Abstract
A stuff decision code word of multiple bit length is transmitted over a number of frames equal to the number of bits per stuff decision code word. Advantage is made of a unique word used for burst synchronization wherein a common code word is used for both stuff decision and burst synchronization. A hierarchy of bursts is established to identify the particular channel of information to which the stuff decision is associated.
Claims4
In a time division multiplexed (TDM) communications system wherein the incoming data rate differs from the TDM information rate and wherein the data to be transmitted is formed in bursts a method for transmitting the decision to stuff comprising the steps of:
- a. generating the complement of a stuff decision code word in response to a decision to stuff or the nocomplement of a stuff decision code word when there is no decision to stuff;
- d. distributing said code word over a number of frames in a burst from one station;
- c. transmitting said distributed code word;
- d. receiving said distributed code word;
- and
- e. detecting either the complement or the noncomplement of the distributed stuff decision code word.
