What is TR-069

TR-069 is a BroadBand Forum (former DSL Forum) technical specification which defines an application layer protocol for remote management of customer-premises equipment (CPE).

TR-069 Data Flow

For more information see TR-069: CPE WAN Management Protocol.

Why do you need TR-069 support

  • Centralized scalable management system
  • Possibility to manage a wide variety of residential gateways and other network devices (STB, NAS etc.) in the same way
  • CPE devices located behind NAT
  • Ability to track changes on CPE devices
  • Unified and scalable method of software upgrade
  • Vendor-specific management methods and configuration parameters For more information see MR-230: TR-069 Deployment Scenarios.

TROL benefits

  • Design flexibility; no efforts needed to add customer-specific features
  • Tunable footprint and RAM usage
  • Modularity
    • Multiple data providers each responsible for management of certain hardware or software component
    • Flexible logic allows to combine data providers and shape a customer device data model
    • Data providers can be reused across customer product line
  • Internal memory management to speed up allocations and secure memory usage
  • Debug mode with run-time validation of all data structures
  • Both ACS and providers data validation according to the datamodel specification (type checking, value range, size)
  • Run-time modules addition/removal
  • Active and passive notifications, diagnostics, periodic Informs
  • Integrated file transfer support (HTTP, HTTPS, FTP)
  • Strong debug capabilities including CLI interface for precise client control
  • Uses Broadband Forum XML data model description
  • Ready-to-use data provider for constant values


TROL components
  • Application Core is responsible for application initialization, shutdown, configuration files processing, internal events and commands dispatch
  • HTTP Server handles TCP/UDP Connection Requests
  • CWMP Session manager provides support for CWMP protocol, RPC, Events and periodic Informs
  • Transfer Manager performs files upload and download
  • IPC Manager provides debug interface for communication with external applications such as CLI
  • Data Providers are responsible for interaction with customer hardware or software; each is responsible for a set of TR-069 management variables or subtrees
  • Data Model Manager performs communication with data providers, generates notifications and performs providers data validation
  • Persistent Storage Manager reads and stores software/firmware images and configuration files into persistent memory, e. g. flash


  • Written in ANSI C
  • Single-threaded
  • Build system is based on GNU autotools
  • Utilize POSIX API (sockets, file access)
  • Can run on Linux, FreeBSD, NetBSD, MacOS X, QNX
  • Dependencies are gSOAP, libc (uClibc, glibc), OpenSSL (optional), libfetch or libcurl, expat

Provided services

  • TROL porting to customer platforms
  • Integration of TROL with customer’s software
  • Validation of customer product for compliance with TR-069 standard


  • Replace gSOAP with optimized HTTP/SOAP library
  • Support TR-069 Amendment 4 features
  • SFTP and TFTP file transfer
  • Multicast file transfer


The TROL TR-069 Client is used in all new gateways of Tilgin and has demonstrated good interworking with ACS used by Tilgin’s partners and clients.
