Can you provide a technical explanation why 56k leased lines are able to achieve more reliable speeds and superior quality?
The design of the telephone system is based on digital channels which carry 56,000 bps of bandwidth (called a DS 0). Each voice line and each 56k leased line is allotted a single channel within the telephone network. Voice lines are digitized at the end of the local loop; this digitization converts your voice, which it receives as an analog signal, into a 56,000 bps stream of data. At the other end, it is converted back into an audible analog signal. Modems work by converting the telco customer’s digital data to and from an audible analog form that can pass through the voice grade line. Unfortunately, the process is inherently inefficient and susceptible to damaging distortion; moreover, substantial complexity is required to compensate for telco equipment operating under the assumption that is carrying a voice call. To use an analogy, trying to send data across a voice grade line is like attempting to swim a river in the upstream direction. Consequently, modems can never utilize the wh
