Custom phone line splitter with filters for DSL that takes a single phone line RJ11 input and splits it off to two POTS phone lines with DSL noise filters and the same two lines without filters that go to two DSL modems. The original combined 2-line filter came from an old wall-mount style telephone jack that came with a DSL modem along with the little pigtail filters. This box replaces what was two worn out surface mount wall jacks that were then Y-split for phone and DSL and also had the pigtails. It was a mess of wires and occasionally the connection would drop at one of the RJ11 interfaces and required lots of wiggling until the modem lit back up.
