An entry is created by setting this object to 'add (1)' : Adds an entry to the table. 'mod (3)' : This is used to modify an existing entry. 'del (2)' : This is used to delete an existing. 'outOfService (4)': Setting this object to this value takes the channel out of service or brings the channel 'down (2)'. The channel can be brought 'up (1)' again by setting the object to 'mod (3)'. If there is redundant configuration for the channel, an active channel can be deleted only after locking the channel.
