We had some trouble with DEC transceivers, which look visually identical
to Interlan I've seen. Our technical people ordered a cable a fraction
larger diameter then what DEC specifies. It worked fine with 3Com screw-on
transceivers but when we first spiked in a DEC transceiver the cable
shorted. Our DEC FE thought it was a bad transceiver, or that we should use
a special drill (a la Interlan) to make the "hole". In a moment of
inspiration one of us noted that the "larger" cable was slightly oval
on the transceiver channel. Forcing the pin in a little farther
(with a small ball bearing under the spike screw) caused it to come
to life. No short; everything worked fine. We now have the "right" cable
but I thought the experience might be useful to some of you out there.
