Fixing up Phone Troubles
The only tools you need to troubleshoot your home telephones are a screwdriver and an inexpensive telephone with a modular line cord. That's right - the best piece of electronic test gear for chasing down a dead-phone gremlin is a spare $10 discount-store phone. That's essentially what the phone company repairman uses. First, however, you need a few telephone wiring basics. The telephone plugs into a modular wall jack, either along a baseboard or in a wall coverplate. The line cord has a universal modular jack (plug) at both ends, so that it is replaceable.
Most modern phones are one-piece (the Princess-style phone), but some have separate dial units and handsets connected by a similarly replaceable handset cord. The modular wall jack contains four color-coded terminals, to which are connected the corresponding-color wires from the incoming plastic-sheathed cable and the short wires to the jack. Telephone cables carrying one and two lines use the color code: Red wire -Line 1 Green wire Yellow wire -Line 2 Black wire In some new homes, the telephone cable contains more wires in order to handle more lines.
The color code for a four-line cable is: Blue with white stripe -Line 1 White with blue stripe Orange with white stripe -Line 2 White with orange stripe Green with white stripe -Line 3 White with green stripe Brown with white stripe -Line 4 White with brown stripe Round, plastic-sheathed telephone cables run to locations throughout the house from a single point: the network interface. The network interface is where the telephone company's wires (their responsibility) meet the customer's wires (the customer's responsibility). If the problem occurs before the interface, the phone company fixes it for free. If the problem occurs after the interface, you fix it or pay the phone company to come into your home and fix it.
Corded Phones If there is more than one phone on the same telephone number, unplug every phone. Then plug in each phone, one at a time, checking for a dial tone with each. If just one of the several phones causes the line to go dead, that phone needs to be replaced. If none of the phones gives you a dial tone, jump to step
If you have just one phone on the line:
1. Unplug the line cord from both phone and wall jack, then plug it in again.
2. Repeat with the handset cord if the phone has one.
3. Replace the line cord with the spare line cord.
4. Replace the handset cord with the spare line cord.
5. Replace the dead phone with the spare phone. If you don't get a dial tone with the spare phone, the trouble is in the line, not the phone.
6. Find your network interface module (either inside or outside the house near the telephone line's entry point to the building), open the cover and plug your spare phone directly into the test jack for the line.
(If there is more than one line, test each one.) If the telephone works, the trouble is in the wiring between the network interface module and the telephone jack. Using a screwdriver, remove the covers of both the interface module and the telephone jack, disconnect the red and green wires and substitute the yellow and black wires - yellow for red, black for green - at both ends. 7. If the telephone does not work even when plugged into the network interface, the trouble is in the telephone company's wires. Cordless Phones To determine if the problem is in the cordless phone or in the line, replace the cordless unit with the spare corded phone and run the tests above. If the problem turns out to be the cordless phone: 1. Make sure the unit's batteries are charged. If they are more than two years old, they may need replacing. 2. Make sure the unit's power module is plugged into the wall and the back of the unit. 3. Check the electrical outlet with a radio or lamp. 4. Make sure the unit's sending antenna is in the upright position and that you are within 50 feet of it. If the unit seems truly dead, it has probably been zapped by a lightning surge and is dead. Go to the store.
