商品簡介
Thompson (telecommunications, U. of Pittsburgh) describes telephone switching system technology in a context of history, regulation, services, and modern communications. The design of large-scale architecture is the main focus and the material is organized into sections on fundamentals; analog systems such as the step-by-step, crossbar, and electronic switching systems; digital systems; broader issues such as the interaction of humans with the systems and the breakup of the Bell system; and evolving systems such as wireless telephony, new tethered technologies, and photonics.
