                 "This object is generally intended to be used for the creation of 
                  a temporary inactive upstream row for the purpose of adjusting 
                  the SCDMA channel parameters of an active upstream row.  
                  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. 
                  2) Set the docsIfUpChannelCloneFrom field to the ifIndex value of 
                     the active row whose SCDMA parameters require adjustment. 
                  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.
                  Although this object was created to facilitate SCDMA parameter 
                  adjustment, it may also be used at the vendor's discretion for 
                  non-SCDMA parameter adjustment."
