AirMux-200 Installation and Operation Manual Chapter 2 Installation and Setup

Installation and Setup 2-7

To align the ODUs using the AirMux Manager:

1. Connect power to the IDUs.

Do not stand in front of a live radio terminal.

2. Turn the local ODU in the direction of the remote ODU.

3. At the remote site, turn the ODU to face the local ODU. (Align

visually or by using a map and a compass).

4. Repeat step 3 for the local ODU to complete the installation

procedure.

5. Make sure that the management station is properly connected to

the same LAN as the IDU, and the AirMux Manager application is

running.

6. In the Main menu, click Monitor.

Once the wireless link is established between the local and

remote units, the Link Status indication bar in the middle of the

Main menu turns green. In addition, Radio Link - Sync message

appears in the logger at the bottom of the Main menu.

7. Check the radio signal strength (RSS) and sound-to-noise ratio

(SNR) in the Main menu. Rotate the local ODU until the best RSS is

found (better than -88 dBm). The SNR should be at least 9 dB.

Monitor these parameters for about 15 minutes to verify stability.

Try to achieve the best possible RSS and SNR values.

8. After achieving the best RSS and SNR levels, permanently attach the

ODU to the mast. Refer to Appendix B for the ODU mounting

instructions.

Connecting the User Equipment

The IDU is a standalone desktop, wall-mounted or rack-installed unit.

Figure 2-2 illustrates a typical rear panel of the IDU.

To connect user equipment to the IDU:

1. Connect a user mux or PBX to the IDU rear panel RJ-45 port

designated Trunk. Refer to Appendix A for the connector pinout.
