Error insertion (anomalies)

The following anomalies can be inserted in addition to those in the mainframe instrument:
Anomaly
B1 (STM-4, OC-12)
B2 (STM-4, OC-12)
MS-REI (STM-4)
REI-L (OC-12)
Table S-2
The insertion of errors (anomalies) or alarms (defects) are mutually exclusive. The action
selected first is active.
