Tektronix ST112 SONET Test Set
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.
Features:
- 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
