Product Overview

This chapter provides physical and functional overviews of Cisco uBR7100 series universal broadband

routers and contains the following sections that describe router hardware, major components, and

functions of hardware-related features:

• Product Description, page 1-1

• Fixed Interface Units, page 1-6

• Field-Replaceable Units, page 1-7

• Functional Overview, page 1-11

Note Unless otherwise indicated, the term Cisco uBR7100 series in this manual refers to all models of the

Cisco uBR7100 series universal broadband router, including the Cisco uBR7111, Cisco uBR7111E,

Cisco uBR7114, and Cisco uBR7114E routers.

Product Description

The Cisco uBR7100 series universal broadband router is a cable modem termination system (CMTS)

that provides Internet, local area network (LAN), and wide area network (WAN) access for cable

modems and set-top boxes (STBs) over a coaxial cable connection. The router enables high-speed data

services to be packaged similar to basic cable television service or video programming.

The Cisco uBR7100 series routers support two-way data and digitized voice connectivity over a

bidirectional cable television and IP backbone network, using one of the following two standards:

• The Cisco uBR7111 and Cisco uBR7114 support the Data-over-Cable Service Interface

Specifications (DOCSIS)—DOCSIS 1.0 and DOCSIS 1.1. DOCSIS supports the 6 MHz North

American channel plans using the ITU J.83 Annex B RF standard. The downstream uses a 6 MHz

channel width in the 85 to 860 MHz frequency range, and the upstream supports the 5 to 42 MHz

frequency range.

• The Cisco uBR7111E and Cisco uBR7114E support the European Data-over-Cable Service

Interface Specifications (EuroDOCSIS)—EuroDOCSIS 1.0 and EuroDOCSIS 1.1. EuroDOCSIS

supports the 8 MHz Phase Alternating Line (PAL) and Systeme Electronique Couleur Avec

Memoire (SECAM) channel plans using the ITU J.112 Annex A RF standard. The downstream uses

an 8 MHz channel width in the 85 to 860 MHz frequency range, and the upstream supports multiple

channel widths in the 5 to 65 MHz frequency range.
