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 ?

Maybe your PCR is too small?
or you can try receice first
