  Of course.  Dying gasp is supported on most switches that are typically classified as NIDs.

  For example, Cisco:

  Dying gasp is just a Ethernet OAM frame broadcast on (usually) all ports just before loss of power.  If anything, Ethernet had this first, and ONTs just included it into their standards.

I like the ANT because it has a small footprint with only 2 ports, it's passively cooled, it's very simple to operate, it's controlled centrally, etc. Unfortunately, when I reached out to Accedian, they insisted that the controller (which is required) started at $30k, which is a non-starter for us.
