Cisco Broadband Access Center for Cable
The Cisco Broadband Access Center for Cable (BACC), formerly known as the Cisco Broadband
Provisioning Registrar® (BPR), makes it easy for service providers to deploy high-speed data and Voice
over IP services over DOCSIS cable modems and media terminal adapters. Cisco BAC for Cable builds
intelligence on top of the Cisco CNS Network Registrar® protocol servers to allow cable operators to
automate the subscriber-provisioning process.
Performance, scalability, and reliability were the design requirements behind this third-generation Cisco
BAC product. In addition, Cisco BAC includes a Java-based provisioning API, ensuring quick
integration with customers’ existing and next-generation OSSs.
The Cisco BAC includes Cisco CNS Network Registrar, Cisco CNS Address and Name Registrar, and
IPfonix Key Distribution Center. Cisco BAC supports PacketCable and DOCSIS standards.
Cisco Broadband Access Center (BAC) is used to provision subscriber data for the MTAs:
1. Broadband Access Center provisions subscriber data into the Cisco BTS 10200 Softswitch.
2. A phone call is placed over the service providers IP network, as shown in Figure 1-9, consisting of
the Cisco uBR7246vxr Cable Modem Termination System (CMTS), Cisco BTS 10200 Softswitch,
IP backbone, and the Cisco MGX® 8850 Trunk Gateway.
3. The Cisco MGX 8850 routes the IP-based call from the MTA to the PSTN.
4. As the call is processed, RADIUS messages are collected by the Record-Keeping Server (RKS) from
the Cisco uBR7246vxr router and the Cisco BTS 10200 Softswitch.
5. The RADIUS messages are mediated into a call detail record (CDR).
6. The CDR is then passed to an external billing system, where the record is rated and posted to the
customer’s account.
The Cisco NMS/OSS for Broadband Services solution also provides service assurance:
• Alarm notifications from the Cisco uBR7246vxr (CMTS) and Cisco BTS 10200 Softswitch can be
viewed on Cisco Information Center.
• Software image management and configuration can be accomplished using CiscoWorks Resource
Manager Essentials (RME).
• Diagnostics can be provided on the DOCSIS domain by using the Cisco Broadband Troubleshooter
and Cisco Cable Diagnostic Manager.
