• Basic Knowledge• 1+1 HSB• 1+1 FD• 1+1 SD


Basic Knowledge• 1+1 Configuration

For RTN 620, the paired slots (slot5 and slot7) consist a 1+1 protection group; the paired slots (slot6 and slot8) consist another 1+1 protection group.

Slot 5 and slot 6 is main slot respectively.

For 1+1 HSB and SD application, It is only necessary to configure main IF board parameters.

For 1+1 FD application, It is necessary to configure main parameters and standby parameters respectively.

Application

ODU port insertion loss, db max:3.8 (38G:4.0).

with equal attenuation in both channels

Symmetrical Hybrid Coupler (3dB)

Main ODU port insertion loss, dB max:1.8 (38G: 2.0);Standby ODU port insertion loss, dB max: 7.2 (38G:7.4)

with one main channel and one standby channel.

Asymmetrical Hybrid Coupler(6dB)

Receive PowerDescriptionCoupler Type

• Hybrid Coupler with Waveguide Interface


Basic Knowledge• Trigger Conditions and Antenna Aligning

Alarms R_LOF,R_LOS,MW_LOF are the microwave link alarm.

While aligning antennas, the microwave link is not stable, will create these alarms.

In order to finish antennas aligning quickly, for 1+1 application, we suggest turn off the standby IF ODU-PWR switch at first, after antenna aligning finishing, turn on the standby IF ODU-PWR.
