If another table is indicated a further code prefix is located in the input stream and the further lookup table is accessed in accordance with the further code prefix.
The DPE analyzes the input string to identify which call formats, code prefix, and/or Supplementary services apply to the call.
If the code value is valid, the number of bits is selected and appended to the code prefix to form a code word which is later decoded by the system of the present invention.
A code prefix is located in the bit stream and used to determine a number of bits to be selected from the input bit stream according to an access of a code book.
Additionally, a pointer, directing access to a different code book, may also be indicated by the access of the first code book according to the located code prefix.
A marker code is associated with each code book, and is indicative of the length of the code words in that book.
