Cisco uBR7100 Series In Detail

With the Cisco uBR7100 Series, you can quickly

construct an advanced digital broadband cable network

that is well-suited to delivering high-speed Internet access

andotherIP services.Theproductleverages existingcable

TV and telephone lines. The Cisco uBR7100 Series offers:

• Everything needed to build an on-premises

mini-headend—the location that injects broadcast

signals and enables data connectivity to and from

customers. Known in the industry as a Cable Modem

Termination System (CMTS), the Cisco uBR7100 Series

Universal Broadband Router provides complementary

functionality to cable modems.The product includes an

integrated upconverter and modulator that converts

data signals into a form that can be transmitted over a

broadband cable network.

• An embedded network interface that serves as the

high-speed backbone connection; the product comes

with a dual 10/100 BaseT Ethernet network interface

and supports one optional interface such as Ethernet,

FE, serial, high speed serial interface (HSSI), ATM, or

POS.

headend)

• Cisco uBR7114 and Cisco uBR7114E with one

downstream and four upstream ports

The Cisco uBR7111 and Cisco uBR7114 are

CableLabs-qualiﬁed to DOCSIS 1.0 speciﬁcations. The

Cisco uBR7111E and Cisco uBR7114E are

tComLabs-qualiﬁed to EuroDOCSIS 1.0 speciﬁcations.

The product offers a CMTS and router in one box that:

• Provides centralized network intelligence and control

• Uses scarce network bandwidth efﬁciently, including

options to engineer the network based on cable

spectrum characteristics, as well as subscription, type of

service, and desired service levels

• Supports the creation of new pricing models that allow

usage-based billing and quality of service(QoS) options

that guarantee consistent data-access speeds and

improve the online experience to build increased

customer loyalty
