9.2 BERT
BERT stands for Bit Error Rate Testing or BER Testing. The bit error rate is a key
parameter in assessing systems that transmit digital data from one location to
another (that is, systems such as radio data links, fiber-optic data systems,
Ethernet etc.).
9.2.1 Ports Setup and Status
The first step in running an application is to set up the port interfaces. This is
done on the Ports Setup screen, which also provides port status
information.
The setup options and status information related to the Fibre Channel
interface are described in a separate section:
FC Setup and Status
For applications also including an OTN interface, you can find a description
of the setup options and status information for OTN in the following section:
OTN Setup and Status
Refer to the sections relevant for your current port setup requirements.
