I cannot for the life of me figure out what you are trying to do here.
Why are you writing $((( at all?  Is _D_LowLevel a variable or a command
name?  Are you trying to write a pipeline of commands, or a bunch of
bit-wise ORs?

If you want a pipeline, use $(a|b|c).  If you want bit-wise arithmetic,
use $((a|b|c)).  If you want an unreadable mess, continue as you are doing.
