Cisco Broadband Access Center 4.0
Product Overview
Cisco
®
Broadband Access Center (BAC) is a distributed, scalable application allowing for
automated flow-through provisioning of subscriber services and management of subscriber
devices. Cisco BAC provides a centralized and automated platform for service providers to control
and configure residential home gateways and the IP devices behind the gateways.
Cisco BAC automatically recognizes devices, assigns the appropriate class of service, dynamically
creates and generates device configuration files, and activates subscribers. Cisco BAC provides a
single device management platform to support multiple technologies including DOCSIS

PacketCable

, CableHome

, satellite, and Session Initiation Protocol (SIP).
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
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 tens of millions of 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 1 million devices. These DPEs can be combined in groups to provide redundancy
and load sharing. 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 35 million
devices with a sustained rate of hundreds of thousands of new devices a day.
●
Integration with current systems: Cisco BAC integrates with existing service provider
systems, such as billing systems, operations support systems (OSSs), and other customer
management systems, through a Java provisioning API. It can also notify interested
