Guide to FOX Splicer Operations Slide 2 Sun Transit Outage During sun transit periods, FOX splits the A&B 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. Slide 3 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 GUIhttp://www.hdrollout.com Sun Transit Outage Slide 4 Slide 5 Slide 6 When the 1 st 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 A&B 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 Slide 7 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: 1.Go to Station Engineer GUI and double-click the Normalize DCM B button 2.And then Splice to Network 3.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 Sun Transit Outage 1 2 Slide 8 1 Slide 9 2 Slide 10 When the 2 nd 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 A&B 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. Slide 11 Sun Transit Outage Wait 3 sec, then double-click Slide 12 Sun Transit Outage The sun has passed, and FOX Receiver A recovers: Network A feed will come back causing: Net A to turn back to green DCM B to turn back to normal DCM A to turn yellow Then: 1.Go to Station Engineer GUI and double-click the Normalize DCM A button 1 Slide 13 Sun Transit Outage Slide 14 1 Slide 15 Slide 16 The ROSA GUI should be all clear as shown below: Otherwise, contact FOX TOC Slide 17 Sun Transit Outage 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
