HP E1696A 155 Mb/s ATM Optical Load Generator

The HP E1696A 155 Mb/s Four Port Optical Load generator is a powerful tool useful for determining the performance of ATM networks and switches. It is a single-slot VXI module for the HP E4200/E4210 Broadband Series Test System that can create traffic on four 155 Mb/s OC3-c/STS-1 ports with user defined payloads and traffic rates, in both SONET and SDH modes.

Each independent output transmits an ATM cell stream within a STS-3c/STM-1 payload. Outputs are 1310 nm (nominal) and exceed short-range transmitter specifications. The E1696A may be used alone, or with other BSTS modules. Up to eleven modules can be, cascaded in an HP E4210 Form-13 base (five in an HP E4210 Form-7 base) and synchronized for extensive load generation capabilities.

The HP E1696A makes an ideal test companion for the HP E4209 Cell Protocol Processor (CPP) since you can use the HP E4209 to generate up to eight streams of precisely-controlled traffic for detailed testing on one port while the HP E1696A generates un-correlated background traffic on other ports. Each background cell stream can have up to 100 channels of ATM traffic.

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 supports the widest variety of standard interfaces of speeds up to 622 Mb/s, the broadest, most powerful range of signalling capabilities, the industry's most complete automated conformance test suites, time-savings features for monitoring, emulation, simulation, load generation, performance and automated testing.

Line interface modules can perform physical layer testing with a minimal BSTS configuration consisting of a line interface module and chassis.

Complete range of test software applications and dedicated test modules is available to perform upper layer testing.

Add the HP E4209 Cell Protocol Processor provides monitoring and simulation test functions at the ATM and adaptation layer by executing optional protocol testing software applications. The CPP performs many functions in hardware that are usually done in software -- such as an automatic segmentation and reassembly engine for sophisticated real-time ATM, AAL and other higher layer protocol testing.

The HP E4219A ATM Network Impairment Emulator module lets you find the limits of performance by inserting impairments into an ATM cell stream.
