`
` EXAMINATION
`BY MR. COHEN:
` Q. Good morning, Mr. Seifert.
` A. Good morning.
` Q. My name is Justin Cohen. I am representing the
`plaintiffs in this case, ChriMar Systems, Inc. and
`ChriMar Holding Company.
` Are you are familiar with them?
` A. I am.
` Q. Now, you've been deposed numerous times before;
`correct?
` A. Yes.
` Q. Do you know about how many?
` A. Between 10 and 20.
` Q. So you generally understand the process and the

`
` Q. In the AUI.
` And where does it have distinguishing
`information associated to impedance?
` A. Well, what distinguish -- the 78 ohms
`distinguishes it from, let's say, a 10BASE-T device,
`which would be 100 ohms.
` Q. But 10BASE-T plugs in with an RJ45 connector;
`right?
` A. Yeah.
` Q. And this plugs in with an AUI cable; correct?
` A. Yeah.
` Q. The 15 pin?
` A. But I don't know that at the other end of the
`cable, for example.
` Q. At the other end of which cable?
` A. Either cable. If I am presented -- if I am
`presented with a cable with -- with pairs of wires, I
`can distinguish among -- among 10BASE-T device --
`between 10BASE-T devices and AUI devices by measuring
`the impedance across selected contacts.
` Q. Can you distinguish 10BASE-T devices from other
`10BASE-T devices using the characteristic impedance?
` A. I don't think that's required by the claims.
` Q. Can you answer my question?
` A. Can I -- ask the question again?

` Q. Can you distinguish one 10BASE-T device from
`another 10BASE-T device using characteristic impedance?
` A. Using just the characteristic impedance?
` Q. Yes.
` A. I don't think so.
` Q. Is there another way that you could distinguish
`one 10BASE-T device from another 10BASE-T device based
`on distinguishing information associated to impedance?
` A. Sure.
` Q. How?
` A. I could distinguish a 10BASE-T device that had
`Bob Smith terminations on unused circuits from a
`10BASE-T device that didn't have Bob Smith terminations
`on the unused circuits.
` Q. Is that in your report?
` A. No, but you asked the question and I answered.
` Q. So your opinion is based on the characteristic
`impedance between AUI and 10BASE-T?
` MR. HAWKINS: Objection to form.
` THE WITNESS: I am saying that different
`Ethernet devices can be distinguished by the impedance
`that is used to terminate the lines.
`BY MR. COHEN:
` Q. And when you're talking about different
`Ethernet devices, you're talking about different types

`
`of Ethernet devices; correct?
` A. I am talking about different Ethernet devices.
` Q. But they're different types; correct?
` A. What do you mean by "different types"?
` Q. One is 10BASE-T and one is 10BASE5?
` A. They could both be 10BASE-T.
` Q. But you can't distinguish one 10BASE-T device
`from another 10BASE-T device based on the characteristic
`impedance; correct?
` A. Again, I don't believe that's required by the
`claims. I can distinguish one Ethernet device from
`another Ethernet device based on the impedance.
` Q. This is why I -- I am trying to understand your
`opinions as laid out in C-2.
` And as I read Element 31E, pages 6 and 7 of
`your C-2, what it sounds to me you're saying is that you
`can distinguish a 10BASE5 device from a 10BASE-T device
`based on the characteristic impedance, because a 10BASE5
`device using an AUI cable has a characteristic impedance
`of about 78 ohms, and a 10BASE-T device has a
`characteristic impedance of about 100 ohms; is that
`correct?
` A. Let me read this and make sure that's
`reasonable reading.
` MR. HAWKINS: And before you answer that, I'm
