All COIRS System Users: 

OARnet has notified us they will be doing upgrades to the network switches that support our system on Thursday  06/07 (Wednesday night/Thursday morning) starting at 00:01 and lasting until 06:00. There will be temporary outages during these times that will cause the consoles to lose connection and the system to go into site trunking. The outages should last no more than 15 minutes at a time and may occur up to 5 times. Dispatchers will need to use back up radios/walkies during these outages. Field units will receive the "SITE TRUNKING" notice on their radios, but can continue to operate on their normal talk-groups. 

The number of outages needed to complete the upgrade are unknown and may not affect all circuits.
