TROUBLESHOOTING
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.

Sun Transit Outage

• 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

TROUBLESHOOTING
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

TROUBLESHOOTING
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
