You don't need DOC 3 for 20mb, I'm currently pulling 28mb on my DOC 2 modem just fine.
If that's the case I would be super happy, I would like to hear form Rocca though to be sure because in Cogeco land it's considered Doc 3. If your city is not upgraded you cannot get it.

Officially Rogers wants you to have a DOC3 modem for speeds 18mb and above, but I'm with Distributel ,and I've had my old 5100 for years it continues to provide from the lowly 5 or 7mb when I got it all the way up to the 28 today.
