The HR splitters range, in the standard models (SAXXXX), as well as in the ST models (SAXXXX-ST) with switch and test, allowing an easy installation with no specific tools required. They become universal because the connections can be done directly with the cables without the need of a connector.

Both series have models for different telephone systems POTS (Plain Old Telephone Lines), RDSI and combined, as well as for different impedances for the telephone equipments.

At the models by country page you can search the HR splitter references used in each country: you must be aware that there could exist operators in some countries, which use a different HR model, not registered in the board. In that case you must just check out the technical features required by each operator, and use the suitable HR splitter.
