•
Bandwidth must be set to the designed level. The value of this setting should have
been determined in the design/engineering stage. The Bandwidth setting must also
match at both ends of the link. The Bandwidth setting directly relates to the capacity,
latency and the number of TDM circuits that can be supported. It may also be critical
to set this with respect to the local RF noise and interference profile, and/or in relation
to any multi-link network design.
Changing Bandwidth will temporarily interrupt traffic
.
The Bandwidth setting
must match at each end
– adjust the far-end radio first, then the near-end radio.
Changing Bandwidth will change the radio’s threshold. A narrower bandwidth has
better threshold performance, therefore if changing to a wider bandwidth, there is an
opportunity that
the link may be lost and unrecoverable
through GUI control. Check
the available fade margin and determine if the impact to threshold will be sufficient to
maintain the link and the desired performance. If the link is lost due to increasing
Bandwidth, travel to the radio location(s) may be required to reset the value.
•
RF Frequency must be set to the designed point. The value of this setting should have
been determined in the design/engineering stage. The RF Frequency must also match
at both ends of the link. It may be critical to set the RF Frequency with respect to the
local RF noise and interference profile, and/or in relation to any multi-link network
design.
Changing RF Frequency will temporarily interrupt traffic
.
The RF Frequency
setting must match at each end
– adjust the far-end radio first, then the near-end
radio. If the RF Frequency is changed to a frequency that has interference, there is an
opportunity that
the link may be lost and unrecoverable
through GUI control. If the
link is lost due to changing RF Frequency, travel to the radio location(s) may be
required to reset the value.
•
Endpoint Identifier
must be set 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. However, in multi-link networks, it may be important to orient the
links so that, at any co-location site (where there are multiple radios of the same type
at the same site), all radios have the same Endpoint Identifier (all A or all B). See
section 2.5 for more information.
Changing Endpoint Identifier initiates a reboot of the radio. The reboot will
temporarily interrupt traffic.
•
Link Distance
must be set to the range that is equal to or greater than the actual
link distance
. The value of this setting should have been determined in the
design/engineering stage.
Changing Link Distance will temporarily interrupt traffic
.
The Link Distance
setting must match at each end and must not be less than the actual link distance
– adjust the far-end radio first, then the near-end radio. If the Link Distance is changed
