Corning Cable Systems Universal ADSL/VDSL Indoor POTS Splitter splits ADSL signals from voice signals on the same subscriber line inside the premises. The universal indoor POTS splitter is fully compliant to VDSL and backward compatible with ADSL. This small, robust splitter can be mounted in any interior location - wall, desk or over an existing wall outlet. This splitter is equipped for possible tool-less, spring-clip terminal block, or phone jack inputs.
If you want a DSL splitter but don't need a weatherproof version, this one is much easier to install. If you're connecting bare wires, just shove them in the spring terminal jacks. If you have module plugs, use the modular jacks instead. Or mix and match. For instance, if your DSL modem was nearby, just plug it's modular cord into the DSL MODEM jack and use the spring terminals for the phone line in and out.
