tdma Cs V42 Bis P1 Maximum Codewords

This attribute specifies the maximum number of V.42bis codewords the IWF supports. A codeword is a binary number that represents a string of characters in compressed form. V.42bis keeps a dictionary of codewords for each compression direction. Changes to this attribute impact the compression ratio for the encoder (component TdmaBc V42Bis attribute compRatioEncoder). Changes also impact the amount of memory used (more memory is used when increasing the attribute). The gain in performance obtained from the selection of a larger dictionary may be offset by the larger codeword size needed, and for certain types of data, better performance may be obtained by using a smaller dictionary. Changes to this attribute do not affect existing calls.
