Avery Tower Work Today

Crews will be placing the antenna pod back onto the top of the Avery Road water tower now that painting work has been completed. The Avery site will be taken off line starting at 8am. It is expected that the pod will be lifted into place by 1pm and the site back on line by 6pm tonight. During this outage, users may experience diminished in building coverage in the west and southwest areas of Dublin.

Scheduled System Outage - Dub/Wor Simulcast

The Dub/Wor simulcast side of the system will go down on Thursday 10/21 @ 05:00hrs for system maintenance. Motorola will be replacing the TenSr power supply cages to address false alarms being sent by MOSCAD. The outage is expected to last no more than 90 minutes.

User agencies will be notified prior to the outage and will need to implement their back up plans accordingly. A full service message will be transmitted once the work is complete.

If you have any questions, please contact Jay Somerville.

MARCS Agreements

Member Agencies:

You more than likely received an e-mail from Andrea Payne from Ohio MARCS asking that you execute a users agreement to cover the radios you received from Columbus via one of the three grant programs administered by Franklin County. The agreement you were sent was not the correct one. None of you are full time users of the MARCS system. Please DO NOT not execute the agreement. 

Each of you are currently Local Emergency Use Only (LEUO) users on the MARCS system. The MARCS ID you have in each of your radios has already been paid for and you would only be billed by MARCS if you use their system for more than just emergency use. 

We have talked with MARCS about this issue on behalf of the COIRS members. In the next few days, we will send each of you a completed MARCS LEUO agreement to sign. This will ensure all of our member agencies are current with their MARCS agreements. Once we receive all of the signed agreements back, we will submit them and a complete radio inventory to MARCS on behalf of the COIRS member agencies.  

Your COIRS Technical Committee is on top of the issue and will see to it that interoperability will not be adversely affected.

If you have any questions, please contact Jay Somerville.

Technical Committee Meeting Agenda

The COIRS Technical Committee will meet today at 1:00pm at the Worthington Police headquarters building at 6665 Worthington-Galena Road.

Temporary Roaming Plan In Effect

Effective Saturday 09/18, talk-group roaming between systems will be limited to EMS talk-groups only. This change is to help reduce the loading on the Delaware side of the system during the Delaware County Fair. These restrictions will be in effect until Monday 09/27.

If you have any questions or emergency roaming needs, please contact Patrick Brandt to arrange for changes.

System Update

At 5:25 am today, the system was restored to full service using the alternate fiber route to bypass the damaged cable. Delaware County's fiber vendor will be working today to repair the primary cable. Once that work is complete, the system will be moved back over to the primary fiber. This move back may case a brief return to site trunking, lasting no more than 5 minutes. Users will be informed prior to the move.

More details about this system event will be gathered and an after action report completed. That report will be shared with all user agencies.

Dublin/Worthington in Site Trunking

At approximately 23:55 on Tuesday 09/14, the Dublin/Worthington side of the system went into site trunking. A check of the system revealed a fiber optic cable cut in front of the Delaware 9-1-1 center that has disrupted the connectivity to the Dub/Wor side of the system.

At this time, the Delaware County side of the radio system is NOT effected, although Delaware County mobile data users have lost connectivity as that traffic is carried on this same fiber run.

Crews are responding to make repairs to the cable. No ETA is yet available. Radio users on the Dub/Wor side of the system have the option of using the system in site trunking mode or going to their back up plans using alternate trunked radio systems such as MARCS or the Columbus 800MHz system. Consoles at the Dublin & Worthington dispatch centers will remain disconnected from the COIRS system until the cable is repaired. Updates will be posted as they become available.
