A range of three line-adapters allowing telephone equipment to be connected to RJ45 structured wiring systems. All units comply with OFTEL approval NS/G/23/L/1090005 & BS6312. These have a male RJ45 connector and female UK telecom 431A socket.

Secondary Converts BT style plugs to structured wiring RJ45 plugs whilst also adjusting the signal impedance to conform to OFTEL standards.
PABX/PSTN master Performs the same functions as the Secondary adapter, whilst also featuring a bell capacitor to ring the bell on the telephone, plus an 'out of service' resistor. This unit is for use both on a PABX telephone system and on a direct incoming line (note: In the UK. Openreach no longer recommend use of surge arrestors as they can interfere with broadband circuits).
PSTN master Performs all the above functions, whilst also features surge protection to disperse any electrical spikes. This unit may be used on a direct or incoming line.
