The Netcom AT-9045B Module DS3 is a single-port ATM DS3 module engineered for network traffic generation and monitoring on Spirent Smartbits test platforms. This SmartCard delivers DS3-rate performance with B3ZS line encoding and C-bit parity signaling, supporting multiple loopback modes and flexible clock sourcing. It enables high-throughput call-state testing at 800 calls per second per port, scaling to 32,000 calls per second across a 40-port test suite.
