If I'm understanding you correctly, you say that the "remote functions" on 
the MIC work properly on your radio as long as the radio isn't in digital 
mode. They don't work for me and several others when the T2-135 installed. 
Do you have any idea why it is happening? So far, it sounds like my two 
radios (whichever one of the two I install the T2-135 in) and two or three 
others have the same symptoms. If the remote MIC functions work OK in your 
radio, there must either be some difference in the T2-135 itself or in the 
radios themselves.

The two radios that I have here are a new DR-135T Mk III that I've had for 
just a few days, and a Mk II model that I've been using for an IRLP node for 
about 10  months, in other words less than 12 months old.
