I may be a little lost here, but isn't MFC5C E1/R2 just plain R2-Digital ?
The fact that you have DNIS or not doesn't change it (in brazil was kind 
of weird, you had to have the proper number of digits or something like 
that), but from my memory:

E1/R2 - Line Signalling - TS 16, and ABCD bits
Register Signaling - Inband - with DTMF fwd and back (Compelled I thing 
was the term used).
