What is DOCSIS Provisioning of EPON?
DPoE and IEEE P1904.1 (SIEPON)
DPoE Interoperability and Qualification
DOCSIS Networks for Internet Access
More than 118 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) 9/19/2012 Cable Television Laboratories, Inc. 2012. All Rights reserved. 3

What is DOCSIS Provisioning of EPON?
9/19/2012 Cable 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

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 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 IEEE P1904.1 (SIEPON)
SIEPON “Packages”
9/19/2012 9
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
