1 TR-069 or CPE WAN Management Protocol (CWMP)
The Technical Report 069 (TR-069), also known as CWMP, is a Broadband Forum technical specification. This protocol can be used to monitor and update the Mediatrix unit configurations and firmware. In other words, when using TR-069, the Mediatrix unit can get in contact with an Auto Configuration Server (ACS) to initiate a configuration script transfer/execution and a firmware upgrade.
The first time the Mediatrix unit is connected to the network, it will attempt to contact the Auto Configuration Server (ACS), which is the entry point for the administrator. The Mediatrix unit will obtain the URL of the ACS using either the DHCP server with option 43 or by retrieving the information directly from the Customer's Profile. Therefore, upon start-up, the Mediatrix unit will contact the ACS, which in return will send the required configuration files and initiate, if necessary, a firmware update. This automated sequence is what is referred to as zero-touch, as the Mediatrix unit is automatically configured by the ACS according to the instructions given by the administrator without manual intervention on the unit.
The administrator can determine a schedule for the Mediatrix unit to periodically contact the ACS. These contacts will allow the Mediatrix unit to:
- verify if new configurations are available,
- verify if a new firmware update is available and
- send notifications for monitoring purposes.
Monitoring is achieved by regularly sending notifications to the ACS, through the mean of "Inform" requests, which can be:
- Passive: the information is sent according to the schedule.
- Active: the information is sent immediately when a parameter status changes, regardless of the periodic schedule.
Furthermore, the administrator can initiate a connection to the Mediatrix unit to perform immediate maintenance or monitoring. This will only be possible if the NAT firewall has been configured to allow communications initiated by the ACS.
The TR-069 protocol can be activated on units that are already deployed with a licence key (For more details on licences refer to How to activate a licence on a Mediatrix unit published on the Media5 documentation portal). However, it can be enabled/disabled for a specific configuration via the Management interface.
TR-069 methods supported by the Mediatrix unit include:
- SetParameterValues
- GetParameterValues
- AddObject
- DeleteObject
- Download
- Reboot
- Upload
- FactoryReset
2 TR-104
The Technical Report 104 (TR-104) describes the data model for provisioning of a voice-over-IP (VoIP) CPE device by an Auto Configuration Server (ACS) using the mechanism defined in TR-069. Configuring the TR-104 parameters in DGW allows you to enable or disable the provisioning parameters for VoIP CPE, such as calls statistics.
- The Media5 implementation of TR-104 is limited to the SIPEndpoint profile.
- Active notifications are not supported for all objects except when explicitly mentioned. (for more details request the Supported TR-069 Methods and Parameters document from your representative).
- Only FXS lines can be managed by the TR-104 profile.
- BRI, PRI or FXO lines are not supported by the TR-104 profile.
- A single voice profile is supported, it is instantiated by default. No creation or deletion of voice profile is allowed.
- Only a subset of parameters is currently supported.
- When TR-104 is used, it is highly recommended not to use other means of configuration (since TR-104 assumes some configuration).
3 TR-106
Technical Report 106 (TR-106) is the Data Model Template for TR-069-Enabled Devices. The configuration of the TR-106 Network Interface parameter in DGW allows you to specify the network interface to be used for the TR-106 LAN profile to report network statistics.
- If no network interface is configured for TR-106, i.e. the field is left empty under Management /Misc /CWMP , the Mediatrix unit will use the network interface configured under Management /Misc /System Management /Network Interface .
- If the network interface configured for TR-106 is set to All
, the Mediatrix unit will use the
network interface configured for contacting the ACS in the TR-106 Configuration
section of the
CWMP Configuration
table. The
TR-106 Data Model template can only be used if Root Element
is set to
Device
. Refer to Configuring the Report Network Statistics (Through the TR-106 Data Model)
.
Note
This parameter can also be set via Cwmp.RootElement.
The TR-106 Data Model template can only be used if the Cwmp.RootElement parameter value is Device .
4 TR-111
Technical Report 111 (TR-111) allows the remote management of home networking devices through NAT traversal mechanisms, as defined in TR-069 Annex G (formerly in TR-111).
The TR-111 parameters defined in DGW allows the activation and configuration of a STUN server, so devices behind a NAT can be reached .
5 Basic Tasks
5.1 Configuring the Access to the Auto Configuration Server (ACS)
Before You Start
The CPE WAN Management Protocol (CWMP) service must be started (under System /Services ).Steps
- Go to Management /CWMP .
-
In the CWMP Configuration
table, under the ACS Configuration
section, set the following parameters:
- ACS URL Config Source
- ACS Static URL
- username
- Password
Note
The username and Password fields are not accessible if you have the User or Observer access right. Also, the ACS Static URL field is only editable if the ACS URL Config Source field has been configured to Static .
- Click Apply .

5.2 Configuring the CWMP Establishment (TR-069)
Before You Start
The CPE WAN Management Protocol (CWMP) service must be started (under System /Services ).Steps
- Go to Management /CWMP .
-
In the CWMP Configuration
table, set the following parameters:
- Set Root Element to Device or Internet Gateway Device , depending on your configuration.

6 CPE WAN Management Protocol (CWMP) Parameters
Although the services can be configured in great part in the Web browser, some aspects of the configuration can only be completed with the MIB parameters by :
- using a MIB browser
- using the CLI
- creating a configuration script containing the configuration parameters
For more details on the following parameters, refer to the
Reference Guide
published the
Media5 documentation portal. The Reference Guide contains all the parameters
used in the DGW software with their description, default values, and
interactions.
