This section summarises technical specifications for operation of Multimedia Over Coax Alliance (MoCA) devices (“nodes”) using in-home coaxial wiring for transport of multimedia content. It describes the MoCA node protocol stack and physical network model.

Moca Component registers with the CR using config files and xml files. CcspMoCA.cfg specifies the datamodel. XmlConfig file is CcspMoCADM.cfg which in turn specifies DmXml is TR181-MoCA.XML
Has two modules:-
...
Data model south bound API(board_sbapi) calls HAL APIs which abstract hardware configuration and status fetching.
The implementation of HAL APIs depends on platform SDK because different SoC vendors have different implementations for Moca.
When dmcli command is used to get or set a value , cosa_moca_dml.c in middle_layer_src is invoked.

For eg: $ ./dmcli eRT getv "Device.MoCA.Interface.1.LinkUpTime" Component path is eRT.com.cisco.spvtg.ccsp.moca. Depending on parameter datatype (Bool/uLong/String) described in TR181-MoCA.XML, the corresponding API in ./middle_layer_src/cosa_moca_dml.c (here, Interface1_GetParamUlongValue()) is called and collects values for the query parameter from moca HAL layer through board-sbapi. |

Some example APIs are listed below:
