A communication system (eg. category 5 system) comprises: an outlet unit 26 having four outlets/wire terminations A',B',C',D' to provide couplings to telephone handsets 22-25 etc; a house cable 27 containing four twisted pairs of conductors for providing discrete communication between the outlet unit and a patch termination cabinet unit 28; and an interface patch termination 31 providing entry to a two wire telephone system. A method of modifying the system is provided which utilises first and second patch units/connectors P1 ,P2, each comprising a length of cable 30 containing at least four twisted pairs of conductors, one end of each cable having a termination in the form of four subsidiary outlets A-D, each outlet providing a compatible coupling for an individual telephone hand set or comparable device, the other end of the cable having a termination in the form of a plug 35 compatible with either the outlet unit or the patch termination, respectively, to provide the system with an increased number of user channels without the need to install further cabling.
