The MPSCS will be upgrading the microwave link between tower sites 1102 and 1104 located in Lansing (Ingham County) on April 26th. This work will require an eight-hour site outage at 1104 which will disconnect all registered portable and mobile subscribers from the site. Surrounding RF sites will provide coverage for mobile subscribers while portable subscribers may experience limited coverage.
To allow for issues such as system usage, dispatch emergencies, and weather events (fading), the window for completing this work is scheduled as follows:
1104 - 4/26/2021 from 8AM (0800) to 4PM (1600)
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.
