VIAVI Fusion QT-600-10 10 Gigabit Ethernet Test Head and Carrier-Grade Ethernet Probe

The VIAVI Fusion QT-600-10 is a carrier-grade, scalable Ethernet probe for deploying, testing and troubleshooting Carrier Ethernet services such as business services and mobile backhaul. It is a component of the VIAVI Fusion / NetComplete service assurance system and works with both Fusion and EtherASSURE assurance and test systems to manage automated and on-demand tests.

The probe supports 10 GE through pluggable XFP interface modules and is designed for carrier-class networks. It can emulate end-user equipment and generate traffic that simulates customer traffic patterns, including VLAN, Q-in-Q and preserved VLAN environments, with VLAN or IP priority controlled through DiffServ and ToS bits. Connectivity and service turn-up can be validated with ping, traceroute, 802.1ag/Y.1731 loopback and linktrace, multistream, RFC 2544 and Y.1564 tests.

Loopback and sectionalization

In loopback mode the QT-600-10 can automatically loop back edge and customer premises equipment, including network interface devices (NIDs) and another QT 600 in the network. Running Layer 2 and Layer 3 loopback tests between two QT-600-10 units and out to the customer premises segments the network to show whether a problem lies inside or outside the service provider's domain.

Centralized testing

Integration with the EtherASSURE test and troubleshooting OSS allows tests to be created and managed centrally, scheduled at set times and intervals, and queued until resources are available. Results can be e-mailed automatically and used as a baseline for later comparison. A customer-mapping function lets operators run tests against customer services rather than specific probes. Passive monitoring functions include network monitoring, top N analysis and traffic capture with filters and triggers.
