Site Trunking Event – 08/02/16

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.

**System Maintenance Alert – TONIGHT**

XO Communications notified COIRS that they will be performing emergency updates to the network switches that support our radio system between Tuesday  (04/26) @ 23:45  and Wednesday (04/27) @ 06:00. There will be multiple connectivity interruptions 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. 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

Site Trunking Event

The COIRS simulcast is currently in site trunking (03/31 @ 22:00) Dispatchers should have walkies tuned to the talk groups in addition to the consoles to ensure all radio traffic is heard. The cause is a down XO circuit. XO repair has been notified.

Hilliard Darby tower goes live

towerMotorola engineers, along with staff from COIRS, completed the final checklist and officially brought the site up on the air this morning. This site is now bringing expanded area coverage and improved in building coverage in Hilliard, Norwich Twp and Brown Twp. The two channel expansion was also completed on all sites but will not be turned on until COIRS receives FCC approval.

**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.

Failsoft Event – Friday 11/06

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.

**System Maintenance Alert – Sunday 11/08**

how_fiber_optics_workDelaware County will be performing a fiber optic cable move that will affect our radio system on Sunday 11/08 between 8am and 10am. During this time there will be an outage 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.
