Broadband Access Center for Telco and Wireless (BAC-TW) 3.5 is a distributed, scalable application
allowing for automated flow-through provisioning of subscriber services and management of subscriber devices.
Cisco BAC-TW provides a centralized and automated platform for service providers to control, monitor, troubleshoot,
and configure residential home gateways and other IP devices such as femtocell devices and set-top boxes that
implement the Broadband Forum’s TR-069 standard.
In the Broadband Forum’s management architecture, BAC-TW acts as an autoconfiguration and communicates with
devices using the CPE WAN Management Protocol (CWMP). BAC-TW is fully compliant with TR-069 amendment 1,
including support for the Request Download and Factory Reset optional methods as well as any vendor remote
procedure calls (RPCs). BAC-TW has user-defined data dictionaries that allow it to support any device attribute.
Dictionaries for TR-069 (home gateways with or without modems, wireless, LAN ports), TR-098 (home gateways with
quality of service [QoS]), and TR-104 (voice over IP [VoIP]) attributes are supplied.
In addition to the autoconfiguration server functionality, BAC-TW provides device inventory, supports troubleshooting
and device diagnostics, and includes a file server for firmware upgrades.
BAC-TW has a Java northbound API that is consistent with WT-131. In addition it provides extension APIs that can
affect its behavior dynamically as it interacts with a device.
Cisco BAC-TW automatically recognizes devices, assigns the appropriate class of service, and dynamically creates
and generates device configurations. A flexible template language facilitates defining the configuration of a device in
terms of which device attributes are to be monitored and set to which values. The templates can refer to user-
defined properties, which can apply to individual devices or groups of devices. Groups can be either user defined or
built in, for example, all devices of the same type, class of service, or subscriber. This provides a scalable
mechanism for customizing subscriber services. The same language and properties are used to define rules for
triggering firmware upgrades. Bulk changes can be triggered by simply altering a user-defined property or class of
service definition.
As service provider infrastructures increase rapidly in size and complexity, management systems that simplify the
task of operating the network and its services become more essential. Cisco BAC-TW addresses this need by
automating the configuration and provisioning of subscriber devices based on the service provider's business
policies. Cisco BAC-TW allows service providers to implement either or both of the following workflow models:
●
Preprovisioning: Devices are assigned to subscribers and recorded in advance in the provisioning
application. When subscribers plug them in, Cisco BAC-TW automatically assigns the appropriate service
level and activates them.
●
Autoprovisioning: When subscribers self-register for service, subscriber devices are captured and recorded
in the provisioning application. Subscribers are required to register for service before Cisco BAC-TW
configures the device and activates the service.
