1. A method of transmitting data at variable rates over a communications link in predetermined time intervals, where each of the predetermined time intervals has the same duration, comprising:

  • receiving data for transmission over the communications link;

    detecting a first transmission rate for transmission over the communications link;

    providing data bits at the first transmission rate into fixed size data blocks, each fixed size data block having the same number of bits;

    transmitting over the communications link at the first transmission rate during one or more of the predetermined time intervals a first number of the fixed size data blocks corresponding to the first transmission rate;

    detecting a change in transmission rate over the communications link from the first transmission rate to a second transmission rate;

    providing data bits at the second transmission rate into the fixed size data blocks; and

    transmitting a second number of the fixed size data blocks corresponding to the second transmission rate during one or more predetermined time intervals.
