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.

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.
