The Agilent/Keysight J2298B is an interface module for ISDN Primary Rate Interface (PRI) T1 signaling, designed to generate, simulate, and monitor ISDN PRI signals on T1 lines. This module integrates into Keysight test equipment chassis to enable comprehensive T1/ISDN PRI network analysis, protocol troubleshooting, and equipment validation across research, development, and manufacturing environments.
– Technical Specifications
The J2298B interfaces directly with T1 digital transmission lines operating at 1.544 Mbps. The module connects to host test instruments via dedicated module interface slots within compatible Keysight chassis platforms. Specific electrical characteristics including impedance, bandwidth, and power consumption are determined by host system configuration.
– Key Features
• T1 interface for ISDN PRI signal generation and observation
• Direct connection to T1 digital transmission lines at 1.544 Mbps
• Integration with Keysight network analysis and test equipment families
• Module-based architecture for chassis integration
• Supports both live traffic monitoring and simulated network conditions
– Typical Applications
• Network simulation and T1/ISDN PRI condition testing
• Live traffic monitoring and performance analysis on ISDN PRI networks
• Protocol analysis through T1/ISDN PRI data capture and evaluation
• Equipment validation in R&D and manufacturing test environments
• Troubleshooting and behavior verification of T1-dependent network devices
– Compatibility & Integration
The J2298B is engineered for integration into Keysight test platforms supporting ISDN PRI T1 testing. Host systems must provide compatible module slots and appropriate software support for PRI functionality. Consult your system documentation to verify slot availability and driver support.
