Hello,
	I work for a large power utility and I am part of a group trying to
write the specifications for a new national control center. The old one
is obsolete, cannot be expanded and the computer models have been abandoned
by Control Data, which is on the verge of bankruptcy. So we try to incorporate
in our specs, as many standards as possible, we really need an OPEN system,
we don't want to repeat this 70 million dollars purchase every ten years.
	I read in 'Communications Week' that there is the equivalent of GOSIP
for the utilities industry. Nobody I know ever heard of that. Does anybody
know anything about it ? 
	We try to get hold of the standards but there
seems to be many organisations with competing standards, IEEE, X/Open, COS,
ANSI, CCITT, OSF. It is confusing. I would need the addresses of those
organisms to get those standards, I have to read them if I want to specify
them, don't I ?
	We have about 200 RTUS ( remote terminal units, data acquisition 
equipement in the field ) each of them communicating over a dedicated
line at 1200 bps at the present time. The telecommunications department
of our company is setting up a X.25 private network and pressures us into
putting our data acquisition on it. We need the age of the data to not
exceed 1 second for digital and 5 seconds for the analog. We don't know of
anybody having done that, no manufacturer has done it and they are skeptical.
Does anybody know about a similar experience somewhere ?
