6.6.8 Line Test
Using the line test function it is possible to check and evaluate any
port-to-port connection defined between two nodes. The transmission link
between these nodes can include repeaters. Each repeater available on the
link is unambiguously assigned to a node.
The line test is used to detect a defective port, a fault that has occurred on
the transmission link between two ports or a fault between a port and
repeater. A fault between a port and repeater can have its cause either in
the repeater or on the link. The link test permits a connection error to be
localized.
