1. A method for distinguising among a plurality of devices on a network or among a plurality of data elements, comprising the steps of:

  • assigning a sequence of two or more signals to a device or data element, where each signal in the sequence has a frequency, andat least one signal has a specific duration;

    orthe sequence has a time-specific pause between at least two adjacent signals;

    orat least one signal has a specific duration and the sequence has a time-specific pause between at least two adjacent signals;

    receiving one of the assigned sequences of signals;

    detecting the frequency and duration of the signals in the received sequence and time-specific pauses between adjacent signals in the sequence; and

    in response to the step of detecting, identifying the device or data element corresponding to the received sequence of signals.
