	sorry for the continuation....I had a terminal glitch which sent
the message previous before its time....

(cont)
	6. I have empirically determined that a DELNI is sort of a .6 - .75 of
a repeater and have seen several successfully cascaded DELNIs as shown
in the configuration above in item #5 work with no trouble on a network with
both decnet and TCP/IP packets flying at a tremendous rate....

	7. I have seen stable networks with 3 cascaded DELNI's and NO DEREP's.

	8. I have NOT seen networks that function with 3 cascaded DELNI's AND
a DEREP....

	9. Configuration guidelines are just that, one should be willing to 
test 'illegal' configurations and verify whether or not they work - the specs
are VERY conservative, and in many cases (except were life and limb are in
danger) TOO conservative.
