Why it takes so long to get data back from New Horizons

Does anyone know if the 2kbps/4kbps numbers are the transfer rate of actual data, or the link speed?

I would presume that there are checksums or other error detection/correction schemes involved - does anyone know if that's a good assumption? If so what schemes are used and how much overhead they have?

New Horizons is using a 1/6 rate Turbo code for forward error correction, meaning 5/6 of the data returned is redundant. Previous discussion: https://news.ycombinator.com/item?id=9890476
