance between the antennas in kmF is the frequency of the microwave signal in GHz


Check the receptionlevel in the Rx In

box.

To optimize the link, while performing minor horizontal and vertical movements of theantenna, open the ODU tabbed sheet and check the reception level in the Rx In box in theRadio Measurements group box.

Prerequisites: If you use the LCT to observe the reception level or the RSSI, you will needanother person to move the antenna.
