Danderman - 12/4/2007 5:18 PMI cannot say when a new chart will be available, but we know that MLM will dock with Zvezda nadir, not Zarya nadir.

There is no Research Module, its dead. In its place, the Docking and Cargo Module will be transported by Shuttle to ISS, and moved by the station arm to FGB/Zarya nadir. That would leave a configuration with DCM at FGB Nadir, MLM at Zvezda nadir, and Pirs at Zvezda zenith, resulting in 4 total probe and cone ports available for Soyuz and Progress on the Russian segment.

anik - 14/4/2007 1:25 PM3. DCM will have two docking units: one - for docking (with helping of SSRMS) to the nadir port of Zarya module and one (not two, as I said earlier, I am sorry) - for docking of Soyuz TMA spacecraft...

But this doesn´t increase the number of docking ports of the Russian segment of the ISS.

Let's put it this way, if Node 3 is installed, FGB Nadir becomes basically unusable, so DCM preserves a docking port for ISS. Note that when Pirs is relocated to Service Module zenith, a 4th probe and cone port will be available.
anik - 14/4/2007 11:25 AM 2. DCM weight (without cargo) will be about 8-12 tonnes...
I am having a hard time figuring this out. Assuming DCM carries NASA cargo of 1.4 tons, and also the MLM cargo (mass could be at least a ton), this would make this one of the heaviest cargoes ever carried by Shuttle. However, the SPP hull should not be able to support such a mass.
ShuttleDiscovery - 15/4/2007 10:51 AM Not unless you dock to Pirs, which will be on the zenith port of Zvezda after relocation, meaning four docking ports not three (whether the soyuz can actually do that i'm not sure!)
Given the capability of Soyuz to conduct a manual flyaround of ISS, I would imagine that a Soyuz could dock to a current port via Kurs, and then re-locate at a later date with a manual flyaround to Zvezda zenith.
