**System Maintenance Alert – Friday Night 02/19**

XO Communications notified COIRS that they will be performing emergency updates to the network switches that support our radio system between Friday 02/19 @ 23:00  and Saturday 02/20 @ 06:00. There will be at least one connectivity interruption of up to 2 to 3 hours during this time frame that will cause the system to go into site trunking. Dispatchers will need to be ready to use back up radios/walkies during this outage. Field units may receive the “SITE TRUNKING” notice on their radios, but can continue to operate on their normal talk-groups.

If you have any questions/concerns about the outages, please contact Jay Somerville
