– Key Features
The J2301B integrates WAN, LAN, ATM, ISDN, and analog TIMS testing in a single platform. Optional interfaces expand capability for advanced ISDN, ATM, and additional measurement requirements. It functions as both a protocol analyzer and BERT test set, supporting multiple serial interface standards and digital carrier formats.
– Typical Applications
Network engineers and technicians use the J2301B for WAN circuit verification, LAN troubleshooting, protocol compliance testing, and link quality assessment on Frame Relay and ISDN networks. The combination of BERT and protocol analysis makes it suitable for both carrier-grade WAN diagnostics and enterprise LAN monitoring.
– Compatibility & Integration
The J2301B works with undercradles and side modules including the HP J2309B Ethernet/Token Ring undercradle and HP E4594A T1 Telco Undercradle. Supported modules include the HP J2904B ISDN BRI/ST Simulation/BERT Module and HP J2294D E1/T1 Interface Module, allowing customization for specific test scenarios.
