HELLO & WELCOME

Just spent quite a while running a cable from a PAP2T in the basement, up through the ground floor to the 1st floor (in British English) so...

1st Floor - Analog telephone

Ground floor

Basement - PAP2T


at first things seemed to work OK but the audio was faint. But now I'm having problems whereby the DTMF tones aren't being 'heard' correctly by the PAP2T and are being misinterpreted as other digits. Another big problem is that audio from the microphone on the analogue telephone is no longer being transmitted.

I'm wondering if the cable is maybe snagged/pinched or if something has gone wrong somewhere else because it's totally unworkable as things stand. Could it just be that the cable length is too long for the PAP2T and I've got cable attenuation problems or?

I tried plugging the SAME analogue phone into the PAP2T's other port and everything works as normal. Microphone works as it should and DTMF digits are correctly sent/interpreted. So I guess it's either:-

That particular port on the PAP2T
The cable being too long
The cable being snagged somewhere
Something else I've not considered?

Any insights most welcome. Tearing my hair out!

It's possible. How long is the cable run?

If you're in the UK then take a look at the following topic "UK REGIONAL SETTINGS FOR CISCO, LINKSYS & SIPURA DEVICES." and configure the PAP2T accordingly.

PAP2T definitely configured correctly, the other port has another extension strung off it and that one works fine. I don't know how long the cable run is, but maybe 25 metres?

[WelshPaul]

I don't think 25 feet is an excessive amount and most ATA's should handle that run just fine in my opinion. Where did you get the PAP2T from? The reason I ask is that the PAP2T was discontinued years back and the ones for sale on eBay are usually cheap Chinese knock-offs and maybe thats why its struggling (I did say maybe)...

Did you have to wire up the extension cable yourself? How is it connected to the PAP2T? Are you using one of these? Or is the extension cable plugged directly into the PAP2T via its own RJ11 plug? Whats on the other end of the extension cable?

[WelshPaul]

Ohh hang on, I miss-read... 25 METERS is roughly 80 Feet! That is likely going to be the cause. Does the phone ring ok when receiving a call?

There was this post previously that is similar to yours:
iantor @ phone ringing unreliable with SPA112

If your phone is ringing ok when receiving a call then we can try messing around with the gain settings on the PAP2T...
