telephone jack

The telephone jack conforms to BS6312 in the UK and other parts of the world such as New Zealand.

You’ll discover that the six pin telephone jack you see every day in your office or in the home only uses two of them for most applications.  Four of the connectors were utilised on 4-wire key-systems, 2 for voice and 2 for signalling and in some products all 6 with the final pair carrying low voltage power.  Nowadays most telephone systems are digital and use either TDM or VoIP as the means for switching and the control signals are interspersed with the bits for audio translation.

The telephone jack fits into a telephone socket which will be a Master or Secondary.  These are still found in homes.  The master is where BT’s (or your provider’s) responsibility ends.  From that plug you can run internal cables to secondary sockets.  These do not have the components in them concerned with handling the ringing signal and are therefore slightly less expensive.
