About HPNA Testing

If your OneExpert is optioned and configured to do so (and CPE support the HPNA protocol
over an Ethernet port), you can use your instrument to verify that HPNA networks are
operating within expected service quality metrics and users can set up pass/fail limits to help
simplify testing.
NOTE:
Some STBs (set-top-boxes) or RGs (residential gateways) do
not support HPNA traffic over the Ethernet port.
In the HPNA test, OneExpert connects to the HPNA network via CPE and communicates with
the HPNA network host to initiate the test. Each communication path between all HPNA
network nodes will be tested, letting users segment problem node paths, node-to-node
communication issues, and verify that the whole network is functioning correctly.
The capabilities of the OneExpert DSL OneExpert DSL's optional HPNA testing features include
the following:
Operational mode — This mode monitors the active network during its normal
y
operation and periodically updates statistics.
Network test mode — This transient mode performs a disruptive network test that
y
transfers a configurable number of packets across each unidirectional logical link in the
network and gathers statistics.
These features are available if the HPNA software option is enabled.
