This table is used to initiate the OPT-REQ message for a given OFDM DS channel. The message and resulting tests and requirements are defined in the OPT-REQ TLV Encodings section of the MULPI Spec. To use the object the Operator or PMA Application uses the CM MAC address, the DsOfdmChannelCfgIndex, DsOfdmProfileCfgProfileId as the key to initiate a test. The specific tests that are defined in MULPI are accessed with the ProfileTest attribute. This attribute is a BITS data type and will allow one or more of the OPT tests to be configured to be performed by the CM. Due to the nature of the ProfileTest attribute one or more tests can be requested in a single message and thus different amounts of data need to be configured in order for the OPT Message to have the required TLVs. Some of these tests perform evaluations of thresholds or margins. To facilitate these evaluations by the CM, these values are defined in the test request or the OptMerThresholdCfg table.
