| 摘要 |
A method of controlling a multi-channel processor board (1a) in a telecommunications system comprises monitoring the fault status of a multiplicity of processor cores (3), each arranged to process one or more speech channels, distributed amongst a plurality of Digital Signal Processor s (DSPs) (2a-2d) of the processor board (1a). Monitoring comprises receiving fault alarms from fault containing DSPs at an on-board controller (5), and notifying an off-board controller (8) of a received fault alarm including identifying the faulty core(s) and/or associated speech channels. The off- board controller (8) returns to the on-board controller (5) a reset command, whereupon the on-board controller (5) identifies which of the processor core s (3) are faulty and either issues corresponding individual core reset command s or issues DSP reset commands to reset the DSPs (1a-1d) to which the faulty cores (3) belong.
