The Tektronix ST2400 STM-16 2.4 Gbit/s SDH/SONET Test Set allows you to upgrade your existing SDH test capabilities to 2.4 Gbit/s. It's the first truly compact, lightweight, and cost-effective STM-16 test set available. The ST2400 is payloadindependent; VC-3, VC-4, VC-4-4c, VT-12, and any other mapping are all supported from an external SDH test set. The ST2400 Transceiver features three operating modes to provide the flexibility you need to test today's advanced STM-16 and Wavelength Division Multiplexing (WDM) systems. The ST2400 also provides very cost-effective testing for STM-64 systems and is switchable for SONET capabilities. Three Test Modes; Active Through Mode. Allows overhead bytes to be overwritten while regenerating the received STM-16 payload. Defects and errors can also be added to the received signal prior to retransmission. You can set defects and errors continuously, single-shot, or repetitively with variable duration and repetition interval. This mode is especially valuable for testing framing synchronisation and protection switching, and for diagnosing system interoperability problems. Terminal (External) Mode. Allows out-of-service tests to be performed. Using any external STM-1 or STM-4 SDH test set, the ST2400 performs STM-16 level testing while the external test set analyses the dropped tributaries. Previous investment in test equipment is preserved. Standalone (Internal) Mode. Where payload testing is not required, or an external STM-16 signal is not available, the ST2400 can operate independently. An internally-generated 2.4 Gbit/s test signal provides full error performance analysis and reporting at the STM-16 level. Features. 155 electrical / 155/622 optical add/drop payload capability. Dual wavelength available with option for hybrid networks. Easily switchable to SONET OC-48. Special 1550 ±10 nm optics for WDM applications. Standalone mode provides STM-16 signal testing without additional test equipment Payload independent. Active through mode to simulate fault conditions on installed networks. Options.
