Software Regression Testing ST112 Portable Transceiver The portable ST112 transmission analyzer is on the leading edge of today's growing need for SONET testing. It's designed not only to support today's needs, but tomorrow's emerging technologies as well. The powerful ST112 is a compact single-unit solution for providing extensive SONET STSX-1, OC-1/3/3c/12/12c signal generation and analysis for tributary and network testing. Optimized for lab-based conformance and field-based installation testing, the ST112 extends SONET testing technology to ATM by delivering a clear channel STS-3c concatenated mapping in addition to the standard DS3 and VT1.5 mappings. The ST112 combines easy-to-use, powerful test solutions with user-upgradeable software to meet evolving SONET standards. Rugged, Portable Design with Powerful Features While its portable, lightweight transceiver design makes the ST112 an ideal SONET test set, its extensive DSX-1 and DSX-3 test capabilities also provide outstanding network payload drop tests. At less than 22 pounds, the ST112 is the single-unit solution for all SONET testing where portability and ease-of-use are important. Standard RS-232, GPIB and parallel printer interfaces, as well as VT100 terminal capability, provide the ST112 with complete remote control, display and printed report features. Simple to Use The following features make the ST112 simple to use:

Front-panel LEDs provide instantaneous identification of the operational

status and alarms

Built-in LCD screen displays test menus and results

AutoLink feature automatically resets receiver to match user-updated transmitter settings

VT100 terminal interface allows easy remote access to extended menus

Interruptible pause/resume aids completion of long test cycles

Upgradeable Software Evolve with SONET Standards

The ST112's advanced design enables the user to easily install software

upgrades. This feature avoids obsolescence and keeps the ST112 on the leading edge of the evolving SONET standards. Extensive SONET Test Capabilities The ST112's SONET capabilities include not only optical carrier generation, but also STS-3c/12c, DS3 and VT1.5 payload generation. Additional features include:

VT Channel Scan for testing VT mappings

Event sync (Opt. 07) provides output signals for deriving switch timing or

propagation delay from alarm conditions

Byte synchronous payload mapping for next generation DLC testing

Full error and alarm generation The ST112 Receiver analyzes the incoming optical signal and displays performance-monitoring information for the optical signal and payloads. TroubleScan Systematically Searches for Errors The ST112 has been carefully engineered to enable the user to work smarter, not harder. For example, the ST112 Receiver has a unique, time-saving feature called STS TroubleScan, which systematically scans the entire input signal and displays any detected errors and alarms on all payload envelopes.
