11.10 CWMP
The CPE WAN Management Protocol (CWMP) is a messaging protocol designed for communication between the
CPEdevices and the management system. Specifications for this protocol are written by The Broadband Forum (formally DSL
Forum) in technical reports. The TR-069 specification defines the messaging format based on XML for communicating using
CWMP.
Previously, the discovery process and all NMS-supported operations used CLI or SNMP to communicate with the devices.
Now TR-069 operations can be performed on Comtrend CPEs and AT-iMG devices. Although not all operations are
implemented, there is a generic TR-069 client application implemented that can be used to execute any of the operations
described in the TR-069 specification.
To access this tool, select Tools > CWMP Browser. Refer to the following figure.

.If any devices managed using TR-069 have been discovered using the NMS, they will appear in the Device pull-down. The
Connection URL is the URL on the CPE the Auto Configuration Server (ACS) can use to initiate a connection. (This is done
when using the Comtrend or RG Boot Configurator.) Also, the IP address of the ACS (the NMS being used) must be
provisioned by accessing the device (using the client’s browser, for example). Error messages may occur if these are not
present.
The tabs and buttons follow the operations of the TR-069 specification.
