SHAPING THE FUTURE OF SATELLITE COMMUNICATIONS
The next sequence is followed on the remote site. (refer to Figure 111)
When the demodulator/modem on the remote site looses connection (unlock) with
the current frequency a switch is performed to the other frequency . When the
demod is not locked within the switch delay time the second frequency is tried.
This sequence continues until the demod is locked.
Figure 111 - Flow
When the demod is locked on the new carrier it is important that:
1. The setting carrier switching is set to disable;
2. The configuration is saved in config (0). (Refer to boot
configuration on page 177)
During the switchover alarms will occur. This provides the real
state of the device.
