The OKWIN system has begun the process of migrating from a “proprietary” Analog system to a “non-proprietary” P25 compliant Digital system. The first step in this migration includes replacing the existing analog zone controller with a new P25 compliant digital zone controller. The migration is scheduled to begin on the morning of Tuesday, April 5th and should take ten (10) days to complete.  

During normal operation, dispatch centers are typically able to communicate with first responders operating within the coverage area of the OKWIN system independent of their respective tower sites. This capability is referred to as “Wide Area Trunking.” Unfortunately, system capabilities will be reduced at different periods of time during this cutover. This reduction will negatively impact the “Wide Area Trunking” capabilities of all radio system users. Dispatch centers and first responders that rely on multiple tower sites for their operation (i.e. County Sheriffs, EMS Entities and OHP) need to develop and implement an operational plan specific to this cutover.

Additional information will be added to this page in the near future. In the meantime, please be aware of the following items:

• Two (2) separate conference calls have been scheduled to answer your concerns related to the migration to the new P25 digital zone controller.
  • Conference Call #1: (COMPLETED)
    • Tuesday, Mar 8th @ 3:00 PM
    • Bridge (877) 825-8522  Passcode 1040260

• All dispatch centers should confirm their backup dispatch equipment is operational due to the short term loss of console functionality.
• All first responders in your dispatch region should be notified of your region specific operational plan during the loss of “Wide Area Trunking”.
• Site Trunking will be available during the period of time that “Wide Area Trunking” is not available.
• “Telephone Interconnect” functionality will not be available after this upgrade is complete.
