Cisco Broadband Access Center 3.8 Administrator Guide
OL-27172-01
Chapter 1 Broadband Access Center Overview
Supported Technology
• Device diagnostics and troubleshooting: You use this feature to focus on a single device and collect
diagnostics information for further analysis. Cisco BAC provides several features to assist
diagnosis:
–
Device history—Provides a detailed history of significant events that occur in a device
provisioning lifecycle.
–
Device faults—Detects devices with recurring faults, which can cause bottlenecks and affect
network performance.
–
Device troubleshooting—Provides detailed records of device interactions with Cisco BAC
servers for a set of devices that are designated for such troubleshooting.
–
Direct device operations—Operations such as IP Ping and Get Live Data can be run on the
device for more insight.
• Multi-instance object 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.
• Scriptable framework: This feature introduces the scriptable extension service which facilitates
running the Java scripts based DPE extensions. This feature also provides the support to load and
unload the extensions dynamically without restarting the DPE.
Supported Technology
This Cisco BAC release supports the provisioning and managing of CPE only through CWMP, outlined
in the TR-069 specification. However, virtually any data models based on TR-069, TR-098, TR-104,
TR-106, TR-181, and TR-196 extensions are supported.
CWMP Technology
TR-069 is a standard for remote management of CPE. This standard defines CWMP, which enables
communication between CPE and an autoconfiguration server (ACS).
CWMP details a mechanism that increases operator efficiency and reduces network management
problems through its primary capabilities. These capabilities include:
• Autoconfiguration
• Firmware Management
• Status and Performance Monitoring
• Device Diagnostics and Troubleshooting
In addition to CWMP, the TR-069 specification defined a version 1.0 of the data model for Internet
Gateway Device (IGD), which has since been expanded by TR-098. CWMP, as defined in TR-069, works
with any data model extended from CWMP, including those defined in TR-098, TR-104, TR-106,
TR-181, and TR-196, upcoming new ones, or those that are vendor specific.
TR-196
TR-196 standard provides the data model for the Femto Access Point (FAP) for remote management
purposes using the TR-069 CWMP.
