Is there any way to find which signals are coming from PSTN(Telco)side? I have a FXO disconnection problem and almost tried every thing. Please help.

Regards,

MAR

Record your tone on the PC, attach it here together with config and mentioen the applicable country.

I've tried but no luck. Is there any way to find out which type of signals PSTN are sending.

It's probably 425 Hz after all. The recording you sent has a lot of noise and the frequency analysis can be impacted. The main problem is that tone-based is unreliable in itself.

Cisco IOS Software, 2800 Software (C2800NM-ADVENTERPRISEK9-M), Version 12.4(3h), RELEASE SOFTWARE (fc2)

c2800nm-adventerprisek9-mz.124-3h.bin

That "might" be CSCek27376. Do you use "connection plar XXX" or "connection plar opx XXX", and can you switch to the second if using the first ?

I've checked but no output. So anyway thanks. You did'nt tell me how to check the PSTN signals?
