Ho ho.  No.  Not quite right.  The DAA is to protect the network.  Period.
The equipment is on its own.  (Actually, it would not surprise me if some
of the commercial DAAs included protection for the equipment, but that is
*not* the purpose of a DAA, and I for one wouldn't depend on the DAA for
that.)  Some manufacturers do a better job than others on input protection
for their equipment.
