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".
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 Section
8.2.1 “Histogram Data”.
Rec
eive Power: Receive 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 Section 8.2.1 “Histogram Data”.
