Introduction
For information on new features and the Cisco IOS documentation set supported by Cisco IOS Release 12.2(15)BC1, see the "New and Changed Information" section and the "Related Documentation" section.
Cisco uBR7200 Series Universal Broadband Routers
The Cisco uBR7200 series universal broadband routers—the Cisco uBR7223, the Cisco uBR7246, and the Cisco uBR7246VXR—are based on the Data-over-Cable Service Interface Specification (DOCSIS) standards. Each is designed to be installed at a cable operator's headend facility or distribution hub and to function as the cable modem termination system (CMTS) for subscriber-end devices such as the Cisco uBR905 and Cisco uBR925 cable access routers, and other DOCSIS-compliant cable modems (CMs) and set-top boxes (STBs).
Cisco uBR7200 series universal broadband routers allow two-way transmission of digital data and Voice over IP (VoIP) traffic over a hybrid fiber-coaxial (HFC) network. The Cisco uBR7200 series routers support IP routing with a wide variety of protocols and combinations of Ethernet, Fast Ethernet, Gigabit Ethernet, serial, High-Speed Serial Interface (HSSI), Packet over SONET (POS) OC-3 and OC-12c, Asynchronous Transfer Mode (ATM) media, and EtherChannel trunking technology.
Cisco IOS Release 12.2(15)BC1 supports the Cisco uBR7246VXR, Cisco uBR7246, and Cisco uBR7223 universal broadband routers.
Cisco uBR7246VXR Universal Broadband Router
The Cisco uBR7246VXR offers an industry-proven CMTS and carrier-class router in a scalable platform with a high-performance network processing engine to support data, voice, and video services for medium to large network installations.

Early Deployment Releases
These release notes describe the Cisco uBR7200 series universal broadband routers for Cisco IOS Release 12.2(15)BC1. Release 12.2 BC is an early deployment (ED) release based that contains fixes to software caveats as well as support for new Cisco hardware and software features. Feature support is cumulative from release to release, unless otherwise noted.
Supported Features
Cisco IOS Release 12.2(15)BC1 supports the features provided in Cisco IOS Release 12.2 XF, which in turn supported a selected subset of the hardware and software features that were released in Cisco IOS Release 12.0 SC, Cisco IOS Release 12.1 EC, and Cisco IOS Release 12.1(7)CX1 for the Cisco uBR7200 series universal broadband routers.
Table 3 lists the features that were previously supported by the Cisco uBR7200 series in Cisco IOS Release 12.2(4)XF1 and later releases, and any new features that are supported in 12.2(15)BC1.

Unsupported Features
Table 4 lists the features that are not supported in Cisco IOS Release 12.2(15)BC1, along with the most recent, recommended Cisco IOS release that does support that particular feature for the Cisco uBR7200 series routers.
System Requirements
This section describes the system requirements for Cisco Release 12.2(15)BC1 and includes the following sections:
•
•
Memory Recommendations
Table 5 displays the memory recommendations of the Cisco IOS feature sets for the Cisco uBR7200 series universal broadband routers for Cisco IOS Release 12.2(15)BC1. Cisco uBR7200 series routers are only available with a 48 MB or 128 MB of Flash disk memory on the I/O Controller cards. The UBR7200-NPE-G1 uses compact Flash disk only.
Note
The image subset legend for Table 5 is as follows:

Note
Note
System Interoperability
This section clarifies the operation of certain features in the Cisco uBR7200 series universal broadband routers.
•
DOCSIS baseline privacy interface (BPI) gives subscribers data privacy across the RF network, encrypting traffic flows between the CMTS and CM. BPI ensures that a CM, uniquely identified by its Media Access Control (MAC) address, can obtain keying material for services only it is authorized to access.
To enable BPI, choose software at both the CMTS and CM that support the mode of operation. For the Cisco uBR7200 series software, choose an image with "k8" in its file name or BPI in the feature set description.
The CM must also support BPI. CMs must have factory-installed RSA private/public key pairs to support internal algorithms to generate key pairs prior to first BPI establishment. BPI must be enabled using the DOCSIS configuration file.

The Cisco uBR7200 series supports the following DOCSIS 1.0 quality of service (QoS) extensions:
–
–
–
–
–
Note
•
The Cisco uBR7200 series support clock hardware and software to enable high-quality delivery of IP telephony services through synchronized data transmissions. To support the clock feature set, a Cisco uBR7246VXR chassis must be used. The Cisco uBR7246VXR must contain a clock card and either a Cisco uBR-MC16E or Cisco uBR-MC28C cable interface line card. Only these cards support the external clock reference from the clock card to distribute that signal to CMs or STBs attached to the specific network segments.
Each cable modem must also support VoIP applications and the clock reference feature set to enable synchronized timing. The Cisco uBR924 and Cisco uBR925 cable access routers, running Cisco IOS Release 12.0(7)T or later, supports the clock reference feature set automatically.
•
The Cisco uBR7246VXR supports the National Clock Card. The National Clock Card allows the Cisco uBR7246VXR to accept a primary or secondary external clock reference. If there is no primary clock, the Clock Card goes into Holdover. After a period of 2-10 seconds, the Clock Card switches to the secondary clock. When the primary clock is back online, the Clock Card switches to the primary clock after a period of 2-10 seconds. The National Clock Card requires the Cisco uBR-MC1xS or the Cisco uBR-MC1xE cable interface line card.
Supported Hardware
