The Spirent AT9020 is an ATM testing module engineered for E1 circuit validation within ATM-to-LAN internetworking, high-performance ATM backbone, and edge device scenarios. Operating at 2.048 Mbps over E1 interfaces with HDB3 line encoding, it delivers UNI 3.0, 3.1, and 4.0 signaling performance benchmarking for standards-compliant ATM switches. The module integrates Smart Signalling Technology and supports two or more ATM SmartCards functioning as the user-side of the UNI interface, enabling multi-card testing configurations.
