9932R ATCO Chard - 72s Radio - TPR/RTU
Ref #: 272525
Dates: Dec 9 @ 08:00 – Dec 10 @ 17:30
Scope: Radio replacement. Loss of visibility of a number of sites
for the duration. Clean up 72s RTU configuration on Oct 5.

Comments/Scope Clarification:
On Oct 5 @ 08:00 – 17:00 = 72s RTU configuration update – needs to be done prior to radio outage. 2 or 3 short (15 minute) outages in the timeframe listed.
On Oct 6 @ 08:00 – Oct 7 @ 17:30 – Radio replacement.
Loss of 9L930 & 9L990 A&B TPR for the duration. Stability study completed.
AltaLink is looking at re-routing the affected sites, but if the re-route is not successful (bandwidth issue) there is a possibility that the following sites will lose visibility for the duration.
72s Leismer, 762s Conklin, 539s Sunday Creek, 167s Ipiatik, 183s Underwood, 170s Pike, 154s Black Spruce, 698s Jackfish, 651s Kirby, 818s Winefred, 723s Christina Lake, 852s Roundhill.
Priority will be given to 762s, 539s, 72s if the bandwidth issue arises.
Arrangements made with 539s and 762s to go to manual reporting if the bandwidth issue arises.
There is also a setting change on 7L114 required.
