How Telephone Work?
|
|
|
|
The telephone handles two
types of information: signals and voice, at different times on the same
twisted pair of wires. The signaling equipment consists of a bell to
alert the user of incoming calls, and a dial to enter the phone number
for outgoing calls. A calling party wishing to speak to another
telephone will pick up the handset, thus operating the switch hook,
which puts the telephone into active state or off hook with a resistance
short across the wires, causing current to flow. The telephone exchange
detects the DC current, attaches a digit receiver, and sends dial tone
to indicate readiness. The user pushes the number buttons, which are
connected to a tone generator inside the dial, which generates DTMF
tones. The exchange connects the line to the desired line and alerts
that line.
