Preparing for Configuration
Complete these prerequisite steps before you power on and configure the Cisco uBR7100 series router:
Ensure your network supports reliable broadband data transmission. Your plant must be swept,
balanced, and certified based on NTSC or appropriate international cable plant recommendations.
Ensure your plant meets all DOCSIS or EuroDOCSIS downstream and upstream RF requirements.
Ensure your Cisco uBR7100 series router is installed according to the instructions in the hardware
installation guide that came with your CMTS. The chassis must contain at least one port adapter to
provide backbone connectivity, and one Cisco cable modem card to serve as the RF cable TV
interface.
Ensure all other required headend or distribution hub routing and network interface equipment is
installed, configured, and operational (based on the supported services). This includes:
all routers
servers (DHCP, TFTP, and ToD)
network management systems
other configuration or billing systems, depending on your applications, including gatekeepers
and gateways; backbone and other equipment for VPN support; dial-up access servers,
telephone circuits and connections.
other equipment if supporting telco return
