Request a bits-per-subcarrier measurement to be made.

A request for a bits-per-subcarrier measurement is made by setting this object to the value of 'measure'. Upon completion of the measurement request, the Access Node shall set this object to 'idle'.

The SNMP agent should allow initiating a bits-per-subcarrier measurement process only if there is no other bits-per-subcarrier measurement already running, and respond with an SNMP error (e.g., wrongValue) otherwise.

Note that a bits-per-subcarrier measurement is also performed during a line diagnostic procedure. This object provides an additional mechanism to fetch the bits-per-subcarrier data. This additional mechanism is provided so that bits-per-subcarrier data may be fetched without forcing the line into no power state. This is useful because the bits-per-subcarrier allocation may be adjusted at show time due to rate adaption and bit swapping.

The implementation of this additional mechanism for measuring bits per subcarrier is not mandatory.

The results of the bits-per-subcarrier measurement are stored in xdsl2LineSegmentTable. The status of the bits-per-subcarrier measurement is indicated by xdsl2LineCmndConfBpscFailReason.
