In the process of assembling a collection of hardware for a home lab, I wasn't
paying attention and picked up a 2521 router, with Token Ring as opposed to
Ethernet. (Actually, so do the two 2612s I have, but I digress.)
Not wanting this machine to go to waste, and not having dealt with Token Ring
before, I'm wondering:
1) Can the token ring adapter be plugged directly into the router, or is a MAU
required?
2) Near as I can gather, a TR cable is not wired like a standard ethernet
cable. Is the pinout the same on both ends of the cable, or is one end
flipped, like a rollover?
Thanks in advance...

1) NO, absolutly NO; you need a MAU or TR-switch to form your Token-ring
There is no way of "back-to-back" connecting on TokenRing

2) NO, the wiring is different from ethernet cabling, sygnaling is even way
more different.
Since you need a MAU, there is only one type of cabling to connect hosts.
There are despite TWO different types of connectors, the old archaic IBM
ones and RJ45
You can (with the correct wiring sheme) use simple RJ45 connectors and CAT-4
cable (or better)
And it is no problem to mix connector types at the ends (you can have a MAU
like this one -> http://www.tavi.co.uk/ps2pages/ohland/8228.gif
and have RJ45 on the other ends)
