摘要： A method for communicating data is provided that includes receiving a plurality of bits associated with a communications flow and recovering data lost from a packet by retransmitting selected subrate data for a lost sample over a specified time period. The method may further include transmitting one additional subrate for each sample. All data is generally retransmitted in a configured time interval and the additional subrate for each sample is transmitted every twenty milliseconds. In still other embodiments, the method includes skipping over any subrates that have already been transmitted within a recovery interval. In one implementation of the present invention, if any subrates had changed and had already been transmitted within the time period, there is no retransmit operation performed. If a lost packet is detected for a sample already in recovery, the time period is reset and a recovery process is initiated again.
