Equipment under test

When using an in-line test connection, configure the affected port(s) for a full duplex, regenerator, or loopthrough interface configuration (according to the type of interface pod installed).

The disadvantage of the in-line test connection is that you need to break the link to install and remove the connection. Therefore, for networks that are already running live traffic, it is better to use a non-intrusive system connection, such as passive and T-piece test connections.

Non-Intrusive System Connection

A non-intrusive system connection does not affect the traffic on the link to which the analyzer is connected. A non-intrusive system connection is most useful because you can run in-service tests without interfering with the live system traffic.

There are two test connections available for the non-intrusive system connection:

∙passive

∙T-piece

The analyzer interface configuration options for a non-intrusive system connection are full duplex and receive loopback.
