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
