Top posted thread. I see no problem with it.
Is "in-line" posting OK? I "top posted" originally as that had become
the
pattern. Isn't there an RFC some where that says to be generous in what you
accept as valid, but be exact in what you send...
BTW is anyone here familiar with the Cisco 2612? It is
mentioned below
for those who wish to read further.
I'll tell you what I am now a lot more familiar with it than when it arrived
three weeks ago, but having been touring the West Pondia for two weeks not
as familiar as I wanted to be. The "Product Data Sheet" is here:-
http://www.cisco.com/en/US/prod/collateral/routers/ps259/product_data_sheet0
900aecd800fa5be.pdf
In brief it is a 1-U box a with a single 10Meg Ethernet port and a 4/16 Megs
token ring port as standard. It also has the usual Modem and Serial ports
for a Console. it has one network module slot, two WAN interface card (WIC)
slots, and one "Advanced Integration Feature" (AIM) slot. They are available
on E-bay for around $30-$40. It seems very popular with the CISCO home use
community and for Cisco Certified Network Associate (CCNA) training as it
runs a reasonably recent version of the CISCO software and so is useful for
practising the exercises that are part of these courses.
Mine has a basic rate ISDN card in one of the WIC slots. You can add extra
interfaces but looking at the table in the above manual many interesting
ones either won't work with the 2612 (which seems to be the smallest member
of the family) or are rather beyond my price range. However there are 8
(NM-8A/S) and 16 (NM-16A) port async modules which will work and look useful
for building a terminal concentrator.

Rob,
Which cable do you need. The token ring DB-9 -> RJ45 media
filter to go
from the 3174 to the 8226?
There are some here on E-bay:- http://www.ebay.com/itm/390474238769

Where can I either find this cable or a pinout?

I use a Cisco 2612 in my setup. There needs to be a Token Ring
concentrator between the 3174 and the Cisco. I use an
IBM 8226-001
from ebay. I forget what I paid but it could not have
been over $40
I don't think. The 3174 Token Ring output connector is a 9 pin
D-sub like a serial port and I use a small converter that has a 9
pin D-sub connector and an RJ-45 socket. It is a generic
item that
you have to open up and connect the two connectors
however you want
for your application. The connection diagram was on the
internet at
one time. I got this at a local hobby electronnics store that
burned about a year ago and I have no idea where to order such a
thing. Using standard ethernet cables to go from the
3174/converter
to the concentrator to the Cisco is not the perfect way
but it works
if the cables are kept as short as possible so the impedance
mis-match is not to bad. Good luck.
Buddy

Is a cisco 2612 what I need to bridge the token ring/Ethernet
networks? (it sounds like it comes standard with
Ethernet and token ring ports)...
Do I need something else also or does it go:
Terminal --> 3174 --> cisco 2612 --> Ethernet network -->
Hercules?

Bob,
I can check with my source on Monday to ensure the card
will work in
a -51r.
