Примечания к выпуску для Cisco Cisco IOS Software Release 12.2(4)YA

RJ-45 (10BASE-T Ethernet) hub ports to connect to a local PC or LAN, one Universal Serial Bus (USB) 
port to connect to a local PC, and one RJ-45 console port to connect to a laptop computer/console 
terminal for local Cisco IOS configuration. The Cisco uBR925 router also provides two RJ-11 voice 
ports to connect to FXS telephone devices for VoIP support. The Cisco uBR925 router also provides an
