patterns (CRPAT), continuous jitter test patterns
(CJPAT), or the compliant supply noise pattern
(CSPAT).
– J-Proof. Also referred to as Layer 2 Transparency
testing. Select this test if you want to verify that an
Ethernet circuit can support a variety of control proto-
cols (such as CDP, VTP, STP, and RSTP).
Discovering another JDSU test instrument
Before you begin testing, you can automatically detect other
JDSU test instruments on the circuit and determine their capa-
bilities.You can then optionally configure key parameters for
your test automatically based on a discovered instrument’s
settings. For details, see
another JDSU test set” on page 21
Initializing the link for Ethernet testing
Initializing an Ethernet link involves specifying the settings
required to establish connectivity with another Ethernet
device on a circuit (link), such as auto-negotiation, flow
control, and speed and duplex settings (for 10/100 Ethernet
traffic only). You can also enter the pause quanta for trans-
mitted pause frames.
After specifying the link initialization settings, you are ready to
connect the HST-3000 (or HST-3000s) to an access element
on a circuit, and then turn the laser on (if you are testing 1G or
100M optical Ethernet).
– If you turned auto-negotiation ON, and another Ethernet
device is on the circuit, the HST-3000 and the device
automatically go through the auto-negotiation process.
After auto-negotiation is complete, an Ethernet link is
established, and idles are transmitted over the circuit.
