Last night close to midnight my ADSL crapped out, would sync & then drop sync in a endless cycle. I though seeing it's about midnight they must be doing maintenance of sorts so left it for the morning.

This morning I I checked the SNR & Attenuation on my router and the SNR was floating between -1 & 4 dB which is not good. I unplugged the phone & pots filter and my SNR shot up to the 30's and I could sync again so I plugged in a spare filter & reconnected the phone so everything is a-ok again.

Does Telkom replace these POTS filters when they break or do I have to buy a new one?
This thing went from working to not working and we had no lightning in a very long time.
 
Na, you would have to buy a new one if you needed it(You have a spare) they cost about R50?
 
Try without it. Iirc the POTS filter only filters the signal going to the telephone, making sure that it doesn't collect digital noise from the ADSL router. Moderns routers have fairly clean signals, and your phone should operate fine without the filter.
 
I highly doubt that Telkom would replace a damaged unit, unless it was DoA (dead on arrival).\
They cost less than R50 usually, so they're cheap to replace.

The splitter filter thing that you get from Telkom is just a normal 2 way splitter, with a filter for the telephone port, so the ADSL modem port is unfiltered. So if you don't have a telephone, then you won't need a filter to start with.
I'm using my ADSL modem without a splitter filter, and I have a telephone that is connected via a filter and my ADSL doesn't drop when I make/receive phone calls.

If it's one of the old Telkom POTS filters just undo the screw under the ICASA sticker and open the unit. If you have a soldering iron just remove the solder on one leg of VR1 or carefully snip one of the wires and see if that doesn't solve the problem. VR1 which is connected directly across the red and green telephone wires seems to be some type of lightning protection component such as a gas arrestor/MOV/Zener etc. If the filter is still misbehaving you could replace the four brown capacitors and two resistors.

Just confirmed that as well. Techies don't even keep spares in their bakkies anymore (officially).
