Re: CPE/NID options

  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.
