HP E6278A Frame Relay SVC Protocol Viewer

The HP E6278A Frame Relay SVC Protocol Viewer test software decodes and displays signalling messages in order to functionally verify switched virtual circuit (SVC) applications.

The HP E6278A supports both real-time operation as traffic is captured, and an off-line mode whereby captured traffic is played back from memory or a file. The decoded English-language display uses the same terminology found in standards documents. Errors are automatically detected and highlighted on-screen, complete with explanatory messages. Protocol data units can be displayed with the live viewer, or captured to memory.

Triggers and filters help eliminate superfluous traffic and detect intermittent events -- increasing testing productivity by focusing on specific DL-CORE frames or ATM cells of interest. For example, you set up triggers to start capturing when a specified event occurs. Or capture all traffic sent to a data link control identification and stop when a framing error occurs.

Combine the HP E6278A with other modules from the BSTS's extensive range of line interfaces and test software applications to test both sides of a Frame Relay/ATM interworking device or function. Use the HP E4214 UNI Signalling and HP E4217 NNI B-ISDN Signalling test software packages to generate ATM signalling messages, route them to your interworking device, and then see their frame relay equivalent with HP E6278 Frame Relay SVC Protocol Viewer - real-time and all with one tester!

The industry-standard HP E4200/E4210 Broadband Series Test System (BSTS) is ideal for R&D engineering, product development, field trials and quality assurance. It offers the most transmission and protocol technologies on a single platform - with six powerful solutions for Frame Relay/ATM interworking testing. The BSTS also has LAN testing capabilities, making it ideal for testing LAN interworking via Frame Relay backbones.

• SVC decoding according to several variants
• Extensive real-time capabilities
• Can be used in conjunction with Frame Relay PVC Test Software
• Operates over any of the supported Frame Relay stacks
