FDDI advice - HECnet

10 Oct 2013

The DECconcentrator900TH has twelve FDDI twisted pair ports.

If someone is interested I can send the latest Digital Networks product catalogue (pdf)
where the GigaSwitch and DEChub900 modules are shown.

 The original one is the DECbridge 500, a 3U rack mounted device, 3 or 4 cards, 3
Ethernets (10 Mb/s) to FDDI. See the DTJ issue I mentioned in
my previous note.
...

 The other two: the DECbr idge 900, which plugged into the 900 series modular
enclosure. It's about the side of a 400 page hardcover book,
FDDI to 6 Ethernet ports, 60,000 packets per second using a MC68040 at
25 MHz. I'm still proud of that. (I wrote the "fast path" packet
forwarding firmware.)
...

 Then there is the Gigaswitch, a large modular chassis with lots of line cards, some
FDDI, some Ethernet, possibly some with other stuff I
don't remember.
...

 paul I meant to say that I have a DEC VNswitch 9 00XX plugged into a DEChub
One MX - there are clearly modular parts to that, but I'm presuming
there isn't a FDDI copper module that I would be able to use?

Thanks, Mark.
