encompasses secure management of CPE, including:

• Performance and status monitoring
Cisco BAC supports devices based on the TR-069, TR-098, TR-104, TR-106, TR-181, and TR-196
standards. This support includes Ethernet and ADSL gateway devices, wireless gateways, VoIP ATAs,
and other devices compliant with CWMP. This release also provides for runtime-extensible data models
to support any upcoming data-model standards or any vendor-specific data models.
