Note: 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.
Note: 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 26.
Note: Changing Endpoint Identifier parameter requires a reboot of the
radio to take effect. The reboot temporarily interrupts traffic.
