Setting Alarms and Inserting Errors This section describes how to simulate error conditions, set alarms, and simulate network failures. To test the response of a network, you might need to simulate parity errors, send alarm signals, and simulate network failures. This type of testing is simple and convenient using the CTS850 SDH/PDH Test Set. To insert PDH errors, it is necessary to set the layer in the mux chain where anomalies, defects and failures will be inserted. Some errors, like CRC, are specific to a particular layer (in this case, 2 Mb/s Multiframe). Insertion of a layer specific error will not change the insertion layer. Layer selection is not limited to active tributary rates. See the example of a TRANSMIT, Defects & Anomalies menu screen for PDH at the end of this section on how to set the layer for PDH Anomalies, Defects and Failures. CTS850 SDH/PDH Test Set User Manual 3 185 Setting Alarms and Inserting Errors Simulating Error Conditions The specific errors the CTS850 simulates depend on the transmit rate and payload structure.

The errors available to insert depend on the Structure and Payload settings. Not all errors are available all the time. FAS Burst is defined in terms of M errors in N frames, rather than a rate.
