OARNet Maintenance

All COIRS System Users: 

OARnet has notified us they will be doing maintenance to the fiber network that support our system TOMORROW MORNING (11/28) starting at 04:00 and lasting approximately two hours. There will be connection outages during this time frame that will cause the consoles to lose connection and the system to go into site trunking. The outages could last longer than 16 minutes at a time and may occur several times. Dispatchers will need to use back up radios/walkies during these outages. Field units will receive the "SITE TRUNKING" notice on their radios, but can continue to operate on their normal talk-groups. 

If you have any questions or concerns, contact Jay Somerville.

System Repairs Complete

At 14:40 today, technicians installed the replacement switch card at the master site and it brought the system back in full service. The two bad switch cards are being sent back to Motorola for repairs then will be returned to Delaware to be stored as spare cards. 

Although we do not anticipate another site trunking event, dispatchers are encouraged to have at least one back up radio set to a COIRS talk-group so should the system return to site trunking, they will notice immediately. 

Thank you to Mike Sabitino, Patrick Brandt and the Techs from B&C Communications for working this issue quickly and professionally. 

Site Trunking Update

Update: Motorola reports to us that they have just completed the programming and testing of the new equipment and are sending it out on a 1pm flight from Chicago. Once it arrives, it will be installed and the system brought back up to full service. B&C Techs will notify us when work is complete and we will send an update.

We are also working with Motorola to identify and obtain a complete back up unit to keep on site in Delaware. Since this particular switch is no longer manufactured (it is not a Motorola product), we want a full back up unit on site if at all possible.

Thanks again for your patience.
