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
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.
Because the Periodic Informs are initiated by the Mediatrix unit, they have no problem
passing through residential or enterprise NAT and firewalls.
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 the
Technical Bulletin - How to activate a licence on a Mediatrix
published on the Media5 documentation portal at
). However, it can
be enabled/disabled for a specific configuration via the Management interface.
TR-069 methods supported by the Mediatrix unit include:
