Abstract
An analog data station terminal is described for use in a high speed data telecommunication system. The analog data station terminal interfaces a customer modem to the local telephone line for transmission of data at very high data rates, e.g., more than 9600 bits per second, with significant reduction in error rate. The analog data station terminal receives analog signals from the customer modem and converts then to a digital form that is compatible with the telephone system. The analog data station terminal also receives digital data from the telephone system and converts it to analog form for input to the customer modem. The formatting and reformatting of the data signals are performed synchronously with the telephone digital data network.
