You can run two types of circuit tests in Control Center: performance metrics (PM) and intrusive circuit tests. Once you run a circuit test, you can track its status and view the test results.
Performance metrics tests
You can run performance metrics tests on circuits without taking them offline. For this reason, performance metrics tests are called non-intrusive tests because they don't intrude on your day-to-day work activities. After you request the test, the test is run almost immediately.
Performance metrics tests are your first-line-of-testing defense. These tests check to see if the circuit is being overused or exceeding its bandwidth. If it is, you're probably experiencing latency and jitter and the problem could be with your equipment or our network.
Note: Performance metrics testing isn't available for DS0-level circuits. To schedule a test for a DS0 circuit, go through the steps to set up a performance metrics test as you normally would. After you enter the service ID for the circuit, you'll be prompted to schedule an intrusive test.
Intrusive circuit tests
Intrusive circuit tests require preparation and planning because they are more thorough. To run this type of test, we must take the circuit offline, which means it will be down temporarily. Consequently, these tests need to be scheduled in advance and you must provide a date and time for when they can be conducted.
