Network Maintenance – April 11th
OARNet has notified COIRS that they will be performing critical network maintenance on the circuits that support our radio system on Wednesday 04/11 between 00:01 and 04:00. 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 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

LEERN End of Life
With all Central Ohio law enforcement agencies now on 800mhz and a common radio template coordinated so everyone has access to operational talk-groups, the patch to the state’s Law Enforcement Emergency Radio Network or LEERN is being discontinued. Officers and agencies are encouraged to do directly to the dispatch or TAC channel to contact an agency. When requesting the Chopper from CPD, they will come directly to your agency talk-group for communication. LEERN will be removed from the template during the next reprogramming.
We also have LAW MUTUAL , located in zones 6 and 9, used/monitored by all agencies in Delaware County, NRECC agencies and Worthington PD. The equivalent in Franklin County would be SO-25 which can be found in zone 28. Most importantly, your dispatcher can set you up on one of the many regional TAC talk-groups that are available for inter-agency use.
This will be effective at 0600 on November 1st.
