Warning : The lower center frequency attribute must be configured to the same value for both
the master and slave. Failure to do so will cause the wireless link to fail re-establishment. The
only way to recover from this situation is to modify the Lower Center Frequency attribute so
that they are identical on both the master and slave unit.
Fixed Transmit Frequency, Fixed Receive Frequency: The software for the PTP 400
Series Bridge allows a user to optionally fix transmit and receive frequencies for a wireless
link. The settings must be compatible at each end of the link. Once configured the spectrum
management software will not attempt to move the wireless link to a channel with lower co-
channel or adjacent channel interference. Therefore this mode of operation is only
recommended for deployments where the installer has a good understanding of the prevailing
interference environment.
Warning: Ensure that the Rx and Tx frequencies are correct.
Figure 45 shows a sample fixed frequency configuration. See section 5 “General
Considerations” for further information.
