The primary purpose of the telephone is to transmit and receive voice signals allowing two people with telephones to communicate with each other. To be of practical value, the telephone must be connected to a switching. Each subscriber telephone is connected to the telephone company's Central Office (CO) by two wires referred to as the "Local Loop." A simplified diagram of this connection is shown in the Block Diagram. The TIP and RING designation of the "+" and "--" leads come from the days of the manual switchboard. The tip of the plug the operator use to connect telephones carried the "+" lead and the ring immediately behind the tip carried the "--" lead. The central office provides 48 Volts DC to operate telephones. When a telephone is on the hook, no current flows, and approximately 48 VDC can be measured at the Tip and Ring terminals on the telephone. A capacitor in series with the ringer prevents DC current flow through the ringer. When the handset is picked up, the hook switch connects the voice circuit to the line, and DC current flows from the CO battery, through the wires and the telephone. Due to the resistance in the wires and CO equipment, the voltage at the telephone will drop to about 6 to 12 Volts. The current flow is detected by a current sensor in the CO, and the switching and control system (from here on we'll just call it "the system") responds by sending a dial tone to the telephone. The system then waits for dialing to begin. When dialing is complete, the CO checks to see if the dialed telephone is busy; if the dialed telephone is on hook (the current sensor on the dialed telephone line provides this information), then a 90 Volt AC ringing signal is sent to the dialed telephone and the ringer will ring, signaling that someone is calling. When the handset is picked up, DC current will be drawn from the CO battery, signaling the system that the called party has answered. The system stops providing 90 VAC ringing voltage and connects the two phone lines together, letting the parties talk. As you can imagine, the system is not simple. Along with the tasks mentioned above, it must generate busy signals, keep track of the length of calls for billing purposes, route calls to other COs, and connect voice recordings to advise you of problems in completing calls. The ringer circuit is connected directly across the Tip and Ring inputs. The capacitor blocks the 48 VDC that is present on the inputs when the phone is on the hook. To signal an incoming call, the Central Office places a 90 VAC 20Hz signal on top of the 48 VDC. A special circuit oscillates the frequency at about 3kHz. The buzzing sound is thus produced by the buzzer changing dimensions at 3kHz. During the positive portion of the 20Hz ringing signal, the three neon bulbs give a visual indication of the incoming call. When the hook switch is not depressed the telephone is ready to transmit and receive. The rectifier protects the integrated circuit (IC) and other components that may be damaged by a reversal of polarity transmission begins when you speak into the microphone. The main elements of the dialer are the keyboard and the dialer IC. PARTS LIST & IDENTIFICATION Contact Elenco Electronics if any parts are missing or damaged.

If your kit has a red wire on the input jack going from point T1 (on Ringer PCB) and green/black wire going from point T2, make the test cable as shown. See Step 8 on the other side for Wiring/Tubing Assembly instructions. - OR - b. If your kit has a red wire on the input jack going from point T2 (on Ringer PCB) and a green/black wire going from point T1, reverse the wire connections on the test jack. See Step 8 on the other side for Wiring/Tubing Assembly instructions. Plug the telephone line into the input jack of the PC board and the test cable jack as shown. Next, plug the 9V battery into the battery snap. No tone should be heard. Connect the 10kΩresistor to the leads of R2 and D1 (see figure). You should hear a tone from the buzzer when the resistor is connected the two leads. Now remove the resistor and the tone will stop. Ringer test fails, then: a. Check that the battery is connected with the right polarity to the test cable. b. Check your 10kΩresistor. c. Check wires from buzzer and jack to PC board. Be sure that none of these wires have broken off. d. Check the telephone line for a good connection. Remove the test cable from the ringer PC board. Return to Step 3 of the Assembly Instructions.
