CPE Management

CPE Management

CWMP provides many CPE management functions, which improve CPE operation efficiency and decrease network management problems. Main CPE management functions include:
  • Automatic configuration
  • File management
  • Status and performance monitoring
  • Fault diagnosis

Automatic Configuration

CWMP enables an ACS to automatically configure CPEs. When a CPE has set up a session with an ACS, the ACS automatically delivers configurations to the CPE. Automatic configuration parameters include:

  • URL: address of the ACS
  • Username: user name used by the CPE to set up a session with the ACS
  • Password: password used by the CPE to set up a session with the ACS
  • PeriodicInformEnable: indicates whether Inform messages are sent automatically
  • PeriodicInformInterval: interval at which Inform messages are sent
  • PeriodicInformTime: time when Inform messages are sent
  • ConnectionRequestUsername: CPE user name
  • ConnectionRequestPassword: CPE password

File Management

CWMP enables CPEs to:
  • Upload files

    A CPE can upload the configuration file and log files to the server specified by an ACS to back up important data.

  • Download files

    A CPE can use HTTP, HTTPS, or FTP to download web page files, configuration files, system software packages, patch files, license files, and any other files from a file server specified by an ACS. After downloading a file, the CPE checks the validity of the file and processes the file according to the check result. For example, if the downloaded file is a configuration file, the CPE automatically specifies it as the configuration file for next startup and sends the download result (succeeded or failed) to the ACS.

  • Currently, the CPE does not support file download using digital signature.

  • To download a file using HTTPS, the CPE must set up a Secure Sockets Layer (SSL) connection to the ACS.

Status and Performance Monitoring

CWMP enables an ACS to monitor the status and performance parameters of the connected CPEs. Performance and functions vary with CPEs. Therefore, an ACS must be able to identify performance of different CPEs and monitor configurations and configuration changes of each CPE.

CWMP allows network administrators to define monitoring parameters and obtain the CPE status and statistics using an ACS.


Currently, the CPE does not support the data model defined in TR-143 among all technical specifications that define status and performance monitoring.

Fault Diagnosis

CWMP enables an ACS to diagnose CPE faults using methods such as ping, traceroute, asynchronous transfer mode (ATM) loopback, and digital subscriber line (DSL) detection.
