Tpi model 82 dds test unit acterna
- Provides an effective tool to quickly isolate problems and minimize repair time
- Suits the field with its rugged construction, lightweight design and battery-powered operation
- Supports local loop BER and loopback testing
- Reports the following results: bit errors, errored seconds, percentage error free seconds, bit error rate, as well as receive signal state, data rate and line loss
Straightaway testing is similar to loopback testing. The Acterna 4WLL Service can transmit or transmit and receive a known test pattern toward each other simultaneously. This method helps to isolate problems between the transmit or receive sides of the circuit.
If problems still exist after running straightaway or loopback testing, it is possible that errors were introduced by another providers' network. Testing through to the far end can determine if the problem is outside the immediate network. By using two Acterna 4WLL Service Tester 82s at either end of the line, end-to-end tests - both straightaway and loopback - can be accomplished.
