Introduction
Cisco Broadband Access Center (Cisco BAC) automates the tasks of provisioning and managing customer premises equipment (CPE) in a broadband service provider network. The product provides a simple and easy way to deploy high-speed data, voice technology, and home networking devices.
With the high-performance capabilities of Cisco BAC, you can scale the product to suit networks of virtually any size, even those with millions of CPE. It also offers high availability, made possible by the product's distributed architecture and centralized management.
Cisco BAC enables you to provision and manage CPE by using the Broadband Forum's CPE WAN Management Protocol (CWMP), a standard defined in the TR-069 specification. Cisco BAC integrates the capabilities defined in TR-069 to increase operator efficiency and reduce network-management problems.
Cisco BAC supports devices based on the TR-069, TR-098, TR-104, TR-106, and TR-196 standards. These devices include Ethernet and ADSL gateway devices, wireless gateways, VoIP ATAs, DLC, and other devices that are compliant with CWMP. For details about the features supported in Cisco BAC 3.8, see New Features in Cisco BAC 3.8 section.
System Components
Cisco BAC comprises:
•
•
•
•
Cisco BAC into an existing operations support-system environment. You can use the provisioning API to register devices in Cisco BAC, assign device configuration policies, run CWMP operations on the device, and configure the entire Cisco BAC provisioning system.•
•
•
System Requirements
You must have the Solaris 10 or 11, or Linux 5.x or 6.1 operating system installed on your system to use the Cisco BAC software. For information on installation, see the Cisco Broadband Access Center 3.8 Installation Guide.
Licensing Requirements
You require a valid license key to successfully provision devices that use Cisco BAC. These licenses are specific to the:

New Features in Cisco BAC 3.8
The new features of the Cisco BAC 3.8 are as follows:
•
•
•
•
•
Non-Root User Support
This feature allows a non-root user to run Cisco BAC on Solaris or Linux server. The non-root users and associated groups should be created prior to the installation as these details are required during the installation. A non-root user can run all the Cisco BAC components, RDU, DPE, CNR extension points, CAR extension points, and STUN.
Asynchronous Mode for Device Operation
Asynchronous mode facilitates the RDU to execute the asynchronous immediate operation without reserving a PACE thread for the complete operation. The TR-069 IPDevice operations GetParameterValues and GetParamValues RPC can be performed with this mode. This feature increases the RDU efficiency in serving more number of API operation requests.
Scriptable DPE Extension Support
This feature introduces the Scriptable extension service which facilitates running the java scripts based DPE extensions. When the CPE boots and attempts to establish connection with the DPE, the extension scripts will be executed at the following extension points:
•
•
•
•
These extensions can be configured in the device property hierarchy at Class of Service (CoS), Device, Group, Provisioning group level, and CWMP defaults.
For unregistered devices, the extensions can be configured from the Admin UI at CWMP default level.
These extension scripts are added in the RDU database from the Admin UI or from the API client. The following types of extension scripts are added in the RDU database:
•
•
Once the extension scripts are added in the RDU database, the RDU pushes the scripts to the DPE cache. When the CPE boots, and attempts to establish a connection with the DPE, the DPE invokes the scriptable extension service and executes the extensions configured on the device property hierarchy.
This feature also provides the support to load and unload the extensions dynamically without restarting the DPE.
TR-196 Support
This feature introduces the TR-196 support, which facilitates Cisco BAC to support the TR-196 data models or TR-196 provisioning logic. Cisco BAC template-based mechanism which helps in assigning configurations for devices, is enhanced to support the TR-196 devices in the service provider's network. Cisco BAC provides two additional parameter dictionary files to support the following TR196 data models:
•
•
This feature also provides Generally Available (GA) scriptable extensions targeting the residential 3G features of the TR196 data models. In Cisco BAC device property hierarchy, service providers can use the custom properties to configure the extensions and the TR196 data model to be used for any device.
TR-196 support provides the ability to configure additional contents of all extension events, that helps to stop querying the BAC RDU to lookup for additional data.
The support for discovering multiple object instances associated with a parameter, is also available for TR-196 devices.
Multi-Instance Objects Support
This feature introduces support for discovering and updating the CPE parameters associated with multiple object instances, without specifying the actual instance number. The multi-instance object support in the template, adds the flexibility to apply the configuration on selective object instances.
The RDU functionality is also enhanced to instruct the DPE to discover the multi-instance objects for unregistered devices.
The multi-instance object support is available in the following BAC modules:
•
•
•
•
Under Provisioning Group, the property /provGroup/enable/instanceSorting, when set to True, enables you to sort the discovered object instances. This property can be set from the Admin UI and API.
Note
SNMP Traps for Real-Time Device Faults
The fault management module of Cisco BAC facilitates CPEs to raise alarms and send events when any fault occurs. The fault management module can be enhanced to support SNMP trap facility. With the SNMP trap facility, the events received from the CPEs can be converted into SNMP traps and sent to the SNMP manager or Trap receiver.
SNMP Trap for Cisco BAC Process Watchdog and Tomcat
The Cisco BAC process watchdog can be configured to send SNMP traps to the SNMP manager for all the critical conditions of Cisco BAC components. The critical conditions include:
•
•
•
Other Features
This section describes the other new features of Cisco BAC 3.8.
Device Export Does Not Escape New Line Character
This feature introduces support for exporting the device custom properties in a single line output. The custom properties are defined in multiple lines for a device. When you export the device properties using DeviceExport.sh script, the result is saved in .csv format. This script ignores the new line characters and form feed characters such as /r, HTML tags, and so on, to display the output in a single line.
BAC API to Retrieve Property Hierarchy Value
This feature introduces a new getDetails API which retrieves the device properties from all levels in the property hierarchy. If you submit the request using * as input in the getDetails API all the properties from the device property hierarchy are retrieved.
The API client uses the Kiwi script for querying the device property hierarchy, using the immediate and on-connect mode.
Regex Support for BAC Templates
Regular Expression (Regex) provides a conditional way to apply the firmware rules based on the Regex pattern match. Regex pattern is the criteria / range defined for an event. The value of the event returned from the CPE, and the condition specified for the event determine whether the firmware rule is applied to the CPE. The firmware rules are defined in the firmware template with the appropriate event, Regex pattern associated with the event, and the condition for applying the firmware rule.
The following conditions are specified for an event in a firmware rule:
•
•
The Regex support is also available in the configuration templates prerequisites.
IGD Prefix Support
In this release, TR-196 devices support Device or InternetGatewayDevice as the root object.
