Send 1000 ping packets of length 1500 bytes. The process will
take 1000 seconds, which is approximately 17 minutes.
If the computer is running a Windows operating system, this is achieved
by typing:
ping –n 1000 –l 1500 <ipaddress>
where <ipaddress> is the IP address of the PTP 600 ODU under
test.
If the computer is running a MAC operating system, this is achieved by
typing:
ping –c 1000 –s 1492 <ipaddress>
where <ipaddress> is the IP address of the PTP 600 ODU under
test.

Record how many Ping packets have been lost. This is reported by
Command Prompt on completion of the test.
The test has passed if the number of lost packets is less than 2.
Test resistance at the PIDU Plus end of the drop cable
If the above procedures fail to diagnose the issue, there may be a fault in the wiring of
the drop cable that connects the ODU (or LPU) to the PIDU Plus. Perform this task to
test the resistances between the RJ45 pins.
Use the PTP drop cable tester (
Figure 8-4
) to make testing easier. This can be ordered
from
http://www.motorola.com/ptp/support
by selecting
Order Cable Tester
and
completing the order form.
NOTE
The values printed on the PTP drop cable tester are example values and
should only be used for guidance.
