There's some info on DPL/DCS on Mike Blenderman's web site. The code is basically 23 bits, 9 of which are the 3-digit octal DPL code, 3 bits are always the value 100, and the rest are parity/check bits to insure against false decoding. It is usually sent as frequency-shift-keying of the carrier, with the same amount of deviation as PL would be. That's about all I remember. More to read on the web if you look for it.
