I have an AG2000 loop start interface, when I record to a WAV file using the RECORD step, I get a sound spike every 200ms. I've adjusted the number of buffers, and checked the config file. Has anybody else has a similar problem. <br> <br>The spike confuses speech recognition on a variable basis. <br> <br>The info below is my oamsys cfg file for the board <br> <br>#-------------------------------------------------------------- <br># Originally created from input file gbr\a2lps.cfg. <br># Detailed board settings for: <br># Product = AG_2000 <br>#-------------------------------------------------------------- <br> <br> <br> <br># Uncomment the appropriate Trunk Control Protocol(s) <br> <br>TCPFiles[0] = nocc.tcp # "no trunk control" protocol <br>TCPFiles[1] = lps0.tcp # Loopstart protocol <br> <br> <br># DSP (.m54) files to link in <br> <br>XLaw = mu-LAW <br> <br> <br>DLMFiles[0] = gtp.leo <br>DLMFiles[1] = voice.leo <br>DLMFiles[2] = svc.leo <br> <br>NetworkInterface.Analog[0..7].ConfigFile = a2eurlsc.slc <br> <br>Clocking.HBus.ClockSource = OSC <br>Clocking.HBus.ClockMode = STANDALONE <br> <br>DSP.C5x.[0..3].Files[0] = adsir.M54 <br>DSP.C5x.[0..3].Files[1] = callp.M54 <br>DSP.C5x.[0..3].Files[2] = dtmfe.M54 <br>DSP.C5x.[0..3].Files[3] = echo_v3.M54 <br>DSP.C5x.[0..3].Files[4] = mf.M54 <br>DSP.C5x.[0..3].Files[5] = ptf.M54 <br>DSP.C5x.[0..3].Files[6] = rvoice_vad.M54 <br>DSP.C5x.[0..3].Files[7] = signal.M54 <br>DSP.C5x.[0..3].Files[8] = tone.M54 <br>DSP.C5x.[0..3].Files[9] = voice.M54 <br>DSP.C5x.[0..3].Files[10] = wave.M54 <br> <br>DynamicRecordBuffers = 10 <br>Buffers[1].Size = 1600 <br>BUffers[1].Num = 96 |

Further information, due to a customer request, I had to revert the machine running the above application to NA2002-1 (so that I could change a Show N Tell application). In the persuit of danger, I tried the above app. and it works with no problem. The only change I had to make to the oamsys files was to drop the DynamicRecordBuffers entry. |

Sorry forgot to say original config was NA2003-1. |

Just following up. Did going back to NMS 2002 fix the problem? |

Sure did. But I still get Teleflow 2004 aborting with a Memory protection error. |

Likely, the cause of the memory protection errors is TeleFlow build 1031. Recommend you download again. The new build, #1121, fixes certain stability issues. <br> <br>On the sound spike issue, it seems like there is a bug with NA2003-1 and the Euro version of the AG2000 card (I assume that is what you have). We have not had any such problems with NA2003-1 and AG2000 in North America. I'd love to learn more, if anyone else has encountered this problem. |
