This splitter is primarily intended for use with older 4-line analog phone systems, which use 8P8C (RJ45) cables. This will split the lines, allowing two such phones to be connected to the same input line.
Note that this will NOT work with Ethernet/LAN cables. If you wish to connect two or more Ethernet lines to the same source, please check out our line of Network Switches.
