TTC 42219A HSSI Interface Adaptor

The TTC 42219A HSSI Interface Module (High-Speed Serial Interface) is an adapter card used with TTC/JDSU/Acterna Fireberd 4000 and 6000 series communications analyzers. It enables testing of high-speed data links—specifically HSSI frame relay circuits—from 56 kb/s up to 52 Mb/s. It supports features like Bit Error Rate Testing (BERT), high-speed DTE emulation, frame relay over multiple DLCIs, and network latency analysis.

Capabilities & Applications

• BERT (Bit Error Rate Testing): Verifies physical layer integrity of high-speed links.

• Frame Relay Traffic Generation: Can generate traffic across multiple DLCIs at an aggregate rate of up to 8 Mb/s.

• Line Speed Coverage: Supports testing of line rates ranging from 56 kb/s up to 52 Mb/s (notably for the Fireberd 6000 with the Frame Relay option).

• DTE Emulation: Able to emulate transmission equipment for troubleshooting routers, switches, and CSU/DSUs.

• Latency & Relay Testing: Helps characterize network latency and verify relay service functionality
