The Cisco uBR7100 series router supports the following Cisco IOS release trains:

• 12.1 EC Release Train and Images
12.2 BC Release Train and Images
The 12.2 BC train is an interim release train that provides DOCSIS 1.1 two-way support, along with
support for selected new features.
Cisco IOS Release 12.2(4)BC1b, provides a migration path from the earlier 12.2 XF releases. Cisco IOS
Release 12.2(4)BC1b supports the Cisco uBR10012 universal broadband router, which provides a
high-capacity, high-throughput cable modem termination system (CMTS), optimized for aggregating traffic
at the edge of the cable network. Designed for cable operators and service providers, the platform connects
residential subscribers via cable modems, digital set-top boxes, or IP telephony cable modems for high-speed
data, broadband entertainment, and IP telephony solutions.
Note Cisco IOS Release 12.2(4)BC1b does not include support for telco-return images.
