You will need
- - rubber gloves;
- - duct tape.
Remove the tube on parallel phone, which despite a broken cable left connected to the network. This will prevent the strike voltage ringing that may appear on the line in case of receiving an incoming call. If you only have one camera, or breakage happened in a place that was disconnected all the phones in the apartment, have to work in rubber gloves.
Find the location of cable damage. If you visually can not find it, use contactless inductive fault finder. This device can borrow the telephone operator. If this is not possible, the cable cut, the break is unknown, it is easier and faster to replace the whole thing.
For splicing the two-wire flat cable the old design with each of the parties will razdvoenie "noodles" along the cutters so that the cut line was exactly in the middle. Tips to gently clean. Remember that insulation "noodles" is not made of PVC, and polyethylene, so when you sweep accurately calculate the effort to remove only the insulation without damaging the conductor.
One of the wires of one end of the cable connect with any of the wires other end. The polarity is correct when it is unnecessary. Then do the same and mix with the remaining wires. Carefully insulate the joints from each other. Then verify that the numbers, which after breakage stopped working again.
Telephone cables of the new design have an outer shell, within which are laid in a row two or four stranded conductor, each of which has its own colored insulation. The outer shell is easily removed with almost no risk of damage to insulation of conductors.
If the cable is two-wire and the procedure for splicing is same as for the "noodles". Four-wire cable, which is more common, repair the following: last wire in the series will not connect or even not clean because they are not involved, and the wires in the middle, crystite in the manner described above.
If the line is connected to a special telephone designed to work simultaneously with two lines (they are found, though rarely, in the offices of the leads may also be involved. Splice into this line, simply connecting the conductors of the same color.
After work and making sure that all the phones are reconnected to the line, place the handset on the device from which you removed before working.
