Indicate the current status of the telecoms channels.
Channels which are disabled during installation are marked
as such. Correctly operating channels display "Up" on a green
background, but alarm conditions (described in
alarm display on page 7-7) have a red background.
The Telecoms Latency value, displayed in microseconds, is
determined when the wireless link starts and will remain the
same for a given wireless configuration. Section
circuits on page 1-41 describes methods for reducing
telecoms latency on links which support high data rate
modulation modes.
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".
