HP E4214A 3.0/3.1 UNI Signalling Test Software

The HP Broadband Series Test System (BSTS) provides the broadest, most powerful, comprehensive and configurable range of signalling test capabilities for R&D functional testing, automated conformance testing, and regression testing. Integration with other test modules and software makes the HP's BSTS a complete signalling test solution that provides signalling emulation, call setup, call generation, and conformance testing to ensure that ATM call sessions are set up, switched and released properly -- even under heavy load conditions

The HP E4214 series of UNI Signalling Test Software is built according to full standards specifications without shortcuts, which means it will catch problems other test equipment may not detect. It covers four different flavours of UNI: 3.0, 3.1, 4.0 and Q.2931 as well as Q.SAAL and Q.2110. Companion signalling products tests PNNI, NNI, ILMI. Use the E4214A with the HP E4212A AAL Test Software to obtain additional traffic generation, capture filtering and real-time statistics capabilities.

Three key ATM signalling test applications are supported: Stimulus- response testing, and user or network emulation, helps speed up signalling functional verification; rigorous call generation; and facilitates testing of SVC-based services by setting up virtual channels so that applications can be tested over them.

Equipped with the HP E4214A UNI Signalling software, your BSTS can monitor signalling messages and verify their correct operation by capturing and decoding messages, or displaying them in real-time, with automatic protocol data unit error detection. It an transmit signalling messages and analyze the response to determine how a device or network under test behaves. Powerful layer 2 and layer 3 emulation means you can use the BSTS as a reference test system, a complete protocol library from the emulation machine speeds up customized test scripting.

Dual-port operation allows correlated capture and measurements to be taken on both physical interfaces. This permits the simultaneous analysis of signalling messages from both sides of a full-duplex UNI link.

Automatic error detection and isolation decode and display layer 2 SSCOP PDUs and layer 3 UNI signalling messages; validates layer 2 SSCOP and layer 3 PDUs. Complete explanatory messages are provided.

Smart PDU and message editors for SSCOP and signalling protocols are provided with built-in library for ATM Forum 3. & 3.1 variants as well as Q.2931, Q.SAAL and Q.2110. Build-in standard set of signalling SETUP messages with preset fields means that you can create messages with minimal effort.

The HP E4214 can emulate a network-side device, such as a switch. It can also emulate the user-side such as a network interface card.
