Home telephones rely on a wired connection to a phone jack. The phone cord that connects the base to the jack uses a plastic RJ-11 connector on each end. The RJ-11 connector is similar in shape, but a little smaller than the RJ-45 connector used on the end of CAT5 computer cables. If the phone cord or an RJ-11 connector becomes damaged, a new connector can be installed with a specialised RJ-11 crimping tool.

Cut off the damaged end of the phone cord with a pair of wire cutters.
Place the newly cut end of the phone cord into a telephone cord stripping tool. Squeeze the handles of the stripper to remove the outer sheath surrounding the coloured wires inside the cord.
Hold the newly stripped phone cord so that the green wire is on your right. Slide a new RJ-11 connector (with the locking clip facing upwards) onto the end of the cord.
Insert the end of the connector (with the wire inserted) into a telephone connector crimping tool. Squeeze the handles of the crimping tool tightly to compress the connector onto the end of the cord. Remove the RJ-11 connector from the crimping tool.
Connect one end of the phone cord to the base of the phone, and the other end to the phone jack. Lift the receiver and listen for a dial tone.
