HP E4216A Frame Relay Test Software

The HP E4216A Frame Relay Test Software decodes and displays frames, as well as generating test traffic (with encoding and decoding of DL-CORE frames).

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. Traffic can be displayed with a live viewer, captured in memory, or logged to disk. Capture megabytes of traffic, or loop indefinitely and stop when a specified event occurs. For example, capture all traffic sent to a specified data link control identification and stop when a framing error occurs. Captured information can be analyzed off-line with a playback viewer.

This datasheet describes testing Frame Relay over ATM networks. The HP E4216A can execute on any of three hardware modules -- the HP E4209B Cell Protocol Processor, the HP E4206A T1/E1 Frame Processor, or the HP E4207A V-Interface Frame Processor. The traffic generation, triggering, filtering, statistics and LMI testing capabilities described in this datasheet are provided by the HP E4209B Cell Protocol Processor and HP E4216A combination. Refer to the "For More Information" section to obtain specifications describing the HP E4216 software's capabilities when used with either the HP E4206A or HP E4207A Frame Processors.

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. You can test both sides of an interworking function or device with a single BSTS since timestamps and statistics are synchronized between all modules in the chassis, allowing correlation of events and times between physical ports.

• Extensive PVC testing capability
• LMI decodes and emulation for Q.933 Annex A, T.617 Annex D, original LMI, and NTT LMI
• Extensive PDU editing capability
• High performance traffic generation - up to eight streas with individually-selectable distribution
• Powerful programming - simply link programs to the supplied library of test routines
• Runs on T1/E1 and V-Series Frame Processors and on CPP for ATM/AAL-5
• Can be combined with Frame Relay SVC decodes or LAN decodes
