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

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.
