how is data retrieved from the telephone? the transmitter converts the sound waves to electrical signals which are sent through the telephone network to the receiving phone. the receiving telephone converts the signals into audible sound in the receiver.
Convergence
Signals.
Actually you have this backwards, the telephone lines can only carry analogue signals (voice band, 20Hz to 3KHz) not digital signals.The device that converts digital signals to analogue signals for transmission over telephone lines is called a phone MoDem(this stands for phone modulator demodulator). At the opposite end of the line it of course converts the telephone analogue signals back to digital signals.
Telephone signals that are made from the binary code, which originates from the base two numbers 0 and 1
Cellular telephone signals can travel up to 22 miles.
Both telephone and data signals can be received at the same time by use of a microfilter. This device increases the data-carrying capacity of the line without disturbing the telephone signals.
LAN stands for local area network, and has nothing to do with telephone communications. LAN has 2 purposes:1.allows multiple computers to use the same internet connection,2.allows local computers to talk to each other(exmaple: sending a file from your computer to you're sister's computer)A telephone uses analog signals, a LAN uses digital signals.
The network device that regenerates data signals without segmenting the network is a repeater. Repeaters are used to prevent attenuation of signals.
which term means to issue signals along a network medium such as a cable
Network Management signal
The signalling function of a telephone network is related to the transfer of control information between the different terminals, switching nodes and users of the network. Signalling functions can be divided into two types: Supervisory and Information Bearing. Supervisory signals indicate the status or control of network elements. Call alerting, call termination and busy tones are examples of Supervisory signals. Calling party address, toll charges and called party address are examples of Information Bearing signals.
