PABX Master Adaptor (RJ45)
The RJ45 line adaptors enable the conversion of data to voice signals. They are wired to the 258A/T568B specification. The adaptors convert an RJ45 socket into a BT socket to allow for the inclusion of telephones within a network.
The PABX adaptor contains a resistor and a capacitor (the capacitor is across contacts 4 & 5).
