                  The recommended procedure is:
                  1) Create an inactive row through an SNMP SET using createAndWait(5).
                     Use an ifIndex value outside the operational range of the system.

                  3) Adjust the SCDMA parameter values using the new temporary inactive
                     row.
                  4) Update the active row by setting object docsIfUpChannelUpdate to
                     TRUE. This SET will fail if the adjusted SCDMA parameters are not
                     compatible with each other.
                  5) Delete the temporary row through an SNMP SET using DELETE.

	             The following restrictions apply to this object:
	             1) This object must contain a value of active(1) for active rows.
	             2) Temporary inactive rows must be created using createAndWait(5).
	             3) The only possible status change of a row created using
	                createAndWait(5) (ie notInService(2)) is to destroy(6).
	                These temporary rows must never become active.
