Bulletin 2021-02; Performing work at tower sites 1106 and 1104 (Ingham County)

The MPSCS in conjunction with Motorola Solutions Inc (MSI) will be performing work at tower sites 1106 and 1104 located in Lansing (Ingham County) on April 5th and 10th.  This work will require a four-hour site outage 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:

1106 - 0830AM (0830) to 12:30PM (1230) on Monday 4/5/2021

1104 - 0830AM (0830) to 12:30PM (1230) on Saturday 4/10/2021

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.
