EPON in Cable Environment – EPON, SIEPON, DPoE

  1. 1. EPON in Cable Environment – EPON, SIEPON, DPoECurtis KnittleApril 20, 2012
  2. 2. DOCSIS Networks for Internet Access  More than 56 million DOCSIS cable modems (CMs) are deployed worldwide 1.3 0.6 1.8 1.9 4.4  Every CM, regardless of 2.9 10.2 0.85 17.8 4.1 manufacturer or cable 0.54 1.0 0.54 operator, is provisioned 3.6 1.6 according to DOCSIS specifications 0.5  Cable operators want to use the same Operations and Support Systems (OSS) with other access network technologies (i.e., EPON)2 Cable Television Laboratories, Inc. 2012.

  3. 3. Agenda What is DOCSIS Provisioning of EPON (DPoE™)? DPoE and SIEPON Interoperability DPoE and EPoC Version 1.0 specifications3 Cable Television Laboratories, Inc. 2012. All Rights reserved. Proprietary/Confidential 5/2/2012
  4. 4. What is DPoE?4 Cable Television Laboratories, Inc. 2012. All Rights reserved. 5/2/2012
  5. 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 5 Cable Television Laboratories, Inc. 2012.

  6. 6. DPoE Project Objectives Develop specifications for EPON devices to support1 DOCSIS network provisioning and service concepts Define additional functionality to support Ethernet2 services Facilitate multi-vendor interoperability36 Cable Television Laboratories, Inc. 2012.

  10. 10. SIEPON “Packages” 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 10 5/2/2012
  11. 11. SIEPON / DPoE v1.0 Relationship DPoE specs essentially build on SIEPON standard DPoE-SP-ARCHDPoE System DPoE-SP-OSSI DPoE ONU DPoE-SP-MEF DPoE-SP-MULPI PON DPoE-SP-SEC DPoE-SP-SEC DPoE-SP-OAM SIEPON DPoE-SP-OAM IEEE 802.3 DPoE-SP-PHY DPoE-SP-PHY11 5/2/2012
