Site Controller Failure Impact on GTR 8000 Base Radio for
Trunked Operation
If the link fails between the base radio and the site controller, the base radio dekeys and does not
handle any MSU traffic. MSUs attempt to operate on another channel at the site. If another channel is
not available, the MSUs attempt to register at another site.
For HPD and repeater site operation, the base radio receives external frequency reference and
network time synchronization from the active site controller over the Ethernet link. If there is a loss of
the external time and frequency reference source, the base radio continues to maintain its own time
and frequency stability to continue operations for a specified amount of time without degradation.
Afterwards, operation continues with minimal degradation.
8.4
Conventional Site Controller Failure - Impact on GTR 8000 Base
Radio for Conventional Operation
For IP interfaced conventional base radios, a conventional site controller provides support for dispatch
consoles to manage and control the conventional base radios in K core and M core type systems, the
conventional site controller only provides support for the console to manage and control the
conventional base radios when the primary (and optional secondary) zone controllers are not
reachable.
If the conventional site controller fails when it is the active call controller in either type system, the
dispatch console loses its ability to manage and control the channel resources. However, subscriber
radios may still be able to maintain communications using repeat functionality of the base radios or
when the base radios are connected to a comparator. The comparators repeat functionality enables
wide area repeat for subscribers.

Motorola Solutions Support Center

Motorola Solutions Support Center (SSC) can help technicians and engineers resolve system
problems, and ensure that warranty requirements are met. Check your contract for specific warranty
information.
Motorola Solutions assigns a tracking ticket number that identifies each support call. This ticket number
allows Motorola Solutions to track problems, resolutions, and activities for the call, and if possible,
communicate the resolution and a status of call so that the SSC can note the resolution and close the
ticket.
8.5.1
Information Necessary to Contact Motorola Solutions Support
Center
Before calling the Motorola Solutions Support Center (SSC), log all steps taken to troubleshoot the
problem and any results of those steps. The SSC can use this information to determine the appropriate
support actions.
Listed is the following information to collect before calling the SSC:
• System ID number (such as 2CB5). Each zone in the system has a unique system ID number
• Location of the system
