Site Trunking Event – Sunday 11/27/16

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.

Dublin Key Staff Radios

Key Staff TemplateStarting Monday 11/14, we will begin reprogramming the XTS-2500 radios that city staff have, with the exception of police.

These radios are mostly in use by crew leaders and supervisors/management staff.

If someone has one of these radios, they can drop them off on Monday at the service center between the hours of 1000-1400 or Tuesday and Wednesday between the hours of 1000-1400 at NRECC.

Information and updates will be found here.

Key Staff Template

Post Migration

On Monday 10/24, a meeting was held at NRECC to discuss the post migration template.

Present were Paul Richmond and Kris Harris (NRECC), Captain Pat Mulligan (Worthington Fire), Chief Mark Kidd (Pleasant Valley Fire) and Lieutenant George Sorge (NTFD). Lieutenant Kevan Redman (WTFD) was away at a meeting.

A tentative template was agreed on that will serve all agencies.

Columbus Fire went back to the drawing board and made revisions to their template, which is the base for ours. Our standardized template will be posted later this week when the Columbus fire revisions are included.

If you have any questions, please contact Paul Richmond.

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
