Extended information
A broadband modem is a modem that uses multiple analog voice channel bandwidths to transmit data signals.
In a multi-channel carrier system, the nominal bandwidth of an analog telephone channel is 4kHz, and 12 voice channels together form a base group with a bandwidth of 48kHz (60~108kHz). The five base groups are The 60 channels together form a supergroup with a bandwidth of 240kHz (312-552kHz), and the 5 supergroups together form a 300-channel main group with a bandwidth of 1232kHz (812-2044kHz).
According to the different frequency bands occupied by broadband modems, there are base group modems, super group modems and main group modems.
Broadband modems are mainly used in computers and computers, where multiple low- and medium-speed data are multiplexed into high-speed data, and where high-speed data transmission such as digital secure telephone calls and document faxes are transmitted.
With the construction and development of digital networks, more and more digital channels are used to transmit high-speed data. It is economical, convenient and reliable. Therefore, the demand for broadband modems is not very urgent, and there is no obvious progress in research and development.
