1.Introduction
This Implementers’guide describes the ONT management and configuration interface (OMCI) for Multimedia over Coax Alliance compliant interfaces. Three new managed entities are defined, as well as several modifications to existing entities.*
2.Additions to existing sections of G.98
3.2 Rev 2.
2.1Additions to section
2 Abbreviations
Add the following abbreviations
MoCA Multimedia over Coax Alliance
2.2Additions to section 5.2
Add the following items to list:
“PPTP MoCA UNI”
2.3Additions to section 5.3
Add the following items to the list:
“MoCA Ethernet PM History Data
MoCA Interface PM History Data”
2.4Additions to section 6.1
Add the following lines to Table 1.
* As there are no published specifications of this interface currently, this material is being put forward as an implementer’s guide. The intention is that once such specifications are published, they will be considered for normative reference in G.983.2.
2.5Additions to section 6.2
Add the following figure and text at the end of the section.
“The MoCA UNI managed entity relationship diagram is shown in Figure 31g.
Figure 31g –Managed Entity relation di agram, MoCA UNI”
2.6Addition to section 7.1.3
2.7Modification to section 9.
3.New sections of G.983.2 Rev 2
Add the following sections.
7.3.122 Physical Path Termination Point MoCA UNI
This managed entity represents the points at the MoCA UNI in the ONT where physical paths terminate and physical path level functions (i.e., MoCA function) are performed.
Relationships
An instance of this managed entity shall exist for each MoCA PPTP port on the ONT. Instances of this managed entity are
created automatically by the ONT upon creation/deletion of a circuit pack that supports MoCA UNI functions.

7.3.123. MoCA Ethernet Performance Monitoring History Data
This managed entity supports the performance monitoring history data for the MoCA Ethernet interface.
An instance of this managed entity may be created by the OLT for each instance of the MoCA PPTP managed entity.
Table Y/G.983.2 Alarm list for MoCA Ethernet Performance Monitoring History Data B-PO N
*This numbering is used with the associated Threshold Data B-PON managed entity. Threshold Data counter 1 indicates the 1st thresholded counter, etc.
7.3.124. MoCA Interface Performance Monitoring History Data
This managed entity supports the performance Monitoring History Data for the MoCA interface.
An instance of this managed entity may be created by the OLT for each instance of the MoCA PPTP managed entity.
Table Z/G.983.2 Alarm list for MoCA Interface Performance Monitoring History Data B-PO N
*This numbering is used with the associated Threshold Data B-PON managed entity. Threshold Data counter 1 indicates the 1st thresholded counter, etc.
**Because these counters are in a multiple-entry table, and the thresholds are only a single-valued, the sum of counters in the table should be used as the trigger for the threshold AVC.
