SECONDARY 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 Secondary adaptor is effectively a passive unit for a second phone sharing a PABX extension or for digital PABX.
