Ivory Modular Triplex 3 Line Adapter

The TRANS USA PRODUCTS 20-524 is an ivory-coloured modular adapter that splits a single wall jack into three separate line connections. It is designed for offices or homes needing to add two single-line devices to an existing two-line telephone hook-up. The unit uses a standard phone jack plug for direct connection to the wall outlet.

Practical limits of modular telephone wiring

The adapter provides a 4-4-4 wiring configuration across six wires to support the triplex arrangement. It functions within the constraints of standard modular telephone cabling and does not amplify signals or add line capacity beyond the existing service. Performance depends on the quality of the premises wiring and the telephone service provider's line conditions.
