represented by a sequence of pulses by means of a line code ( baseband transmission), or by a limited set of continuously varying waveforms ( passband transmission), using a digital modulation method. the passband modulation and corresponding demodulation (also known as detection) is carried out by modem equipment

it may also be an analog signal such as a phone call or a video signal, digitized into a bit-stream, for example, using pulse-code modulation (pcm) or more advanced source coding ( analog-to-digital conversion and data compression ) schemes. this source coding and decoding is carried out by codec equipment...

subscriber connected to the same exchange, but long-distance calling across multiple exchanges required manual switching by operators. later, more sophisticated address signaling, including multi-frequency signaling methods, enabled direct-dialed long-distance calls by subscribers, culminating in the signalling

the growth of the pstn meant that teletraffic engineering techniques needed to be deployed to deliver quality of service (qos) guarantees for the users. the work of a. k. erlang established the mathematical foundations of methods required to determine the capacity requirements and configuration of equipment...
