A nalog telephone lines carry voice and data signals much like electrical wire conducts current. Both must be spliced or repaired from time to time and in much the same manner. However, specific splice connectors and tools are used for each type application. A telephone splice connector is typically filled with a gel substance to make the connection more watertight when it's used to splice or repair a phone line.

1 Unplug the Telephone Splice Connector to be serviced and cut off the damaged or uneven end.

2 Trim back the outer jacket of the phone cable approximately two inches by lightly cutting the jacket using the telephone splice connector tool. Be careful not to cut into the insulation of the individual colored phone wires within the cable.

3 Strip off approximately 1/8-inch of insulation from the ends of each colored phone wire to be spliced.

4 Trim and prepare the end of the additional telephone wire to be spliced into the existing phone wire. Trim the outer jacket back approximately two inches using the telephone splice connector tool to expose the colored phone wire conductors inside. Trim back 1/8-inch of the insulation on each wire to be spliced.

5 Lay a colored wire into one of the telephone splice connectors and hold in place. Position the same colored wire from the second telephone wire into the opposite end and lay into the splice connector.

6 Fold the telephone splice connector closed by hand and squeeze it shut using the telephone splice connector tool. This will crimp the wire permanently shut and seal the connection.
