4.2 Monitoring a Patch Module from External Test Equipment
When monitoring a patch module from external test equipment, you can use the external test equipment alone
to monitor a patch module. Or, you can connect the external test equipment to a test module. This lets you
monitor the patch module with both the external test equipment and the test module. See
Section 4.1
for more
information about using external test equipment through a test module.
