DOCSIS Networks for Internet Access More than 56 million
DOCSIS cable modems (CMs) are deployed worldwide
Every CM, regardless of manufacturer or cable operator, is provisioned according to DOCSIS specifications
Cable operators want to use the same Operations and Support Systems (OSS) with other access network technologies (i.e., EPON)

What is DPoE?
5/2/2012Cable Television Laboratories, Inc. 2012. All Rights reserved. 5
Brings the mature systems and business processes of the DOCSIS OSS to EPON access networks
Enables full vendor/equipment interoperability – similar to CMTS and Cable Modems
Leverages existing technical and customer care knowledge base, systems, and processes
Developed by MSOs, CableLabs, and vendors
DPoE Project Objectives
5/2/2012Cable Television Laboratories, Inc. 2012. All Rights reserved. 6
Develop specifications for EPON devices to support DOCSIS network provisioning and service concepts1
2 Define additional functionality to support Ethernet services
3 Facilitate multi-vendor interoperability

Topology Resolution and Physical Layer Initialization
• Initial MAC layer initialization using EPON Multipoint Control Protocol (MPCP)
• Single LLID is registered for subsequent stages
Authentication and Encryption Initialization
• Downstream encryption using AES‐128
• Device authentication
IP Initialization
IP stack configuration using • IP stack configuration using Dynamic Host Configuration Protocol (DHCP)
• TFTP download of configuration file
Registration
• Registration of additional LLIDs depends on services
• Classifier, service flow, and QoS configuration using extended OAM (eOAM)

DPoE and SIEPON
SIEPON “Packages”
5/2/201210
SIEPON is standardizing three “packages”:
o North America (Package A)o Japan (Package B)o China (Package C)
External specifications provide additional requirements for operating EPON in specific environments:
o DPoE specs for DOCSIS environments
o Broadband Forum for DSL environments
SIEPON / DPoE v1.0 Relationship
DPoE specs essentially build on SIEPON standard
