Maintenance Alert: Upper Arlington

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.
