• BERT test for PDH and SDH and error performance analysis per G821 G826 G828 G829 M2100 and（or）M2101; directly and automatically compare the test results with standards.
• Anomaly/defect testing: Tx-end transmitting anomaly/defect events and Rx-end receiving anomaly/defect events with record and statistics; recorded events displayed in chart and/or graphics and supporting filter selection
• Overhead testing: overhead emulating transmission and receiving analysis; two parts: general part (including J0/J1/J2/S1/V5/C2) and extended part (all the remaining overhead bytes except A1/A2 B1/B2/B3 )
• Pointer monitoring: generate G.783 pointer and NDF pointer; display pointer value in real-time; record pointer adjustment events (positive, negative and NDF)
• APS timing measurement: measure the network switchover time
• Round trip delay testing: measure the signal transport time from Tx to Rx
• Tributary scan: auto scan each tributary with the range optional
• Timing and synchronization testing：frequency accuracy test; pull-in range and pull-out range test
• Real-time optical power testing
• Voice monitoring: able to select any channel of SDH/PDH

• Easy operation: 10.4’’TFT touch screen, visible graphic display
• Simulated indicators: for current and history alarm and error status; indicator quantities and types can be automatically set based on tested signals and interface settings.
• Multi-task testing: multiple tasks can be created and deleted dynamically and freely.
• Clock interfaces: external clock Tx & Rx interfaces  
• Events record: large capacity for recording bit error and alarm events; events displayed in chart and graphics and supporting filter selection
• Data management: test results may be saved as HTML or TXT format or exported to U-disk or PC for viewing and printing
