Introduction

EPON (Ethernet Passive Optical Network) uses a passive optical network. DPoE (Data Over Cable Service Interface Specification (DOCSIS) Provisioning of Ethernet Passive Optical Network) specifications implement the DOCSIS service layer interface on existing Ethernet PON. EPON Agent component provides an abstraction layer known as DPoE Hardware Abstraction Layer.

• EPON Agent is a CCSP component that exposes TR181 parameters related to the DPoE ONU interface characteristics.
• EPON agent provides info like packet buffer capabilities to the DPoE System, the maximum rate at which OAM PDUs are transmitted on a link, and version of the ONU firmware etc.
• Maintains a TR181 data model XML file with dbus object path as /com/cisco/spvtg/ccsp/epon.
• Has a layered architecture similar to any other CCSP component.

•   Access Layer interfaces with the CCSP message bus
•   Receives any set or get calls and pass them onto the DML layer to manage the data which is in the request.
