Under normal circumstances the unit will freely transition between modulation modes
to suit the wireless conditions. The "Single Payload Lock" indicates that the ODU will
prevent transitions from Single Payload modes to the higher Dual Payload modes in
order to avoid loss of telecoms data. This field appears where such a transition would
pass through modes which cannot carry telecoms data. This may be because, in order
to control latency, the lowest modulation mode has been set to a higher Single Payload
mode.
In the absence of the Single Payload Lock the wireless will transition to the faster Dual
Payload modes as soon as the conditions are appropriate. With the lock enabled, the
wireless will dwell in slower Single Payload modes whenever there are operational
telecoms links (operational links are shown as "Up" in the telecoms channel field
described above). When the lock is actively preventing transitions, the value displayed
changes from "Enabled" to "Applied".
TDD Synchronization
Displays the TDD Synchronization status for the link. For more information, refer to
TDD synchronization status on
page 6-16.
Refresh Page Period
The Status page refreshes automatically according to the setting entered here (in
seconds). This attribute is only displayed when the user is logged on as System
Administrator.
Wireless Link Status
As the attribute name suggests it displays the current status of the wireless link. A
state of ‘Up’ on a green background indicates that a point-to-point link is established.
A state of ‘Down’ on a red background indicates that the wireless link is not
established.
Maximum Transmit Power
The maximum transmit power that the local wireless unit is permitted to use to sustain
a link.
Remote Maximum Transmit Power
The maximum transmit power that the remote wireless unit is permitted to use to
sustain a link.
Transmit Power
Transmit power histogram is expressed in dBm and presented as: max, mean, min, and
latest. The max, min and latest are true instantaneous measurements; the mean is the
mean of a set of one second means. See Histogram data on
page 6-18.
