Joseph,
You can't connect TR back-to-back, when a station is inserting itself in the ri
ng the first thing it does is to send the Phantom voltage to test the relay in
the MAU, if this fail the station won't be inserted in the ring. The RI and RO
can be terminated but I didn't bother, I just used a regular Cat5 crossover cab
le connecting the RI to the RO.

Is there a way to cross-connect 2 token ring routers back-to-back like an
ethernet crossover cable? I want to save space on my rack by not having to
mount a MAU. If I can connect 2 token ring routers back to back with a
custom-made cable, that would save me from having to use a MAU.
Does anybody have the wiring diagram for converting an 8-port MAU to 2x
4-port MAUs. I openned my IBM 8228 MAU once and it does not seem to be too
complicated. What stomped me was the RI and RO ports. I did not know how
to terminate it. Has anyone tried this before. Once again, the intent is
to save rack space. If a single 8-port MAU can be converted to 2x MAU, that
would save a lot of space. Multiply that with 8 pods, that's a lot of Rack
space saved.
Joseph
