WHAT IS TR069?
It is a protocol for communication between CPE (Customer Premise Equipment) and an ACS (Auto
Configuration Server) that provides secure auto-configuration as well as other CPE management
functions within a common framework.
TR-069 stands for a technical report defined by the Broadband Forum that specifies the CWMP “CPE
WAN Management Protocol”. It commonly uses HTT P or HTTPS as transport for communication between
CPE and the ACS. The message exchange is using SOAP (XML_RPC) for configuration and
management of the device.
Last published version of the standard is amendment 2 (CWMP1.1). The core defines the protocol,
session establishment, message exchange structure, and Remote Procedure Calls.
WHY USE TR069?
Service Providers, using TR-069, can have one common platform to manage all Grandstream devices
and other CPEs, no matter neither the device type nor the manufacturer.
This common application was not easily achieved before due to CPE vendor’s proprietary mechanisms
for provisioning/management.
TYPICAL SCENARIO:

Last Updated: 11/2010
Previous graph shows a common customer installation. Whe re CPEs (Grand stream devices) are behind a
router/gateway and they connect to the ACS via TR-069 so they can get manage remotely.
Normally TR069 provisioning/management will be used by service providers in large scale deployments.
Therefore, units need to be initially provision with the ACS connection parameters before being able to
connect with the server. There are several ways to work this initial configuration as per-provisi oning
before sending unit to end user. However, Grandstream provides a redi rection/provisioning service called
GAPS that can take care of initial ACS parameters setup.
RPC METHODS:
The following table provides a description of supported TR-069 RPC methods by Grandstream devices.
Some models may have some extra methods (vendor-specific methods) that are not shown in the table
below. Please contact Grandstream for more information.

Sent by the ACS to find out about the methods supported by the device.
This method is used by an ACS to discover the device supported parameters.
When called this method return a list of parameter names on the device.
Depending on the method parameters this can be called for complete and partial
parameter paths on the device.
This method is used by an ACS to obtain the value of one or more CPE
Parameters.
This method is used by an ACS to read the attributes associated with one or
more CPE Parameter.
This method is used by an ACS to modify the value of one or more of the
device's Parameters.
Changes the attributes (modifiers) of the specified path. The path can be
complete or partial.
Adds a new instance of an object defined on the device.
Deletes an instance of an object defined on the device.
Reboots the device.
This method is used by the ACS to cause the CPE to download a specified file
from the designated location. Filetype supported by Grandstream devices are:
• 1 Firmware Upgrade Image
• 3 Vendor Configuration File

TR104 DATA MODEL:
This technical report defines the data model for provisioning of VoIP devices by an ACS using the
mechanism defined in TR-069.
All Grandstream devices are only SIP compatible, for this reason, only objects and parameters related to
SIP are implemented from the Datamodel.

WHAT IS THE SCOPE OF THE REMOTE MANAGEMENT?
• Auto-Configuration: This mechanism allows the Grandstream device auto-provisi oning at the time
of initial connection, and the ability to re-provision at any subsequent time. For initial ACS
parameters provisioning please refer to the GAPS redirection service.
• Firmware Management: TR-069 provides tools to manage downl oading of CPE software/firmware
image files. The protocol provides mechanisms for version identification, file download initiation
(ACS initiated downloads and optional CPE initiated downloads), and notification of the ACS of
the success or failure of a file download.
• Configuration or environment variables changes notification:TR-069 provides support for a CPE
to make available information that the ACS may use to monitor the CPE’s status and performance
statistics. This is done by defining the conditions under whi ch a CPE should actively/passively
notify the ACS of changes.
• Enabling / disabling features remotely: For example, VoIP accounts can be easily activated by
sending a TR-069 RPC. Additionally other more advance applications as pushing contents or
customizing the GUI can be done by using vendor parameters.
• Reboot: Grandstream devices can be rebooted by using the mechanisms establi she d by TR-069.
SUPPORTED PHONES AND FIRMWARE VERSIONS:
• HT50X, GXW40XX (1.0.3.10 or higher)
• GXV3140 (1.0.6.12 or higher)
• GXP21XX (1.0.1.26 or higher)
INTEROPERABILITY AND DEPLOYMENT:
• Service provider contacts Grandstream sales department to establish initial relationship and
provide both parties technical contact information.
• Service provider sends to Grandstream the requirement list and/or expected provisioning flow
chart.
• Grandstream works together with service provider and ACS vendor to get the test cases and
testing accounts.
• Testing and corrections.
• Initial deployment and verification.

WEBUI CONFIGURATION:
Normally ACS configuration setting s are pre-provisioned by the service provider or the Grandstream
device is redirected by our GAPS to the location where the service provider has each device configuration
file. However, we still have a graphic interface for easy testing and debugging.
The TR-069 related parameters are:
• ACS URL: URL of the TR-069 ACS, Grandstream device will try to connect and send messages
to this server.
• ACS Username: Username used for the HTTP authentication against the ACS.
• ACS Password: Password used for the HTTP authentication against the ACS.
• Periodic Inform Enable: Set the Grandstream device to start a new session after “Periodic Inform
Interval”
• Periodic Inform Interval: time in seconds where the CPE will initiate a new session against the
ACS.
• Connection Request Username: Username to authenticate incoming connection requests.
• Connection Request Password: Password to authenticate incoming connection requests.
