+ * The coded bits are reordered and interleaved according to the following rule:
+ *	i(B,j) = c(n,k) for k = 0,1,...,455
+ *		n = 0,1,...,N,N + 1,...
+ *		B = B0 +4n + (k mod 19) + (k div 114)
+ *		j = (k mod 19) + 19 (k mod 6)
+ *
+ * The result of the interleaving is a distribution of the reordered 114
+ * bit of a given data block, n = N, over 19 blocks, 6 bits equally
+ * distributed in each block, in a diagonal way over consecutive blocks.
+ *
+ * Or in other words the interleaving is a distribution of the encoded,
+ * reordered 456 bits from four given input data blocks, which taken
+ * together give n = N, over 22 bursts, 6 bits equally distributed in
+ * the first and 22 nd bursts, 12 bits distributed in the second and 21
+ * st bursts, 18 bits distributed in the third and 20 th bursts and 24
+ * bits distributed in the other 16 bursts.
+ *
+ * The block of coded data is interleaved "diagonal", where a new block
+ * of coded data starts with every fourth burst and is distributed over
+ * 22 bursts.
+ *
+ * Also used for TCH/F4.8, TCH/H4.8, TCH/F2.4 and TCH/H2.4 and TCH/F14.4 */
