TR-69 Breakdown
TR-69 Screenshots / Use-cases
TR-69 deployments, progress 2

3. Terms
CPE – Customer Premise Equipment or the device that is being managed. Examples: Wireless Gateway Router, VoIP Digital Adapter, NAS (Networked Attached Storage) Drive, Settop Boxes, etc.
ACS – Auto Configuration Server, management server for CPE. Part of the Service Provider’s OSS / BSS (Operational or Billing Support Systems)
XML – Extensible Markup Language. Set of encoding rules that is both human and machine readable.
SOAP – Simple Object Access Protocol, messaging framework for web services, uses XML as its message format.
RPC – Remote Procedure Call, built-in procedure that can invoke another process on a remote computer/network.
Data Model – Set of objects defined for management of a CPE.
SNMP – Simple Network Management Protocol, protocol for managing devices on IP network.
STUN – Simple Traversal of User Datagram Protocol through Network Address Translators (NAT)

4. What is TR-69? Technical Report defined by Broadband Forum
XML SOAP Protocol
Specification to remotely managed end user devices
Enables communication between Customer Premise Equipment (CPE) and Auto-Configuration Server (ACS)
Base Management Functions:
Auto-Configuration
Dynamic Service Provisioning
Software/Firmware Image Management
Status and Performance Monitoring
Diagnostics

6. TR-69 Remote Management of Home Devices on Private Network
STUN Server
STUN Binding Messages
IPTV STB
Wireless Home Gateway Router
Inform Messages
ACS
VoIP Digital Adapter
STUN Server enables ACS to send Connection Requests to devices in customers home that reside on a private network
STUN protocol used to provide public address and port to ACS

7. TR-69 Extensions What can TR-69 be used for?
Manage VoIP Analog Telephone Adapters, [DSL] Modems, Residential Gateways, IP Settop Boxes
Extensions define data models for different devices:
TR-98 – gateway devices (DSL modems w/ built in routers)
TR-181 – Device Data Model
TR-104 – VoIP devices
TR-106 – Baseline data model structure
TR-110 – reference model for VoIP configuration
TR-111 – encompasses remote mgmt (now obsolete, requirements incorporated in TR69 Annex G)

8. TR-69 Advantages/Disadvantages
Device Configuration, troubleshooting, firmware upgrades, user management, monitoring.
Enables Service Provider to offer dynamic services from a centrally managed instance.
Reduces truck rolls/support calls by ability to managed devices with more granularity, proactive monitoring, and automated processes.
Disadvantages
Must cross several layers of protocols and methods that must interoperate
Interpretation of the Technical Report by various manufacturers differs, no standard certification.

9. TR-69 vs SNMP
SNMP
SNMP is a simple method to monitor and receive traps for our devices
Uses Community String (SNMPv2) for authentication
Limited to the demarcation device within a subscriber’s home.
TR-69
CPE Wan Management Protocol is designed to provide a high degree of security and is scalable.
Basic security allows for less robust CPE implementations
Greater security for advanced CPE implementations
Prevents tampering with the management [transactions or] functions of a CPE and/or ACS
Prevent theft of service
