Cisco 1400 Series ADSL Business-Class Router
The Cisco 1400 series ADSL Business-Class routers provides high-speed, always-on connectivity for small- and medium-sized businesses or small branch offices that need to connect seamlessly and securely to the Internet or corporate networks.
The Cisco 1400 series is part of Cisco's comprehensive Digital Subscriber Line (DSL) solutions for business customers, powered by Cisco IOS® software. The Cisco 1400 series offers high-speed Internet/Intranet access with business-class security, high quality of service (QoS), and simple management.
The Cisco 1401 router features a 10BaseT Ethernet interface and an ATM25 interface, which allows connectivity to an Asynchronous Transfer Mode (ATM) cell-based wide-area network (WAN) infrastructure. The ATM25 interface provides an external demarcation point as required by many telcos and can be combined with an external ATM25 asymmetric DSL (ADSL) modem to provide high-speed Internet/intranet access up to 8 Mbps.
Cisco 1401 supports the standard interface and can connect to several different flavors of xDSL modems. This feature enables users to implement Cisco IOS value-added services over legacy ADSL, HDSL, or SDSL modems that feature ATM25 ports.
The Cisco 1417 router features a 10BaseT Ethernet interface and an integrated ADSL DMT Issue 2 ATU-R, with integrated ATM capabilities. The Cisco 1417 can be connected to DSL access multiplexors (DSLAMs) which implement the ANSI ADSL DMT Issue-2 specification, such as the Alcatel DMT Issue 2 DSLAMs.
Cisco 1400 series router delivers important ATM and multiprotocol benefits to small- and medium-sized businesses, including QoS and scalable bandwidth at unprecedented price and performance points. Cisco IOS QoS services allow business customers to implement services and policies that can maximize revenue generated and saved per unit of bandwidth capacity. Traffic classes and prioritization allow a network operator to encourage customers to classify their traffic and then transport the highest value bits during peak usage and heavy congestion periods.
These benefits enable new classes of applications that integrate data, voice, and video. Cisco 1400 series routers are ideally suited for applications such as the following:

The Cisco 1400 series run Cisco IOS software, the unifying thread that differentiates Cisco business-class DSL internetworking solutions from other alternatives in the industry. Its value-added Layer 2 and Layer 3 intelligence enables provisioning of managed DSL services such as VPNs, while maintaining the security and data integrity for the internetwork. And the Cisco IOS software is a flexible vehicle for adding new services, features, and applications to the internetwork. This familiar Cisco IOS command-line interface (CLI) enables service providers and enterprise customers to leverage the experience and training.
The Cisco 1400 series supports the value of end-to-end Cisco network solutions with the following Cisco IOS benefits:
To protect confidential and proprietary information, small businesses must enforce advanced security at the network perimeter---that is at all network boundaries, such as between an internal private LAN and the Internet. Cisco IOS perimeter security technologies provide highly flexible, superior solutions with standard features such as extended access control lists (ACLs) and router/route authentication. Additionally, the optional Cisco IOS Firewall Feature Set provides comprehensive firewall functionality, including context-based access control (CBAC), Java blocking, audit trail, attack detection and prevention, and real-time alerts. Integrating firewall functionality into a multiprotocol router allows a company to leverage an existing router investment and save the training and management costs associated with learning a new platform.
A VPN connects private networks and remote users, using a public network (such as the Internet), while providing services and capabilities equivalent to those offered by private networks built using leased lines. By using the low-cost Internet infrastructure, Internet-based VPNs can significantly reduce WAN costs. However, for VPNs to provide the same benefits as dedicated leased-line networks, they must offer similar levels of security, reliability, and availability. Cisco 1400 series Cisco IOS technologies offer the most complete solutions for these VPN requirements, with features such as:
ATM QoS guarantees with non-real-time variable bit rate (VBR-nrt) and unspecified bit rate (UBR)
The Cisco 1400 series Internet Engineering Task Force (IETF) PPP over ATM feature adds functionality to support Internet service providers (ISPs) and enterprise network providers who can terminate multiple PPP connections (such as in a Cisco 6400). As service providers scale their DSL offerings, they want to provide a secure, scalable connectivity from the local-area network (LAN) to an ISP or corporate network using PPP over ATM and L2TP. By using the PPP over ATM feature, an ISP or enterprise WAN provider benefits from a complete, secure end-to-end solution between the remote branch offices and central-site ATM access concentrator.
With UBR, committed access rate (CAR), and weighted fair queuing (WFQ), you can offer the sub-rate and burstable services and place traffic controls on the access pipe to limit the amount of traffic that can be injected into the network. A network service provider (NSP) can also classify the traffic so that traffic conforming to the access service is labeled as "premium" and excess traffic is "best effort," and both are treated appropriately within the network. Cisco 1400 series routers deliver important ATM + IP QoS features such as:
Cisco IOS Easy IP software enables transparent and dynamic IP address allocation for hosts in remote environments via Dynamic Host Configuration Protocol (DHCP) and minimizes Internet access costs for remote offices. Easy IP reduces router configuration tasks via dynamic PPP/IPCP address negotiation and conserves IP addresses via Network Address Translation (NAT)/Port Address Translation (PAT). Using NAT, Cisco 1400 series routers can translate unregistered or unofficial IP addresses on a remote LAN to a single or multiple registered IP addresses on the router. NAT reduces deployment costs (because it requires only one registered IP address from the ISP) and time (because there is no need to re-address nodes on the unregistered network). This feature also enhances security by hiding the LAN addresses from external view. NAT allows you to define one-to-one address translations as well as many-to-one address translations (known as PAT.)
The Cisco 1400 series router supports a wide range of platforms and applications to monitor and manage company-wide data networks. CiscoView applications, running on Windows 95, Windows NT, and UNIX platforms, provide leadership capabilities in configuration and security management, as well as performance and fault monitoring. The Cisco 1400 series router allows for centralized administration and management via Simple Network Management Protocol (SNMP), via Telnet, or through the console port. CiscoWorks2000, the industry-leading Web-based network management suite from Cisco, simplifies tasks such as network inventory management and device change, rapid software image deployment, and troubleshooting.
Cisco IOS software provides innovative, robust routing intelligence. Cisco IOS software included with Cisco 1400 series routers provides native and seamless connectivity with IP and International Packet Exchange (IPX) routing using RIP, RIPv2, IGRP, Enhanced IGRP, OSPF, BGP, NLSP or RFC 1483 routing protocols. This highly flexible combination of software technologies allows businesses and organizations to choose the right networking technologies for their environment.
Policy-based Cisco IOS features, such as route filtering and routing information translatability, save network resources by preventing data from being unnecessarily broadcast to nodes that do not require it. WFQ, priority output queuing, and custom queuing grant priority to important sessions when network bandwidth is saturated. And Cisco IOS software provides the most scalable solutions available for network applications that require transparent or source-route bridging algorithms.
Cisco 1400 Cisco IOS software has extensive multimedia capabilities that enable companies to support new applications such as streaming video and voice, video on demand, and voice over IP (VoIP) over ATM wide-area infrastructure. In a multicast environment, the video server needs only to transmit a single video stream for each multicast group, regardless of the number of clients viewing it. The video stream is then replicated as required by the Cisco 1401 to allow an arbitrary number of clients to subscribe to the multicast address and receive the broadcast. Cisco IOS features such as the RSVP, CAR, Protocol Independent Multicast (PIM), and WFQ ensure a consistent QoS and high applications availability.
Cisco 1400 routers come with a Quick Start guide with easy-to-follow directions and a color-coded cabling design. For easy deployment, preconfigured software can be stored on a Flash memory PC card (formerly known as a PCM/CIA card) at a central site and then sent to remote sites, where users can simply insert the Flash card into the routers.
