Today at 09:44, the COIRS radio system experienced a 5 minute outage after a core switch at the Avery Road prime site experienced and automated, unexpected reboot.
B&C Communications has been notified and is investigating why the system went off the air and not into site trunking. As of 09:49, the system was back in service.
At approximately 11:15 today, contractors working in the area of Darby High School struck the fiber optic cable that connects the Hilliard Darby tower site for COIRS. Until the fiber can be repaired, the Darby tower will be off line. Responders operating in the Hilliard area will experience decreased in-building coverage. FiberTech, the provided of the fiber connection, has been notified and has a crew enroute to make repairs. There is currently no ETA on that repair. Updates will be posted as they are received.
For any questions, please contact Jay Somerville or the NRECC supervisor.
At 12;45, connectivity through XO was restored and the system is back in wide area trunking. All units can return to normal talk-groups.
The COIRS south simulcast went into site trunking today at approximately 10:25. The problem is with site connectivity involving XO Communications leased lines. XO reports they have a wide area outage affecting multiple customers. At this time, they do not have an ETA on resolution. All users of the south simulcast should switch to their “2” talkgroups to operate in site trunking.
A full service notice will be posted.
15:10 – RESOLVED: Huntley Road tower is now back in service. XO completed repairs
08:00 ORIGINAL: The Huntley Road tower site is off line. It appears there is a problem with the XO network lines leading to the site. A service ticket has been submitted with XO and a technician will be dispatched to investigate. Users may see some degraded in building coverage in the Worthington area during this outage. A full service message will be posted when the problem is repaired.
14:15 UPDATE: The system has been restored to full service. Connectivity was restored and the routers restarted bringing the system back into wide area trunking.
13:17 ORIGINAL: The COIRS south simulcast is currently in site trunking due to a problem with the tower connectivity circuits provided by XO Communications. Roaming has been turned off and mobiles/portables can function normally. Dispatchers will need to use back up radios until the problem is resolved.
A full service message will be sent when service is restored.
On Friday 11/06 at approximately 04:50hrs, the south simulcast went into a Failsoft condition for all users. Failsoft is a condition where the channels stop trunking and the system becomes a 7 channel conventional radio system. B&C Communications responded to the incident to discover a failure of the GPS receiver at the Avery Road site. The GPS is used to ensure all sites are synchronized. When this unit failed, trunking stopped. They quickly replaced the GPS unit with one of the on-site spares and the system was back in full service by 06:30am.
During the time the system was in Failsoft, users were still able to communicate by voice without interruption just as the system is designed.
If you have any questions about this incident, or need more information on the function of Failsoft, please contact Patrick Brandt or Jay Somerville.
