Tektronix / Microwave Logic ST112 SONET Transmission Test Set

  • Complete Overhead and Bit Error Rate Testing (BERT)
  • Multiple Electrical Outputs for Four DS1, Six DS3/STSX-1
  • GPIB and RS-232-C Interfaces


The Tektronix / Microwave Logic ST112 SONET Transmission Test Set is an extensive SONET STSX-1, OC-1, OC-3, OC-12, signal analyzer and generator for tributary and network testing. DSX-1 ans DSX-3 Asynchronous Cross Connect Testing capabilities can be used independently or integrated with SONET testing capabilities. Designed for both field and lab use, the Test Set extends SONET Testing Technology by delivering a clear channel STS-3c and STS-12c concatenated mappings in addition to the standard DS# and VT1.5 mappings.

• OC-1/3/3c/12/12c Framing and Payload per Bellcore and ANSI Specifications
• Complete Overhead and Bit Error Rate Testing (BERT)
• Extended Control and Measurement Display via VT100 and RS-232 Support
• STS-3c/12c, DS3 and VT1.5 Payload Mappings
• User-upgradeable Software
• Unique VT1.5 Channel Scan and SONET Trouble Scan
• Standalone DS1/3 Test Capability
• Six DSX-3 or Six STSX-1 and Four DSX-1 Outputs
• Quick Setup for Automatic Configuration of Standard Test Modes
• AutoSeek (Automatic Detection of Receive Signal) and AutoLink (Receiver Follows Transmitter)
• Full SPE and VT Pointer Control
• Multiple Electrical Outputs for Four DS1, Six DS3/STSX-1
• Access to All SONET Overhead Bytes
• Data Communications Channel (DCC) Add/Drop
• Multiple Simultaneous Timed Alarms and Errors (for Software Regression Testing and Other Applications)

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

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.

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.

• SONET Network Element Testing
• Loopback Testing
• End-to-End Testing and Monitoring
• Path Provisioning and Performance Monitoring
• Software Regression Testing

InstraView™ Equipment Inspection

Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.
With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.

It's like having the store come to you!
