[Dispatch] GATRRS Maintenance

[Fire Communications Calendar]

WHAT'S HAPPENING: Thursday, January 27, 12:01AM - 04:00AM
*       We will be enabling our GATRRS core system for Dynamic System Resiliency (DSR).
*       All core systems will be configured for DSR and tested.

How does this affect users?
Thursday, January 27, 12:01AM -  04:00AM:
Users in Zone 1 will experience two site trunking events.  Some sites may experience up to a 15 minute outage during the move to the DSR core system.

  *   Thursday, January 27, 12:01AM
  *   The first site trunking event is when we move to the DSR core system.
  *   Thursday, January 27, 3:00AM
  *   The second site trunking event is when we move back to the primary core system.
Conventional backup resources may display a "RED X" for up to 30 min.   IF THIS HAPPENS TURN YOUR RADIO OFF AND THEN BACK ON AGAIN.
Why are we doing this?

  *   This work is being performed to provide the GATRRS core system resiliency.
 What's required of me?

  *   As with any/all maintenance occurring on GATRRS, Dispatch Centers should be prepared to use local backup radio resources prior to the start of any maintenance activity.
  *   In the field, subscribers should be aware of maintenance activity in the case that they encounter difficulty communicating with their Dispatcher and/or other subscribers.
  *   Subscribers in the field maybe required to power cycle the radio after the 'Site Trunking' event has occurred.

  *   Prior to this maintenance:
     *   City of Austin Wireless Communication Services personnel assigned to oversee the work will determine if there is a major reason to postpone or suspend the scheduled maintenance.
     *   Affected dispatch centers (if available) will be contacted prior to the start of this maintenance to check if there is concern or reason to suspend or postpone the activity.
     *   EXAMPLES of justification for calling off scheduled maintenance: Major inclement weather moving into the affected area, a multi-alarm fire in progress, or a major law enforcement related event in progress.
     *   The system and/or site service level as applied to affected coverage areas will be factored into determination for suspending or postponing the maintenance activity.
