Abstract
A digital subscriber loop termination device, such as an office channel unit, dataport unit, digital data bank unit or the like, employs a microprocessor for providing data transfer between customer lines and network lines operating at respective different data transmission rates. The microprocessor circuit responds to network sync pulses for providing transfer of network input bytes to customer output generators and for providing for transfer of customer input bytes to network output serial generators. Additionally, the circuit includes facilities for enabling operation at different customer rates.
