Using the Analyzer
Transmit Loopback Test Connection
Transmit loopback is both an interface configuration option and a test
connection.
Transmitted data is directed both out of the transmit connector and
internally (within the interface pod) to the measurement system.
The analyzer ignores external connections to the receive connector.
For E1 interface pods set for the transmit loopback interface
configuration, you can select either the BNC or RJ-48 (equipment, or line
connector) as the transmitting connector. For all other interface pods,
you can only transmit using the connector labeled Out.
External Loopback Test Connection
Typical applications for this type of connection include calibration, self-
testing, troubleshooting, and demonstrations. This is an out-of-service
test that runs independently of a network. The analyzer acts as both the
transmitter and receiver.
