Need to find the correct MIB for a Cisco837 Router

[Jamie Dobbs]

I'm trying to get MRTG to graph the ADSL throughput (bps) of a Cisco837 
router. I've searched but haven't been able to find a MIB that work, I 
have tried:

Dialer0:public@<ip>
ATM0:public@<ip>
ATM0.1:public@<ip>
but none of these appear to return any data.
Can anyon offer any assistance?

Cheers

Jamie
