Managed Objects of Ethernet Passive Optical Networks (EPON)
draft-ietf-hubmib-efm-epon-mib-06

  Word-wrapping makes some of the tables difficult to read. The editors
  might want to think about a different way to present this information.

  If the value can exceed what can be represented in 32 bits, wouldn't a
  64-bit value make sense, both here and for objects below that are
  similarly capped? (I'm no expert in this technology, so there may well
  be a good reason for why this choice was made.)

Nit:

The document says:


   The Optical Line Terminal (OLT) is the server unit of the network,
   located at the Central Office (CO).

   The Optical Network Unit (ONU) is the client unit of the network,
   located at the Customer Premises Equipment (CPE).

This is a non-blocking comment, but I do wish to note that I find the
"located in" clauses above somewhat strange.  If the services which
make a CO are required by the OLT in some way, the document doesn't
note it in a way that was findable by me; similarly, that operation
of this doesn't seem to require that ONU be in CPE--presumably it
can be anywhere the ONU functaionality is needed.  The other
diagrams and descriptions of functionality seem fairly general.
