Abstract
A digital modem is connected to a CBX in a network. Data is transmitted to the digital modem in a data field of synchronous serial data frames. The digital modem converts the data into a digital signal corresponding to a time sampled analog signal representing the data. The converted digital signal is communicated to a digital to analog converter for transmission on a telephone line. Analog signals received on the telephone line are digitized, and then converted to data in the digital modem.
