You're 100% correct.

Connect your router to one of the numbered ports (1, 2, 3, etc). Those are
the LOBE ports used for connecting workstations and other token ring
devices. Clear the token ring interface (clear int to0). The relays will
click (if it's a mechanical, not electrical, MAU) and your router T/R
interface will initialize and either come up or stay down. If it stays
down, then move the cable to the next port in the MAU and clear int to0
again. Continue until you find a port that will bring the router T/R
interface up/up (those MAU relays can get stuck sometimes in shipping)

If you're using an RJ-45 (the unshielded twisted pair) version of the T/R
MAU, you can use a Cat5 cable (since it is a straight-through cable)
successfully. The T/R pinouts are shown here (watch URL wrap):
