To Connect to the System Under Test

A typical application for this type of test connection is testing the integrity of the system under test. The remote loopback test connection is similar to the network element test connection in its uses. However, while the network element connection tests a single element at a time, the remote loopback connection tests all network elements in the loop. Use this connection to monitor, capture, and transmit traffic.

The main uses for this type of connection are to test

∙continuity

∙mean cell delay

∙loop cell loss

Typically, you use a network element test connection to test any new element you add to the network. When the element passes all relevant tests, you change to the remote loopback test connection, and test to see what effect the new element is having on the other network elements in the loop. You can also use this test to identify a problem with a system that is offline.

Configure the affected port(s) for full duplex for this type of test connection.

In-line Test Connection

The in-line test connection is an intrusive system connection. A typical application for the in-line test connection is testing equipment when it is being installed. Using this connection, you don’t need to complicate your test with optical or electrical splitters and T-pieces.
