The present invention describes a method and apparatus for reducing the access-delay and transmission latency in a system where a network terminal modem terminates to a network over a transmission media. In a network the processing of input data to be transmitted as processed data on the transmission media is synchronized with a time period when the transmission media is to be allocated for transmitting the processed data.
