Sun Transit Outage
During sun transit periods, FOX splits the AB
radios to different satellites, thus assuring a
network signal continuity at all times. We
arrange for the B-radio to be transited first. 15
mins later, the A-radio is transited. Start the
transits with the A radio and A DCM switched to
air. NOTE Operator intervention is required to
remain on air through these transits. If you are
able to switch your B-chain (B-radio and B-DCM)
to air, see slide 7. If not, see slide 10 for an
alternative.

- Normal State
- Under normal conditions, the ROSA GUI should look
like those displayed below - In the following slides we will discuss
step-by-step how the splicer will react to the
sun transit outage - NOTE Make sure the ROSA GUI is available and
running prior to the start of FOX Network
operations. See the FOX Operational Guide,
available on the FOX Splicer Website
(http//www.hdrollout.com ) to setup and start
the ROSA GUI

Sun Transit Outage
- When the 1st satellite is affected by the sun,
the B Radio output will be interrupted - This will impact DCM B, but DCM A is unaffected.
Further, you will see the following on the ROSA
GUI - Net B turns red
- DCM AB both turn red
- Both Network and Local tallies light
simultaneously (DCM A is now on Network, and DCM
B failed over to Local) - At this point, do nothing and wait until the sun
has passed and Receiver B recovers

Sun Transit Outage
- FOX Receiver B recovers
- Network B feed will come back causing
- Net B to turn back to green
- DCM A to turn back to normal
- DCM B to turn yellow
- Then
- Go to Station Engineer GUI and double-click the
Normalize DCM B button - And then Splice to Network
- If the station is configured appropriately,
select B-radio and B-DCM to air before next
transit starts - IF NOT, SEE SLIDE 10 FOR AN
ALTERNATIVE METHOD

- When the 2nd satellite is affected by the sun,
the A Radio output will be interrupted - This will impact DCM A, but DCM B is unaffected.
Further, you will see the following on the ROSA
GUI - Net A turns red
- DCM AB both turn red
- Both Network and Local tallies light
simultaneously (DCM B is now on Network, and DCM
A failed over to Local) - NOTE The splicer output will failover to Local
during this transit - Wait 5-7 seconds, then trigger Splice to Network.
This will restore the feed.

- Other Possible Issues
- Situations may arise where the outage can cause
other issues or failures, in this case call the
TOC (310-369-6116) - Crossover A or B switch tripped (Output Status
tally orange) - Tx A or B tripped (Output Status tally red)
- DCM A or B turns yellow or red, and will not
normalize
