Method and apparatus for monitoring bit-error rate
First Claim
1. A method, comprising:
- generating, by at least one processor, a test signal exhibiting a selected bit error rate (BER) distribution profile, the selected BER distribution profile defining a change in a number of bit errors in the test signal over time; and
providing the test signal as input to a test network.

Abstract
A test set for evaluating network performance is described, and which may include an output device, a processor, a power supply, a memory unit, and a control terminal. The test set may be configured to receive a user-entered selection of one of a plurality of different bit-error rate profiles and generate a test signal exhibiting the selected bit-error rate profile. The test set may also supply the test signal exhibiting the selected bit-error rate profile to a network under test. In addition, the test set may receive as an input, an output from the network under test. The output may include the test signal exhibiting the selected bit-error rate. The test set may evaluate the received test signal and determine the performance of the network in response to the received test signal exhibiting the bit-error rate. The test set may then output the results of the evaluation.
