Abstract:
A method of controlling a multi-channel processor board in a telecommunications system, the method comprising:monitoring, by a controller on-board the multi-channel processor board, the fault status of a multiplicity of processor cores, each arranged to process one or more speech channels, distributed amongst a plurality of Digital Signal Processors (DSPS) of the processor board, said monitoring step including receiving fault alarms from fault containing DSPs said fault alarms identifying faulty core(s) and/or associated speech channels; sending an alarm notification from the on-board controller to an off-board controller, said alarm notification identifying the faulty core(s) and/or associated speech channels; returning a reset command from the off-board controller to the on-board controller; identifying by the on-board controller, which of the processor cores are faulty; and issuing by the on-board controller, either corresponding individual core reset commands, or DSP reset commands to reset the DSPs to which the faulty cores belong.
