Cisco Cisco IOS Software Release 12.2(8)YJ

These release notes describe the following topics:

The DOCSIS-based Cisco uBR905 and Cisco uBR925 cable access routers give small office, home 
office (SOHO) and branch office subscribers high-speed Internet or intranet access.The Cisco uBR905 
and Cisco uBR925 cable access routers act as cable modems to connect computers and other customer 
premises devices at a subscriber site to the service provider cable, hybrid fiber-coaxial (HFC), and IP 
backbone network.

The Cisco uBR905 cable access router supports data traffic via a shared two-way cable system and IP 
backbone network. The Cisco uBR925 cable access router supports both data and Voice over IP (VoIP) 
traffic via a shared two-way cable system and IP backbone network. 

Both cable access router models support four Ethernet hub ports to connect to PCs and other customer 
premises equipment (CPE) devices. The Cisco uBR925 cable access router also supports connecting one 
PC or CPE device through a Universal Serial Bus (USB) port. 

The Cisco uBR905 and Cisco uBR925 cable access routers are based on Data-over-Cable Service 
Interface Specifications (DOCSIS) and interoperates with any bidirectional, DOCSIS-qualified cable 
modem termination system (CMTS). These cable access routers ship from the Cisco factory with a 
Cisco IOS software image stored in nonvolatile Flash memory that supports DOCSIS-compliant 
bridging data operations. 

In previous Cisco IOS releases, the Cisco uBR905 and Cisco uBR925 cable access routers used the same 
software images. In Cisco IOS Release 12.2(8)YJ, however, the Cisco uBR905 cable access router must 
use the non-voice image (ubr925-k9o3sy5-mz) due to memory requirements.
