The current which powers your telephone is generated from the 48V battery in the central office. The -48V voltage was selected because it was enough to get through kilometers of thin telephone wire and still low enough to be safe (electrical safety regulations in many countries consider DC voltages lower than 50V to be safe low voltage circuits).
The line feeding voltage was selected to be negative to make the electrochemical reactions on the wet telephone wiring to be less harmful. Some older offices employ battery reversal (swap DC feed to tip and ring) to signal off-hook at the remote end. The current sent to telephone line as an another advantage besides that it supplies the operating power for your telephone. Full-Duplex is a term used to describe a communications channel which is capable of both receiving and sending information simultaneously.
Telephone sets (ordinary analog ones) have only 2 wires, which carry both speaker and microphone signals.
This function can send and receive audio signals at the same time is accomplished by designing the system so that there is a well balanced circuit in both ends of the wire which are capable or separating incoming audio from outgoing signal.
Nowadays POTS is sharply bandlimited due to the fact that the line almost always is digitally sampled at 8kHz at some point in the circuit.
The bass frequency response is limted because of the limitations in telephone system components: transfromers and capacitors can be smaller if they don't have to deal with lowest frequencies.
The telephone has a circuit called network interface (also called voice network or telephone hybrid) which connects the microphone and speaker to the telephone line. The actual amount of signal which is reflected back depends on how well the balance circuit of the hybrid matches the 2-wire line.
The signal which is reflected back is not always bad and in normal telephone some if it is really intentional by the design. When the central office want to make your telephone ring it will send an AC ringing voltage to the line which will ring the bell in your telephone.
The ringer is built so that it will no pass any DC current when it is connected to telephone line (traditionally there has been a capacitor in series with the bell coil).
For more information about telephone ringing take a look at my telephone ringing circuits web page. The most common one is called pulse dialing (also called loop disconnect or rotary dialing). Tone dialing is more modern dialing method is usually called with names Touch-tone, Dual Tone Multi-Frequency (DTMF) or Multi-Frequency (MF) in Europe.
This circuit allows you to record audio from a telephone line into a tape recorder or computer soundcard. A while ago I got an email asking for the schematic of a circuit to detect cut phone lines.

Personalize your ceiling fan in five easy steps and get a combination and pricing you like! The 48V voltage is sent to the telephone line through some resistors and indictors (typically there is 2000 to 4000 ohms in series with the 48V power source).
48V voltage is also easy to generate from normal lead acid batteries (4 x 12V car battery in series).
When the wires are at negative potential compared to the ground the metal ions go form the ground to the wire instead of the situation where positive voltage would cause metal from the wire to leave which causes quick corrosion. PBXes may use as low as 24 Volts and can possibly use positive feeding voltage instead of the negative one used in normal telephone network. The signal path between two telephones, involving a call other than a local one, requires amplification using a 4-wire circuit. This function is done by telephone hybrid circuit contained in the network interface of the telephone. The absolute, theoretical limit (with perfect filters) is therefore 4kHz - but this isn't reality, 3.4 kHz maximum frequency is. Other reason to drop out the lowest frequencies is to keep the possibly strong mains frequency (50 or 60 Hz and it's harmonics) hummign away from the audio signal you will hear. Network interface circuitry is designed so that it sends only the current changes the other telephone causes to the speaker. In the vast majority of cases, the match is quite poor, resulting in a considerable level of signal being reflected back. The separation of the received and transmitted audio could be done much better with modern electronics than with old phones, but but people who use the telephone prefer to hear some of their own voice back.
Most of the parts for this circuit can be scrounged from an old modem, with some work, it is possible to rewire the modem circuitry and use the old modem case. When my husband and I first moved into our house, we were on a tight budget, and a fancy ceiling fan was not in the plan. What does a designer do when a client insists on ceiling fans in all the major rooms of the house?
Collected below are the Contractor Indoor fans from the Contractors Design ceiling fan collection by Ceiling Fan Resource about Fan designs, Ceiling Fan operation, Reviews on Ceiling Fans and solutions to Ceiling Fan problems. The premier choice of designers and architects for decorative ceiling fans for indoor and outdoor use. Batteries are needed in telephone central to make sure that it operates also when mains voltage is cut and they also give very stable output voltage which is needed for reliable operation of all the circuit in the central office. Positive voltage is more commonly used in many electronics circuits, so it is easier to generate and electrolysis in telecommunications wiring is not a problem in typical environment inside office buildings. The cost and cabling required ruled out the idea of running a 4-wire circuit out to the subscribers' premises from the local exchange and an alternative solution had to be found. The frequency response is limited by the telephone transmission system (the actual wire from central office to your wall can usually do much more).


The current changes which the telephone's own microphone generates are not send to the speaker. Radio Shack's `Understanding Telephone Electronics` (copyrighted around 1985 I think) calls this effect sidetone and gives the impression that this was indeed intentional in order for the speaker to determine how loud they were speaking with reference to the called party.
The bell circuit is either designed so that it has high impedance in audio frequencies or it is disconnected from line when phone is picked off-hook. Pulse dialing is traditionally accomplished with a rotary dial, which is a speed governed wheel with a cam that opens and closes a switch in series with your phone and the line. Bell Labs developed DTMF in order to have a dialing system that could travel across microwave links and work rapidly with computer controlled exchanges.
When the circuit detects that a phone line has been cut, it activates a MOSFET which can be used to drive a relay, motor, etc.
Buy your new quality ceiling fan from Del Mar Designs This contemporary ceiling fan design from Possini Euro Design offers sleek, updated good looks. When your telephone is in on-hook state the `TIP` is at about 0v, while `RING` is about -48v with respect to earth ground. Typically the CO actually runs off of the battery chargers with the batteries in parallel getting a floating charge.
Placing a small DC bias on a long transmission pair is often done by telecommuncation carriers to reduce poor connections, and noisy lines. Hence, the 4-wire trunk circuits were converted to 2-wire local cabling, using a device called a `hybrid`. Touch-tone can therefore send signals around the world via the telephone lines, and can be used to control phone answering machines and computers (this is used in many automatic telephone services which you operate using your telephone keypad). A one-off exercise from Australian With this fun project you can easily change the look of your ceiling fan in minutes – any time you want! When you go off hook, and current is drawn, TIP goes negative and RING goes positive (I mean less negative).
In theory the hybrid circuit can separate all incoming oudion from the audio sent out at the same time if all the impedances in the circuitry (hybrids on both ends and the wire impedance in between) are well matched. The mostly used standard is one disconnect per digit (so if you dial a `1,` your telephone is `disconnected` once and if you dial `2` your telephone is `disconnected` twice and for zero the line is `disconnected` ten times) but there are also other systems used in some countries. Each transmitted digit consists of two separate audio tones that are mixed together (the four vertical columns on the keypad are known as the high group and the four horizontal rows as the low group).

So putting DC current through the cable sealed the connection and so improved the transmission. This means that there is about 8V voltage between the wires going to telephone in normal operation condition. As voice signals pass from the 4-wire to the 2-wire portion of the network, the higher energy level in the 4-wire section is also reflected back on itself, creating the echoed speech. The DC-resistance of typical telephone equipment is in 200-300 ohm range and current flowing through the telephone is in 20-50 mA range. The shortest duration in which a digit can be sent and decoded is about 100 milliseconds (ms).
