UPDATE: 05/08 @ 16:30 The repair work is complete and the Huntley Road site is back on the air. _____________________________________________________
UPDATE: 05/08 @ 14:30 AT&T is working to repair the data line that was pulled down, causing the outage. Restoration time is expected to be no later than 20:00 tonight. ________________________________________________________
The Huntley Road tower site is currently off line due to a failure in connectivity. The provider has been notified and is working on a repair. A message will be sent when the site is back in full service.
Starting on Monday May 18th at 8am, technicians from Motorola will take the Hard Road tower site off line as part of the project to replace the equipment shelter building. The work is expected to last until the afternoon of Wednesday May 20th. During this period, this site will be off the air. Users in Dublin and along Riverside Drive will experience degraded walkie coverage, especially in medium to high density buildings in that immediate area. The backup talk-groups of COIRSLE and COIRSFD on the MARCS system will be available and monitored for backup communication, if needed.
A full service message will be sent when the work is complete.
At approximately 13:35 today, the COIRS system went into an unscheduled Site Trunking condition. The cause was electrical work taking place at the system master site that tripped a breaker unexpectedly. The power was restored and the system returned to normal at approximately 13:40. Site Trunking worked as designed and there was no interruption of service to subscribers. Dispatchers utilized back up radios during the event.
The next COIRS Governing Board meeting, set for April 17th, will be a virtual meeting, held via WEBEX and call in teleconference. In accordance with Ohio’s open meetings law, the board will accept public comment and questions during the meeting. Please contact Board Secretary Jay Somerville for an access code & instructions on how to join the meeting.
XO Communications is reporting a line down condition for the circuit that serves the Huntley Road tower site location. Users in that area will experience diminished in-building coverage during this outage.
Once repairs are complete, a full service message will be posted.
As part of our ongoing system maintenance program, Motorola will be performing an upgrade to the COIRS radio system starting Monday, March 18th . This first week of the upgrade will involve the tower sites and connectivity and be mostly transparent to the users. However, we are expecting to experience at least four “site trunking” events. These are scheduled for the following days/times:
Monday, 3/18 at 10:20
Tuesday, 3/19 at 08:40, 13:20 and 17:20
Each event will last approximately 10 minutes. Users will
receive a “SITE TRUNKING” notification on their display, but talk-groups should
continue to function normally and all sites will remain functional with no
expected change in coverage. Dispatch consoles will lose connectivity and
dispatchers will need to be prepared to use back up radios during these events.
As with any upgrade, the schedule can fluctuate. NRECC
and/or DELCOMM will announce over the radio, including LAW MUTUAL before
CS Lauren Yankanin will be the point person during the first
week of the upgrade should there be any problems. You may contact her or
Director Patrick Brandt of DelComm with any problems or concerns.
During the week of March 25th, Motorola will be
visiting each of the dispatch centers to perform upgrades to the MCC7500
consoles. This will cause approximately 45 minutes of down time at each
position. A specific schedule for change outs is being drafted and will be
shared with you when it is ready.
Tonight (12/28/18), starting at 1900, the City of Upper Arlington will be doing maintenance on the fiber optic network that connects the COIRS radio tower located at Station 72. This maintenance will take that site off line. The outage could last up to 8 hours and will degrade in-building walkie coverage in and around UA, especially south of Lane Ave.
UAPD and UAFD will remain on their normal COIRS talk-groups and will only move to COIRS LE or COIRS FD if the need arises. For any in building fire responses, it will be the discretion of the IC whether to move the response to COIRS FD.
All other COIRS towers will remain in service during this maintenance.
If you have any questions, please contact Jay Somerville.
XO Communications has notified COIRS that they will be performing network upgrades on the circuits that support our radio system on Saturday 06/16 between 00:01 and 06:00 and on Monday 06/18 between 00:01 and 06:00. There could be connectivity interruptions of up to 20 minutes 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 may 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 or Patrick Brandt.
