Re: NCNI

The NCNI can be used anywhere a FONBE can be used and that includes V6.1
systems.

You should be able to (subject to some rules)
1) Remote Site
        a) WP
        b) 1x8
      c) NCNI pair
2) Fiber Optic cable between remote and local
3) Local
        a) Everything you have now
        b) NCNI pair

This is just too hard for me to do in an e-mail. Your account representative

Subject: [foxboro] System upgrade paths...

Hello to all. This is my first time posting to the list so please excuse
me if I do something wrong.
We have a need to develop an upgrade plan for our current DCS system. We
currently have some hardware that is no longer supported by Foxboro
(WP51As), and next year, more will join that list (CP40A's). Our current
software is 6.1.1. 

I would like to develop a plan to migrate our system towards upgrade,
but I have some compatability issues. 

My first project to tackle is I have two WP51A remotely connected to our
system via DNBX, thicknet, and tranciever. The transciever is no longer
supported, nor is the WP51A. Both these stations are critical to our
process. We need them up and running. I want to replace both of these
WP51 with two AW51Bs (in lifecycle, but can buy me time) I have. I also
would like to upgrade this communication to either fiber or ethernet,
utilizing the NCNIs, etc. However, as I understand it, version 6.1.1
does not support this? From what Ive read I must be at 7.*+ to move to
this. Is this a fact? If that's the case, can I load 7.* on those two,
yet leave the rest of the system at 6.1.1? (I also understand that there
is a good possibility of backwards compatibilty not being there.)

I have thought about doing away with those two stations and just
increasing my Xwindow capability in the meantime. Currently both of
those remote areas have Exceed Xwindow access to the system, but they
are monitor limited and would need those extra stations.

Also to toss into the mix is the issue of our CP40As moving to being not
supported in Jan 2006. Does anyone have any experience in migrating from
CP40As to something newer? This may force my hand at software upgrades,
which affects hardware upgrades...well, you all understand how that
snowball starts to roll...

Just as most companies these days are, cost watching is rampant. So I
need to develop a way to get my system from what it is now, to an
updated system (Software 8+ ???) say 3 years from now, and try to spread
those costs out over that time. Obviously I do not want to move to
something, only to replace it all in 1-2 years, just in the name of
getting by.

I havent even decided yet whether to move to XP or stay Unix...//*cracks
open another can of worms*\\

Any insight is much appreciated. Once again, please forgive me if I am
not using this list properly.
