Pursue The Opportunities Presented By New Realities

Evolution of broadband technologies is rapidly transforming from silo-based approaches - where each technology type is assessed separately - towards more holistic and service-based approaches and ´vertical´ service offerings.

Focus is shifted from technical metrics toward subscriber expectations and needs - subscriber QoE makes the real difference!

Use Case: Managing PON Networks Using Broadband Forum Standards

Abstract

Executive Summary

Service providers worldwide are driving the deployment of quadruple-play services over next-generation access networks. Whether the access network is purely optical or based on a mixed fiber/copper technology, the requirements for operation and maintenance are changing dramatically compared to pure digital subscriber loop (DSL)-based access.

The DSL Forum has taken steps to resolve this problem with the approval of Technical Report 142 (TR-142), "Framework for TR-069 enabled PON and fibre related devices." TR-142 defines how Auto-Configuration Servers (ACS) can remotely configure, troubleshoot and manage a Passive Optical Network (PON) optical network termination (ONT) with layer 3 capabilities using the Forum's existing CPE LAN management protocol, TR-069.

The Axiros AXESS solution platform supports TR-142 to the full extent and offers PON operators a centralized management of quadruple-play services. Based on Axiros AXESS, PON operators are enabled to manage TR-069 embedded optical network terminals (ONTs) using Broadband Forum standards. This allows roll-out of voice, high-speed data and video services by provisioning ONTs via TR-069 and streamlines operations by managing ONTs as gateways.

The Axiros AXESS solution platform (ACS, DHCP) for PON 

  • enables for zero-touch provisioning of ONTs
  • streamlines workflows to minimize human errors
  • gathers all available device information from the ONT (e.g. QoS and statistic information)
  • provides a central interface for customer service, engineering and marketing

Technical Summary

The Broadband Forum recommendation for PON access consists of a combination of OMCI for physical- and Ethernet layer management and TR-069 for higher
layers.

While OMCI (ONT Management and Control Interface) specification addresses ONT configuration-, fault- and performance management for GPON services at layer2, TR-069 protocol (CPE WAN Management Protocol) is perfect to complement OMCI (and related protocols) for provisioning and management of subscriber services based on layer3 and above.

The Axiros PON Management Approach

  • use OMCI for PON layer2 management
  • use TR-069 for anything above layer2
  • anything that could reasonably be implemented outside the ONT should be managed with TR-069
