Summary:

This supplement defines a test plan whose purpose is to verify interoperability between an OLT and an ONU in the G.983 series of Recommendations which refer to a Broadband Passive Optical Network (B-PON). When testing peer to peer interoperability, such as between SONET/SDH ADMs, both network elements are usually considered to reside at the same hierarchical level, but in a technology such as B-PON, with a master/slave relationship, it is more appropriate to evaluate interoperability relative to a baseline, or master, equipment. In this document, the OLT is regarded as the baseline equipment, against which the ONU is evaluated. This is not to be understood as an assertion that the OLT is necessarily right in the event of incompatibility, merely to reflect the reality that a network operator is likely to have OLTs in place and is interested in qualifying additional ONUs for use on these OLTs. From this perspective, the unit under test is an ONU.
