Hi Li, Thank you very much for your suggestion. Yes, my system can receive correctly - but the transmitter does not work even I have masked APCO interrupt. The line rate is 2.3Mbs, so the PCR should be 2.3Mbs/(53*8) ->5424 cells. I have tried to increase the PCR but no luck. Do I need to check anything else ?
