Re: Hmmmm......
said by phxmark  :Token ring would only die on a client cable or feed cable cut with the old STP BIG BLACK CONNECTORS using a passive MAU. The old shorting type connectors so that when it was unplugged the token would still get passed, but a cut was usually fatal to the ring. IME in the one token ring shop that I worked in, the weak point was at the NIC. Every packet had to pass through every NIC along the way. While the big square wall sockets were shorting, the DIX connectors at the NIC end were not. Even when the wiring was perfect, all it took was a single NIC's transceiver to fail to cause a similar (and harder to find) outage. And they did fail, too often for my tastes. IIRC that was still a weakness with the 16 Mbps UTP topology. |

I worked for an outfit that was deploying thinnet in the early 90s. It had all kinds of weak points. The off-the-shelf BNC "T" connectors used at each NIC led to lots of inadvertent disconnections. You didn't need a cut, a good tight kink in the coax was enough to compromise the transmission line. But it did save a bundle on hubs and star wiring installation costs. |

Old bus topology would have gone down as well. As far as I can remember it required a terminator on each end.
