12.3 BC Release Train Images and Requirements

The Cisco 12.3 BC release train is the latest Cisco IOS release train to support the Cisco uBR7200
Series, and emphasizes additional features and performance specifically for the Cisco uBR7246VXR
universal broadband router.
Table 1-2
Cisco uBR7200 series universal broadband routers for Cisco IOS Release 12.3(9a)BC.
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.
Flash disks, an alternative to linear Flash memory, are Flash memory-based devices that can be used as
Note
file storage media in the PCMCIA card slots of the I/O Controllers. Each I/O Controller has two
PCMCIA slots and can be configured with up to 256 MB of Flash disk memory.

A Cisco uBR7200 series router requires 256 MB of DRAM memory on the NPE processor card when
Note
HCCP redundancy is configured and the router is supporting more than 3,000 cable modems. Using less
memory in these conditions results in temporary out-of-memory situations and incomplete
synchronization between the Working and Protect interfaces.
