Cisco Broadband Access Center 4.1 

Simplifies Service Activation and Management 

Cisco

®

 Broadband Access Center (BAC) is a comprehensive network management solution that reduces time to 

market for new services and accelerates revenue. BAC simplifies service activation and management and allows 

providers to: 

● 

Automate configuration, provisioning, and management: Operators can easily roll out and manage 

network devices with flexible provisioning options for data, voice, and video applications over cable, IP, and 

mobile networks. 

● 

Scale to virtually any size network: Deployable in any size network, BAC has more than 60 million pieces of 

customer premises equipment under management today. 

● 

Lower operating expenses (OpEx): Increases operator efficiency and reduces network management 

problems. 

As service provider infrastructure increases rapidly in size and complexity, management systems that simplify the 

task of operating the network and its services become more essential. Cisco BAC addresses this need by automating 
the configuration and provisioning of subscriber devices based on the service provider’s business policies. Cisco BAC 

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 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 configures 

the device and activates the service. 

Cisco BAC is a fast, secure, and scalable system for provisioning tiered services on devices. It is designed for: 

● 

Reliability: Cisco BAC provides high reliability and high availability, supporting autonomous headends, 

multiple distributed device provisioning engines (DPEs), each of which includes its own data-caching 

repository, a Trivial File Transfer Protocol (TFTP) server, and a time-of-day (ToD) server. During central 

server outages or communication problems, Cisco BAC provides continued service to existing registered 

subscribers. 

● 

Scalability and performance: Cisco BAC can support up to 60 million devices in distributed deployments. 

Cisco BAC uses multiple distributed device management and caching engines to balance processing of 

device requests. A single DPE can support as many as 2 million devices. These DPEs can be combined in 

groups to provide redundancy, load sharing, and disaster recovery. Cisco BAC includes a central component 

called a regional distribution unit (RDU) to manage service requests and modifications. A single RDU server in 

conjunction with the appropriate number of DPE groups can support as many as 60 million devices with a 

sustained rate of hundreds of thousands of new devices a day.
