I imagine you're talking about a TDM2400 here (you don't specifically mention, 
but 11 lines suggests that is the case) -- I would first check your gains and 
wiring; the TDM card shouldn't have any design issues which would cause 
crosstalk like this, and once the information is digitized it's impossible to 
get this effect unintentionally.  However it is trivial to have high gains 
(or improper attenuation) cause crosstalk on analog circuits, especially 
poorly wired cross-connects.
