Using the Analyzer
To Connect to the System Under Test
2-4
The network element connection is an out-of-service test, that is, the
system is not live. Use this connection to check things such as
•
protocol transfer and conversion
•
connection verification
•
quality of service parameters
•
policing mechanisms
Configure the affected port(s) for full duplex for the network element
connection. If you use the receive loopback configuration or the recovered
clock timing source, make sure the network element transmitter is
synchronized to an independent timing reference (to avoid problems that
may be caused by possible clock failure).
Remote Loopback Test Connection
The remote loopback test connection is an out-of-service test, that is, the
network is not live. The analyzer generates and receives all system traffic.
