We are having a very bad time trying to fix noise (or echo or whatever)
problems on our PhoneNet-based AppleTalk network.  Configuration is - 
	22 Mac Nodes
	1 NEC SilentWriter PostScript printer
	2 AppleTalk ImageWriter Printers
	~ 2000 ft of 22 gauge phone wire, all nodes using PhoneNet
	  or similar network connectors.

One or two nodes on the net will lose sight of the printer at times.  Often,
unplugging a machine from the backbone truck will cause another machine
to lose contact w/ the printer.  Outage occurs through the network, with
no rhyme or reason.  Right now, the machine closest to the printer (next
to it, in fact) cannot find the plasted thing!

Help.  1) Does anyone have any familiarity with sich problems
       2) What network analysis tools can you recommend for such a
	  problem?  Any hardware/software analysis products would be welcome.

I have Seer & NetCheck.  OI also have a copy of MacEcho from Simtel20, but it
refuses to run.  Any help w/ this program would be appreciated also.

Thanks for any & all help.  Mail or post replies, but be aware that this 
system seems to have some problems receiving mail (or has in the past.)
