+ FUNCTION DESCRIPTION
+
+ This function creates a table called BytesUsed that holds the value that
+ describes the number of bytes required to hold one frame worth of data in
+ the WMF (non-IF2) frame format. Each table entry is the sum of the frame
+ type byte and the number of bytes used up by the core speech data for each
+ 3GPP frame type.
