Fixed Interface Units
The Cisco uBR7100 series universal broadband router contains the following fixed interfaces:
•Ethernet/Fast Ethernet LAN Interface, page
•RF Cable Interface, page
Ethernet/Fast Ethernet LAN Interface
The Cisco uBR7100 series contains a fixed LAN Ethernet/Fast Ethernet autosensing interface with two separately routable
RF Cable Interface
The Cisco uBR7100 series router includes a fixed cable interface card that provides one downstream port and from one to four upstream ports, depending on the model.
On the Cisco uBR7111 and Cisco uBR7114 routers, the cable interface supports the North American DOCSIS channel plan, with a 6 MHz National Television Systems Committee (NTSC) channel width, with a 5 to 42 MHz upstream frequency range. The downstream supports the 54 to 858 MHz frequency range with 64 QAM and 256 QAM data rates, while the upstream supports QPSK and 16 QAM data rates.
On the Cisco uBR7111E and Cisco uBR7114E routers, the cable interface supports the EuroDOCSIS channel plan, with an 8 MHz pulse amplitude modulation (PAM) and SECAM channel width, with a
5 to 65 MHz upstream frequency range. The downstream supports the 54 to 858 MHz frequency range with 64 QAM and 256 QAM data rates, while the upstream supports QPSK and 16 QAM data rates.
Two downstream connectors are provided:
•DS0
•
Note On the Cisco uBR7111E and Cisco uBR7114E routers, the DS0 connector is automatically muted when the DS0 RF port is enabled.
