The Wandel & Goltermann ANX is a network analyzer engineered for comprehensive testing and performance evaluation of telecommunications network infrastructure. Built on the legacy of Wandel & Goltermann’s 100-year history in communications test equipment, the ANX delivers protocol-specific analysis and traffic simulation capabilities across multiple network hierarchies. The instrument supports both legacy PDH systems and modern SDH/SONET backbone architectures, making it suitable for development laboratories, acceptance testing, conformance validation, and in-service network troubleshooting.
Technical Specifications
The ANX interfaces with multiple network protocol families:
• SDH/SONET: OC-3/STM-1 (single-mode, multimode, UTP)
• High-order PDH: E3, DS3
• Low-order PDH: E1, DS1
• Legacy interfaces: V.35, V.28, Token Ring IEEE 802.5
• ATM internetwork protocols
– Key Features
• Network traffic simulation and analysis via external software and interface modules
• Protocol support: ATM, SDH, SONET, PDH, and jitter testing
• Bit error rate (BER) testing and jitter generation
• Level, noise, and phase jitter measurements for FDM communication systems
• Personal computer integration for enhanced analysis and control
– Typical Applications
• Development lab validation of network devices and systems
• Acceptance and conformance testing for equipment deployments
• Functional testing in production environments
• Troubleshooting of operational network circuits
– Compatibility & Integration
The ANX operates as a modular platform, integrating with interface modules, external computers, and specialized software to enable full protocol stack analysis and network traffic emulation across multiple network tiers.
