Changing Mode will temporarily interrupt traffic. The Mode setting
must match at each end. Adjust the far-end radio first, and then the near-
end radio. Changing Mode changes the radio’s threshold, carrier-to-
interference ratio, and also may have impact on the Radio Transmit
Power. A lower mode has better threshold performance and carrier-to-
interference ratio, and in some cases, higher output power, therefore if
changing to a higher mode (for example, from Mode 1 to Mode 2), there is
an opportunity that the link may be lost and unrecoverable through GUI
control. Check the available fade margin and interference profile, and
determine if the impact to RF performance is sufficient to maintain the
link and desired performance. If the link is lost due to increasing the Mode
parameter, travel to the radio location(s) may be required to reset the
value.
• Set the RF Frequency parameter to the designed point. The value of this setting is
determined in the design/engineering stage. RF Frequency must match at both ends of
the link. It may be critical to set RF Frequency with respect to the local RF noise and
interference profiles, and/or in relation to any multi-link network design.
The frequency selection section includes the ability to select from either the complete
list of frequencies (“All”) that can be tuned for the selected band and bandwidth, or a
pre-selected list of non-overlapping center frequencies (“Preferred”) that Exalt
determined provides the most flexible collocation opportunities for large networks of
Exalt radios
For the EX-5i families, the frequency selection section includes a band selection
button that must be enabled for the frequency band of operation for which the link
was engineered. In some cases, some bands may not be selectable due to regulatory
constraints.
Changing RF Frequency will temporarily interrupt traffic. The RF
Frequency parameter setting must match at each end. Adjust the far-
end radio first, and then the near-end radio. If the RF Frequency parameter
is changed to a frequency with interference, the link may be lost and
unrecoverable through GUI control. If the link is lost due to changing the
RF Frequency parameter, travel to the radio location(s) may be required to
reset the value.
• Set the Endpoint Identifier so that one end of the link is set to Radio A and the
opposite end set to Radio B. In single-link networks, it is unimportant which
end is designated A or B. In multi-link networks, however, it may be
important to orient the links so that at any collocation site (where there are
multiple radios of the same type at the same site), all radios are set to the same
Endpoint Identifier (A or B). See Link Orientation and Synchronization
on
page 34.
Changing Endpoint Identifier parameter requires a reboot of the radio to
take effect. The reboot temporarily interrupts traffic.
