Broadband and Dial Access Products

Broadband Services Aggregation

Cisco 7200 VXR

When ordered with the Cisco IOS 7200 Series Broadband User Services License (part

number FR-BUS72), the 7200 delivers scaled PPP, RBE, and L2TP sessions and

tunnels in addition to rich IP services. It enables service providers to provision

broadband Internet access and supports all of the popular access technologies deployed

today, including DSL, Cable, Wireless, and Dial Access. It is ideal for medium-density

applications (between 4000 and 8000 Ethernet-bridged, PPPoA, PPPoE in a single

chassis). The 7200 is a modular platform with a choice of processing engines and a

wide variety of WAN and LAN port adapters, including T1/E1, DS3, OC-3, Fast

Ethernet, and Gigabit Ethernet. See http://www.cisco.com/go/7200aggregation and

page 1-28 for more information on the 7200 series.

Cisco 7400 Series

When ordered as a part number 7401ASR-BB, the 7400 series provides

high-performance broadband services aggregation like the 7200, but in a low-power

one rack unit (1 RU) form factor. It offers one port adapter (PA) slot supporting over

40 standard 7200 series PAs, including T1/E1, DS3, OC-3, Fast Ethernet, and Gigabit

Ethernet; making it ideal for small- and medium-density applications. See page 1-34

for more information on the 7400 series.

Cisco 6400 Series Carrier-Class Broadband Aggregator

The Cisco 6400 is designed for use in high-availability environments such as service

provider central offices, and corporate premises; and aggregates access media (DSL,

cable, wireless, and dial) to serve as the intelligent equal access point, allowing

multiple operating companies and service providers access to end users. It includes

switch, router, and line card redundancy.

The Cisco 6400 is a high-performance service gateway that enables the delivery of

network services, VPNs, and voice- and entertainment-driven traffic over any access

media. ATM interfaces connect the Cisco 6400 to dial access servers, DSLAMs, and

Cisco IP DSL Switches; ATM and packet interfaces connect to the network core.

Key Features

• Session scalability and modular design—The Cisco 6400 represents a quantum

leap in session scalability, capable of scaling from 2000 subscribers in its entry

level configuration to 96,000 subscribers in a full configuration.

• Routing and VPN scalability—Using the Cisco 6400, service providers can

simultaneously route end-user traffic over secure, independent pathways

exceeding 1000 different domains or end destinations, with an aggregate

throughput of over 2.4 Gbps forwarding capacity for handling even the most

bandwidth-intensive broadband traffic.
