Data transmission systems typically consist of a transmission channel and data circuit terminating equipment (DCE) at both ends of the channel, and in some cases, multiplexing equipment at both ends of the channel. The transmission channel may be a dedicated communication channel or may be provided by a data switching network, a telephone switching network or other types of switching networks. The input and output devices of a data transmission system are terminals or computers, generally called Data Terminal Equipment (DTE), and the data information sent by the DTE is generally a combination of letters, numbers and symbols, and each letter, number or symbol needs to be represented by a binary code in order to transmit the information.
