QT-600 Ethernet
NetComplete® EtherASSURE™ Service
Assurance Portfolio
The Viavi Solutions QT-600 is a carrier-grade, scalable,
Ethernet probe that delivers the test and troubleshooting
capabilities required to confidently deploy Ethernet. An
integral component of the Viavi NetComplete Service
Assurance Solution, the QT-600 reduces operations costs
by streamlining the service turn-up process and rapidly
segmenting the network to quickly identify problem sources.
The detailed test results it generates let service providers confidently guarantee service-level
performance. Converting this information into proactive measures has a positive impact—
retaining customers and building loyalty while lowering operational costs by deploying fewer
technicians to remote locations.
The QT-600 works with the NetComplete EtherASSURE for automated and on-demand
test and results management. The QT-600 can characterize customer service performance
before handoff to the end customer. The QT-600 supports VLAN testing, multipoint and
point-to-point Ethernet services. Adding the 802.1q VLAN tag lets the QT-600 emulate
the end customer’s traffic and operate in a Q-in-Q or preserved VLAN environment.
Key Benefits
yy Carrier-class Ethernet probe
yy Simplifies error proof testing
yy Combines active and passive testing
and monitoring
yy Centralizes testing with automated
test access
yy Validate Ethernet services are turned up
according to service level agreements
(SLAs) optimizing long-term burn-in
testing from a centralized location
yy Troubleshoot and sectionalize issues with
Ethernet services using ping, traceroute,
802.1ag/Y.1731 loopback and linktrace, RFC
2544 and Y.1564 SAMComplete
yy Monitor network traffic, perform top N
analysis, capture traffic, and apply filters/
triggers to drill down into data and
pinpoint problems
Additionally, the QT-600 can control VLAN priority or IP priority settings using differentiated
services (Diffserv) and type of service (ToS) bits. This allows the generated traffic to take
on characteristics of the customer’s traffic patterns, eliminating the need for coordinated
dispatches to multiple remote sites to turn up service. This, in turn, reduces operational costs
and ultimately speeds up the service fulfillment process.

Y.1564 (throughput, latency, and frame loss as well as back-to-back
tests), service providers can rapidly turn up services and troubleshoot
and isolate faults remotely from a single location. Input parameters
for each QT-600 test are highly configurable for maximum flexibility
when troubleshooting.
The QT-600 can be placed into Loopback mode and can also
automatically loopback various edge and customer premises
equipment (CPE) devices. Running both Layer 2 and Layer 3 loopback

tests mimic real service mix by testing up to 16 streams and multiple
services simultaneoulsy. Once the tests are completed, the QT-600
automatically reports the quality of service (QoS) results pertinent to
the active transaction. Users can run up to 16 active tests concurrently.
For monitoring, the QT-600, working with NetComplete, provides a
flexible interface that intelligently reduces the traffic captured on

of nonvolatile cache. View captured data either using Viavi Examine
software or Wireshark®. For more in-depth troubleshooting, analysis,
and monitoring, the QT-600 displays data utilization trends that
include frame distribution statistics as well as broadcast, unicast,
and multicast frame counts over a 15-minute period. Tracking and
reporting topN statistics and displaying the worst offenders along
with setting filters lets users spontaneously and easily drill down

Carrier-Class Ethernet Network Probe
Built for carrier-class networks worldwide, the QT-600 has both NEBS
level 3 and CE Mark certifications. Its scaleable architecture includes
10/100 RJ45, 1000BaseT, and 1000 optical gigabit interface connector
(GBIC) testing interfaces to simultaneously run up to 16 active tests.
A centralized Element Management System (EMS) takes care of all
configuration requirements and an automated software upgrade
function allows the system administrator to specify all or a subset of
the QT-600 to upgrade in a single command.

Simplified, Error-Proof Testing
The QT-600, via its open eXtensibe Markup Language (XML)
application programming interface (API), seamlessly integrates with
the EtherASSURE Test OSS, providing centralized test creation and
management that ensures standardized, consistent test procedures
are followed, thereby reducing user error. Additionally, through
its scheduling capability, EtherASSURE can run repeatable test
campaigns at specific times and intervals to assess network and
service-level quality. Test results can be automatically e-mailed and
also can serve as a baseline for future comparison over time. Its
customer-to-QT-600 mapping function enables tests to be created
and run against customer services rather than against specific
