Overview
Cisco 7400 Series Internet Router
A Quick Look
The Cisco 7400 Series Internet Router is one of the industry's leading Internet routers available in a compact form factor—one_rack unit (RU). The high performance, exceptional flexibility, and versatility found in the Cisco 7400 ideally positions this router for applications such as broadband subscriber aggregation, managed services customer premises equipment (CPE), and network services gateway.
Key Benefits
•
"Pay-as-you-grow" granularity with small, stackable form factor
•Highest service density and performance per 1RU in the industry
•High level of flexibility and versatility with support for over 40 modular interfaces, including serial, Channelized, ISDN, Frame Relay, ATM, IP, and 64K to OC-3
•Support up to 320,000 subscribers per 7-foot rack

Broadband Subscriber Aggregation (Cisco 7401 ASR-BB)
The Cisco 7400 can aggregate thousands of broadband subscribers to enable value-added IP services. In service-provider networks, it can accept a large concentration of broadband subscriber traffic from a variety of devices such as DSL access multiplexers (DSLAMs), cable modem termination systems (CMTSs), and wireless concentrators. The Cisco 7400 can also efficiently terminate IDSN Primary Rate Interface (PRI) and BRI traffic, making it an ideal modular approach to building an ISDN DSL (IDSL) or ISDN infrastructure. When deployed by carriers and cable operators in regional data networks, the Cisco 7400 enables cost-effective, highly scalable, secure wholesale access for creating and deploying value-added IP services. Software features for Cisco 7400 broadband aggregation include:
•PPP over ATM, PPP over Ethernet, and PPP over VLAN
•RBE for RFC 1483 or RFC 1490-based permanent-virtual-circuit (PVC) terminations
•Virtual routing for high-density circuit termination with increased security, flexibility, and scalability
•Password Authentication Protocol/Challenge Handshake Authentication Protocol (PAP/CHAP) and Remote Access Dial-In User Service (RADIUS) authentication
•Intelligent L2TP tunneling support
•Differentiated, value-added services with hardware-accelerated PXF services along with flexible modular interfaces for traffic aggregation, including OC-3, DS3, Fast Ethernet and Gigabit Ethernet, POS, and more
•Ideal for small- and medium-density aggregation for network operators, competitive local exchange carriers (CLECs), and Internet service providers (ISPs)
•MPLS VPN and full L2TP-to-MPLS support
Managed Services CPE (Cisco 7401 ASR-CP)
The Cisco 7400 is an ideal platform for managed services where end customers are given their own router, and the service provider manages it for them. In many cases, stacks of routers are needed. In such environments, space, airflow, and heat/power dissipation are issues. The Cisco 7400 delivers the performance of the Cisco 7200 in one-third the space, with one-fifth the power and with front-to-back airflow.
Following is the list of PXF-accelerated managed services CPE features for the Cisco 7400:
•ATM, Frame Relay, Dynamic Packet Transport (DPT), POS, Channelized, and serial interfaces from 64K to OC-12
•Full range of traditional Cisco routing protocols, including Routing Information Protocol (RIP), Border Gateway Protocol (BGP), Open Shortest Path First (OSPF), and MPLS
•Virtual routing for high-density circuit termination with increased security, flexibility, and scalability
•Ideal for small and medium-density aggregation for network operators, CLECs, and ISPs
•MPLS VPN and full L2TP-to-MPLS support
•Stackability (50 watts, front-to-back airflow)
•Differentiated, value-added services with hardware-accelerated PXF services along with flexible modular interfaces for traffic aggregation, including OC-3, DS3, Fast Ethernet and Gigabit Ethernet, POS, and more
Network Services Gateway (Cisco 7401 ASR-CP)
Cisco IOS VPN services (including tunneling features Layer 2 Forwarding [L2F], L2TP, and generic routing encapsulation [GRE] tunneling) combined with security features, high-speed processing power, and unparalleled connectivity options make the Cisco 7400 an ideal choice for services gateway applications. Enterprises and ISPs use the Cisco 7400 as the preferred gateway for a wide variety of applications.
The following is a list of PXF-accelerated services supported for the network services gateway on the Cisco 7400:
•Network Address Translation (NAT)
•Access control list (ACL)
•NetFlow accounting and export
•Low-latency queuing (LLQ)
•Class-Based Weighted Fair Queuing (CBWFQ)
•Class-Based Weighted RED (CBWRED)
•Committed access rate (CAR)
