Noise over GXW4104


Hello everyone! and thanks for all your help and time in advance.

Recently, I got a GXW4104 and it is working ok but the only problem I have with it is the noise it delivers when a call is in progress, I have checked the ISP lines (all of them analog copper lines) and there is no noise while using them directly but the GXW4104 produces a noise similar as when there’s magnetic interference while dialing and bubble noises in call.

I have tried to execute the line analysis tests but it always returns me an empty table and downloads a file named “command_send_2020” which I don’t know for what is for.

Any help is appreciated.


Noise is from PSTN line, try lowering dB on PSTN.
