Bulletin 2021-10A; Correction to 8203 time window

 
The MPSCS will be upgrading router firmware throughout the network.  This work will affect specific site routers leading to site trunking events.  The listed ASR site routers below are expected to be down for 5 minutes to complete the upgrade.
 
To allow for issues such as system usage, dispatch emergencies, and weather events (fading), the window for completing this work is scheduled as follows:
 
*  Correction to 8203 time window
 
5403 (Berrien) - 6/29/2021 from 8AM (0800) to 10AM (1000)
2504 (Northville) - 6/29/2021 from 10AM (1000) to 12PM (1200)

8807 (Covington) - 6/30/2021 from 1PM (1300) to 2PM (1400)
 
Dispatch centers are encouraged to review their backup plans and have them in place prior to the outage event. 
 
Please share this information with your staff and users of the system to minimize disruptions to your organizations.
 
If you have an active emergency prior to the scheduled outage time at a tower site, please contact the NCC and request they temporarily delay until the emergency has stabilized. If the site outage has started, the site will not return to wide trunking until the work has completed.
 
The MPSCS NCC may be contacted at (888) 554-4622 or (517) 333-5050 if you have a question regarding the operation of the MPSCS or need assistance preparing for this event.
