JDSU announced a new module for its test system aimed at use by technicians who troubleshoot and turn-up end-to-end Ethernet circuits.

JDSU’s J-Proof testing verifies transparent forwarding of Ethernet frames over switched Ethernet networks. When Ethernet passes over switched Ethernet networks, improperly configured network elements (routers, switches, etc.) can filter, or even drop, critical network transmissions, causing hours of troubleshooting and turn-up delays, the company explained. Delays are further complicated when they occur over third-party networks.

With J-Proof, carriers can turn-up carrier-grade Ethernet circuits with quality of service (QoS) and Service Level Agreements (SLAs) in environments that employ third-party networks.

“To make Ethernet carrier-grade, Ethernet control plane messages must be reliably exchanged between all equipment, regardless of where on the circuit the equipment is located,” said Jim Nerschook, vice president and general manager in JDSU's Communications Test and Measurement business segment.

J-Proof works with JDSU’s T-BERD/MTS transport network test products, the T-BERD/MTS-6000A Multi-Services Application Module and T-BERD/MTS-8000 Transport Module.

Features in the J-Proof Test Option include Ethernet frame transparency testing over VLAN and Q-in-Q; VLAN Priority setting to ensure control messages do not time out or get dropped; Cisco Proprietary Protocol Test to verify commonly-used Cisco VTP and CDP end-to-end; and GARP and STP tests that confirms registration and topology protocols. A powerful user interface with both easy Pass/Fail and granular results helps technicians quickly evaluate test results, as well as troubleshoot problems, reducing operational expense.
