Network Maintenance Alert – Nov 28th

XO Communications has notified COIRS that they will be performing critical network maintenance on the circuits that support our radio system on Tuesday 11/28 between 00:01 and 06:00. There will be multiple connectivity interruptions  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. Although the consoles will remain connected, they will not be usable on COIRS talk-groups during site trunking & walkies must be used.

Field units will receive the “SITE TRUNKING” notice on their radios, but can continue to operate on their normal talk-groups. System roaming will be turned off during this time so that units won’t get separated onto the Delaware side of the system. Delaware County users will not be affected during this outage.

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