Tms Hardware Initialization Errors - Avaya Media Processing Server 500 Hardware Installation And Maintenance

Because the TMS relies on clocks, a system is functional as long as a clock is available. Failure of
the clock generates a major alarm. There is more than one span configured as a reference source in
the tms.cfg file for redundancy.
Loss of reference clocking on the TMS causes the TMS to enter a free run on the PLL. In free run,
the TMS is no longer in sync with the external network and generates frame sync errors between
the TMS DCC and the network. The result is noisy or no audio on a channel.
Recovering from Clocking Failure
The TMS software is designed to recover or resynchronize itself when a loss of clock occurs. The
system enters a major alarm state after a restart if there are no clock sources. The system
automatically recovers from the alarm condition after TMS spans go into service. Do not start any
applications while the system is in the major alarm state for the PLL. The system can be in this
alarm state for several minutes before recovering.
If a minor or major alarm condition persists for more than a few minutes you must resolve the
problem using the TMS PLL diagnostics.
The following modules can cause clocking failure:
• TMS PLL
• TMS DCC
• NCD
• PLI
The TMS PLL can generate alarms due to the following conditions:
• Incorrect PLL configuration in tms.cfg file
• Span problems such as the span in the sync list is not in service
Troubleshooting Clocking Failure
1. Verify that the system clock configuration in the tms.cfg file is correct for your installation.
2. Verify that the spans selected in the sync list are in service. The alarm log contains a history
of faults.
3. Use NCD to isolate the source of the fault. Use the commands from the tms-common
component of a vsh (see NCD PLL diagnostics).

TMS Hardware Initialization Errors

A TMS hardware initialization error indicates that one or more of the hardware components on the
TMS are generating an error after the TMS is reset. Hardware initialization errors include a number
of components on the base TMS card as well as any of the daughter cards attached to the base
TMS card.
Any hardware error detected affects the usability of the TMS card. Most hardware initialization errors
prevent the TMS from loading its runtime image or configure resources required by the application.
