I seem to have developed a strange problem with my phone/internet system. It started when I received a call lunchtime from 000000000000 which my CPR Callblocker duly blocked. When I tried to use the phone this afternoon I discovered my line was dead so I plugged a simple handset straight into the socket and my line was normal. Next, I removed the callblocker from the system and I was able to make calls with my usual phone equipment. But the internet immediately tripped out and went through a re-boot. Now, each time the phone is used the same thing happens. I'm treating the fake phone call as a red herring but I'm just giving you the full picture. If anyone has any ideas..... :dunno:
I think I've solved it. :laugh: I seem to have the wrong cable connecting the phone to the filter which might explain everything. But it's too dark to fiddle around right now so it can wait until morning.
::)
Normality is restored! I'd connected the phone to the broadband socket on the filter. ;D
:slap:
I'm just shocked the phone worked at all through the broadband. :o
I'm shocked it fitted in the socket. ;)
That's where the callblocker came in Ben. I used the callblocker cable to connect the phone to the BB filter. :whistle: But now I think I might be able to fix the callblocker too. There is just no stopping me now! ;D
RJ11 sockets are usually wired with the centre pair being the active line.
A DSL filter only filters the phone socket. The "DSL" socket is a straight connection to the phone line.
That explains why the phone worked in that socket. But is that why the internet connection was nuked when I used the phone?
QuoteBut is that why the internet connection was nuked when I used the phone?
The internet was affected because the phone wasn't filtered.
I knew if I waited long enough someone would come up with a sensible answer. :thumb:
A more detailed explanation...
QuoteWhat a Microfilter does
A microfilter performs two main tasks. First, it prevents high frequency noise from appearing at the telephone and potentially decreasing voice quality. Second, it prevents the telephone equipment from interfering with the modem by preventing harmonics, overtones and changes in impedance caused by the telephone equipment.
Thanks for that information. :) I know the filters can wear out over time and need replacing.
