**SYSTEM MAINTENANCE**

Tonight (03/17) between 23:00 and 05:00, XO Communications will be doing work on the T1 circuits that run between Dublin Justice and Avery Road. They report the circuits may go down for up to 5 mins at various times causing Wothington & Dublin consoles to lose connection and possibly putting the Dub/Wor side of the system into site trunking.

 

Please be sure your users are notified and back up plans are in place.

 

We did experience two short console outages last night when one of the T1 lines reset. XO will be checking that line as well as part of this maintenance. 

System Optimization Report

Motorola engineers have completed their system optimization work on the Dub/Wor simulcast zone. They specifically reviewed system coverage and performance off of the Huntley Bowl tower site. All systems were reported in excellent working condition and functioning without error.

Motorola did specifically test coverage inside Riverside Hospital ER after reports of radios going "out of range" while inside the building. It was discovered that the radios only go "out of range" on the Dub/Wor simulcast zone, but still have service on the Delaware simulcast zone. It is believed that a bi-directional amplifier inside the hospital is rebroadcasting 821 frequencies, but not 806 frequencies, or in some other way interfering with 806 frequencies. Futher investigation by radio staff will attempt to confirm this theory. To immediately resolve the issue, talk-groups WOR DISP, WOR FTAC1, WT ALERT, WT EMS1 and WTEMS2 have been set to roaming so that they will switch zones, if needed, to ensure coverage. This switch is transparent to users.

System Optimization Work

On Monday March 8th, Motorola engineers will be conducting system testing and optimization on the Dub/Wor simulcast system. Users shouldn't notice this work unless a problem is discovered.

In addition to optimization, they will be checking the efficiency and coverage of the Huntley Road tower to ensure it is performing to is maximum, including the reported coverage issues when users go inside Riverside Hospital ER.

A post service report will be provided on the web site when work is complete.
