RE: 5394 => Frame Relay

A couple of suggestions:

The 5394-type controller is using SDLC as the protocol. Be sure the
routers are configured to bridge DLC traffic (it can't be routed). I'm
not sure what all is involved to do this, but the person that configured
the router will know. It may be extra software for the router which may
cost a little bit.

If your router supports it, implement DLC Switching (AKA: DLCSw) or DLC
"spoofing". This allows the router to answer the poll from the AS/400
and keeps those data packets off the network.

Good luck!

Subject: 5394 => Frame Relay

A question for the communications guru.

        We have three sites that are currently communicating via private leased
lines (paradyne to paradyne).  These sites have dumb terminals that are 
connected to an IDEA controller (5394 equivalent).  We have been trying
for 
months to get these sites onto Frame Relay. AT&T is saying that the
AS/400 
is not configured correctly because they don't see a problem on their
end 
or in the equipment (router, DSU, CSU) that they set up at the sites and
here.  That isn't the problem because we have another site (with dumb 
terminals and the same controller) that is up and running on Frame Relay
with an identical configuration.  The latest idea has been to configure
a 
single point to point line on the AS/400 and try to diagnose just one
site 
instead of two on a multi-point line. All of the lines are configured as
multi point SDLC lines on the AS/400.  In order to change the
configuration 
do I simply change connection type from *MP to *NONSWTPP?  Are any other
configuration changes required?  Does anyone have any thoughts as to why
these other sites aren't coming up? Traceroute shows that all of the
sites 
are hopping directly to our site.

Thanks in advance for any assistance.
