Dave:
I have done the connectivity to FR 2 ways.
1.  Total TCP/IP, using the Ethernet port on the AS400, Cisco routers and
MCI FR.  This has worked very well, but the support was only for PCs
connected, no dumb terminals.  I guess you could use a 5494 that connected
ethernet to the router  and then hang some dumb tubes off the twinax ports.

2.  SNA over RF using Motorola Vangurad family MP routers.  V35 connection
to the Vanguard, supporting dumb tubes hung off a 5494.

Both solutions work well.  The SNA over FR is more complicated to set up,
but once in place works well.  I guess the bottom line is how much SNA
traffic do you need to handle.  If you are only doin IP, I'd go for #1.  The
cost of the Vanguard routers may offset the savings of using the green
screens. If I were you, I'd keep it the same for each location, either all
TCP/IP or all SNA over FR.

Just my opinions, let me know if you have any specific questions.

Subject: WAN design


|I've got a project coming up where I will have the ability to completely
|renovate a client's LAN and WAN. I would like to get some input from all
|of you who may be using some of these topologies to see what seems to
|work best with the AS/400.
|
|First off, we will try to go TCP/IP over Ethernet as much as possible,
|replacing most green-screen terminals with PC's, but we will probably
|end up with a couple small sites using twinax terminals (1 terminal and
|1 printer that get used 15 minutes every other day is not what we want
|to try to support as a PC). My first thought is to put everything onto
|frame relay and use some routers to connect all the sites. Most sites,
|except the small ones, would probably get connected with a T1 line into
|the frame relay network. Could any of you shed some light on your WAN's
|and how you have them set up? Especially in regards to the routers (I'm
|green on them) and how you handle sending SDLC traffic across the frame
|relay network; I've read here about problems some of you have had in the
|past with SDLC over frame relay and I'm curious what solved the problem.
|
|We are also considering printing options. We currently have
|twinax-connected laser printers and a 6252 printer in place. We are
|thinking of replacing the twinax-connected laser printers with HP
|LaserJet 8000's with a MPI Blue Kit IPDS chip and a JetDirect card. We
|are also considering replacing the 6252 with something faster, such as a
|6262. What are you doing for printing to the laser printers? Should I
|use the MPI twinax cards as well or stick with a pure Ethernet
|environment? What are all of you doing for your high speed impact
|printing? Especially in a TCP/IP Ethernet environment.
|
|Sorry for the long post and all the questions, but I would appreciate
|any information anybody could provide. Please feel free to E-mail me
|directly at: dboring@shl.com .
|
|Thanks in advance!
