Telephone Circuits Telephone In-Use Indicator When a new computer modem enters the household, the demands on the home phone line skyrockets. The Internet surfer can use phone time on a par with the most talkative teenager. And the computer modem user can be quite sensitive about his privacy: The phone wiring may be modified so that the modem is always in control by connecting the phone line directly to the modem and connecting the rest of the phones to the modem’s “phone” jack.
But this solution gives the computer user too much power over the phone line and it doesn’t solve the problem if two computers share a single line. Here is a simple blinking LED circuit which will alert users when the line is in use before the receiver is lifted.

These devices work on the Voltage Drop principal! The Privacy Devices are placed in front of each phone or modem, and know that the line is busy off-hook if the voltage drops below a threshold of 24VDC. If the talk battery is below 24V, the device won’t conduct electricity so the phone won’t be able to pick up the line. You can’t use these on very long cable runs because the voltage doesn’t drop much on the other run when you go off hook.
If the voltage doesn’t drop below the threshold of the Privacy Device, the Privacy Device won’t exclude. Keep these facts in mind when using these: They must be put in front of each device that you want to be excluded from the line when it is busy you can’t just put it in front of the phone you don’t want interrupted.
You can’t put two of these in-series! Some Credit Card Terminals and other devices already have these built-in, so if you can’t use a Privacy Device on these terminals can’t put two in-series. The telephones or other devices have to be within a couple of hundred feet of one another.

My advice here is aimed towards connecting both your existing line Line 1 and your new second line Line 2 on new or existing jacks at the locations of your existing jacks. This will provide you the most flexibility in determining how to use your expanded phone service. This advice is only applicable if your phone cable is normal station cable with two or more pairs of wire.
Most people will be able to add a second line to their existing jacks without installing any additional cable. Two wires one “pair” are needed for most phone line connections. Normal station cable what your phone tech may call “JK” used for residential installations has four wires two “pair”. Single line installations only use one pair, leaving the second pair available for the second line. You may find that your home was originally wired with both pairs connected to the jacks and is essentially “two-line ready”.
If you plan to “do it yourself”, I recommend you consider accomplishing all of your rewiring before actually ordering your second line from the phone company.

Busy Signal As a rule, these days if a person is currently engaged on their telephone, any incoming calls will be automatically bounced to some sort of voicemail system. There are not only consumers today who have become so unaccustomed to being thwarted by the stentorian tones of a busy signal that they are temporarily flummoxed at the concept of having to hang up and dial again later, there are also younger users who have never heard a busy signal.

The red and green wires are on the two center terminals of a normal phone jack, and the black and yellow wires are on the two outer terminals.

Many if not most line cords that you receive when you purchase a phone to go between the wall jack and the phone only have the two center wires.
To save money, the outer two are omitted. When you bring a second phone line into the house, this new line uses the yellow and black wires. If you have a two-line phone , then the phone is normally ready to accept the second line automatically on the yellow and black wires. You plug one line cord into the phone and it splits the two lines inside the phone. Make sure that the line cord between the jack and the phone actually contains all four wires!
