Mr. Reyes:
Enclosed are the results from the Power over Ethernet GTP Interoperability testing performed on:
Linear Technology DC671
This testing pertains to the Power over Ethernet testing that was performed during the week of November 17,
2003.
There were no interoperability issues uncovered, during the testing process. If you have any questions about
the test procedures or results, please contact us via e-mail at ([email protected]), ([email protected]) or by
phone at (603) 862-0239.
Sincerely,
Andrew Losee

Interpretation
The DUT was observed to exhibit conformant behavior.
The DUT was observed to exhibit non-compliant behavior.
The DUT was observed to exhibit conformant behavior, however this behavior deviated from
previous compliant results. An additional explanation of the situation is included.
The DUT was observed to exhibit behavior that is not recommended.
From the observations, a valid pass or fail could not be determined. An additional
explanation of the situation is included.
The DUT does not support the technology required to perform these tests.
Due to testing station or time limitations, the tests could not be performed, or were performed
in a limited capacity.
Not tested due to time constraint of the test period.
The observed values of the specified parameter are valid at one extreme, and invalid at the
other extreme.
Results are for informative purposes only and are not judged on a pass or fail basis.

POINT-TO-POINT (PTP) INTEROPERABILITY TESTS:
Comments on Test Procedures:
Test #1.1.1 Link Speed Detection
Case 1: This test entails powering on the PSE separately and then connecting the link partner. The Power
Sourcing Equipment should be able to provide power to the Powered Device. A link should be established
between the two devices and traffic should be able to be transmitted between them. Refer to the following
tables for further information regarding the results from this test
Test #1.1.7 Power Request and Application
These Cases are designed specifically for devices that only support power.
Case 1: This test entails powering on the DUT separately and then connecting the link partner. The Power
Sourcing Equipment should be able to provide power to the Powered Device. Refer to the following tables
for further information regarding the results from this test.
Case 2: This test entails power cycling the Power Sourcing Equipment while the Powered Device is
connected. The Power Sourcing Equipment should provide power to the Powered Device. Refer to the
following tables for further information regarding the results from this test.
Packet Error Ratio Estimation
High Attenuation Channel: The two devices are connected to each end of the channel with a 10-meter
cable. The high attenuation channel is approximately 120 meters long. A number of ICMP echo requests
(Refer to the Ethernet Physical Layer Interoperability Test Suite: Appendix A Table A-1) are sent to verify
that traffic can successfully be sent between the link partners. For this test event 4,680,000 64byte packets
and 197,000 1518byte packets were transmitted between the link partners. The number of packets lost is
noted. Refer to the following tables for further information regarding the results of this test.

Channel Plots
Included with this report is a series of plots that provide a characterization of the channels
over which the testing was performed. The plots include the following items:
• Attenuation plots taken for each channel.
• Near end cross talk (NEXT) plots taken from both ends of each channel (Both the
DUT and the testing station). The DUT end is labeled as “Near End Crosstalk"
and the testing station end is labeled as “Near End Crosstalk @ Remote”.
• Return Loss plots taken for each channel, at the DUT and at the testing station.
The DUT is labeled as “Return Loss” and the testing station end is labeled as
“Return Loss @ Remote”.
