# This library strives to be an implementation of the following standard:

# DPoE-SP-OAMv1.0-IO8-140807 - DPoE OAM Extensions Specifications

# This library may be used with PON devices for
# configuration and provisioning.

## Note on Deviations:

## Tibit endeavors to use DPoE OAM for not only communicating with DpOE ONUs,
## but also to communicate with the Tibit OLT Microplug.  In places where this
## document deviates from the DPoE standard for ONUs, Tibit has added a comment
