I'm not sure but I don't think so as I've just configured the card with:

span=1,1,0,ccs,hdb3
bchan=1-15,17-31
dchan=16
echocanceller=oslec,1-15,17-31

span=2,2,0,ccs,hdb3
bchan=32-46,48-62
dchan=47
echocanceller=oslec,32-46,48-62

Span1 is the one direct to provider equipement.
Span2 is thh one that was connected to HiPath and which is simply unplugged
