The Agilent/Keysight E4203A is a protocol line interface module designed for the Broadband Series Test System (BSTS), enabling test and analysis of fast-packet networks built on ATM and BISDN technologies. Operating at 155 Mb/s, this module supports ATM traffic management, signaling validation, and Packet over SONET/SDH testing. The E4203A integrates into the modular BSTS chassis to deliver protocol-level testing capabilities for telecommunications R&D, product development, field trials, and quality assurance. This product is obsolete.
