4. Click (tick) Commissioned for the traffic-carrying tribs.
A commissioned selection supports alarm conditions for the unexpected loss
or presence of traffic:
• For unprotected DACs a commissioned selection has no effect on traffic.
• For protected DACs LOS is a switching condition.
5. To enter a tributary name by clicking in the Name field and typing. Entering
a name is optional.
Names entered are also displayed in the System/Controls screen for the same
DAC/Tributary.
When entering data in the Tributary Lines field (steps 3 to 6 below) the Select All
and Fill Selection tabs can be used to quickly populate lines with identical
settings.
Where all tribs require the same settings, complete data entry for the first line
then click Select All to highlight all trib lines, followed by Fill Selection.
Alternatively use standard Windows procedures (Ctrl+Click, Shift+Click or drag)
to highlight just the lines required, then click Fill Selection.
Fill Selection populates all highlighted lines with data from the top-most
highlighted line.
Trib uncommissioned Trib Commissioned
• LOS alarms are suppressed.
• AIS alarms are suppressed.
• Received traffic causes an
uncommissioned traffic alarm.
• LOS alarms are raised if LOS is
detected. Front panel Status LED
indicates red for an LOS alarm.
• AIS alarms are raised if AIS is
detected.
For protected DACs and IDUs LOS on any trib interface is a switching condition.
Ensure all traffic-carrying tribs are commissioned (commissioned tick-box for
relevant trib(s) is ticked).
So that invalid alarms are not raised, ensure all tribs not carrying traffic are not
commissioned (not ticked).
It is recommended the trib name has the same name as its circuit, which is
entered in the Circuits screen, or include a reference to it in the circuit name, so
there is an easy association of trib and circuit names when setting a Circuit
Loopback for a trib BER test.
