The Cisco 3600 is the industry's first true multifunction platform with the versatility to support branch/enterprise hybrid dial access applications, LAN-to-LAN or routing applications, and multiservice applications in a single platform. It provides unprecedented modularity options with a broad range of available network modules, enormous flexibility with a variety of configurable options for customer-specific application scenarios, and, above all, high-performance to support any of these applications.
The Cisco 3640/3640A server is equipped with four network module slots, and the Cisco 3620 has two network module slots. Dial connectivity is supported with a series of network modules offering Integrated Services Digital Network (ISDN), Primary Rate Interface (PRI), ISDN Basic Rate Interface (BRI), integrated digital and analog modems, very high density asynchronous interfaces, two and four port Voice/Fax, 25-Mbps ATM, low-speed asynchronous/synchronous serial, and hardware compression assisted network modules. LAN and WAN connectivity are provided by a series of mixed-media cards supporting Ethernet, Token Ring, and a variety of WAN technologies. Routing applications are supported with high-density Ethernet and a single-port, autosensing, Fast Ethernet network module. Voice and Fax multiservice applications are also supported with integrated voice network modules and voice interface cards.
The Cisco 3600 is an ideal upgrade to branches that have outgrown their current routing hardware and require the next generation of hardware for their "power branch" applications. The flexibility of the Cisco 3600 Series enables you to support a variety of solutions for the power branch office environment. No matter how much your requirements may vary from place to place, the Cisco 3600 platform has the performance and diversity to meet your needs at a very costeffective price. For instance, a branch office using ISDN to connect to the main office may require dedicated Frame Relay service in a year's time with increased traffic on the network—without a forklift upgrade in the wiring closet. As a multifunction solution, you can rely upon the outstanding performance, reliability, security, and flexibility of the Cisco 3600 platform to meet your needs for many years. Multiple devices become quite expensive to manage, configure, and support when compared to a single, multifunction device with integrated management, configuration, and single vendor support.
Finally, Cisco IOS® software contains many features that provide security, reliability, and WAN optimization. In any application, the Cisco IOS features can be used to control ongoingWANcosts. For example, the Cisco 3600 server supports dial-on-demand routing (DDR) and dial backup, as well as protocol spoofing and snapshot routing to reduce unnecessary WAN traffic. To further reduce WAN costs and increase effective bandwidth, Cisco IOS software supports data compression over Frame Relay, dedicated leased line, and dial networks. Cisco IOS software has extensive multimedia capabilities that enable companies to support new applications such as teleconferencing over the WAN. Features such as the Resource Reservation Protocol (RSVP), Protocol Independent Multicast (PIM), generic traffic shaping, Committed Access Rate (CAR), custom and priority queuing, and Weighted Fair Queuing (WFQ) ensure a consistent quality of service and high applications availability.
Multifunction Capabilities of the Cisco 3600 for the Power Branch
The Cisco 3600 is targeted at meeting the evolving requirements of the power branch. A power branch can be defined as one that has outgrown its initial networking hardware, and needs to add functionality such as high-density dial access server support, multiservice integration of voice and fax, advanced Quality of Service (QoS), security, ATM and, at the same time, provide an open architecture for future requirements such as Digital Subscriber Line (DSL), video, and advanced voice features. The Cisco 3600 has the performance built-in to handle these diverse needs, and also has power to address the future branch requirements, in a modular chassis with network module options that provide the ultimate investment protection.
For example, as an ISDN access solution, a Cisco 3600 ISDN PRI access server with integrated digital modems is ideal for branch offices with limited rack space. Customers or telecommuters save line costs by dialing a local access number, and then are routed to services over the WAN. A backup T1 serial connection using a mixed-media LAN module with T1 WAN interface cards also provides LAN access. Up to 60 digital modems may be installed in a Cisco 3640/3640A chassis to simplify management, conserve rack space, and ensure interoperability with the rest of your Cisco network.
As a remote distributed access server, the Cisco 3600 is optimal for deploying in a dispersed dial infrastructure. For example, geographic concerns require a service provider to deploy a large number of small points of presence (POPs) that are geographically dispersed. The Cisco 3600 with its redundant high-speed serial ports provides for backhaul of data to points of aggregation, while its redundant LAN interfaces, including the ability to provide Fast Ethernet and Token Ring, provide the maximum flexibility of deployment in a variety of LAN environments.
Cisco 3600 Provides Multiprotocol Dial Access into Enterprises
Increasingly, enterprises and branch offices are experiencing the need to extend network access to a broad range of remote users, including employees, vendors, customers, and partners. Successful remote access means being able to connect these users from practically any location with support for any protocol, almost transparently. Varying demands of telecommuters and mobile users necessitate both ISDN and async connections. Today, users expect to get the same access and quality of service they receive when connected locally. To meet this requirement, the remote access server must be part of the total network solution and scale with it to meet the growing remote access needs.
The Cisco 3600 supports the most complete set of access protocols of any access server in the industry, including, Point-to-Point Protocol (PPP), and Multilink PPP (MP), integrated analog and digital modems, 56 Kbps/V.90, dial-out and fax-out, Modem over BRI, R2, and CAS signaling. The flexible configuration options of the Cisco 3600, when combined with the power of the Cisco IOS software, meet the requirements for secure, reliable, dial-in connections with rich software support of this critical multiprotocol, dial access application.
Features
Full Power of Cisco IOS Software
The Cisco 3600 is a component of the Cisco complete end-to-end solution set for dial connectivity. No other vendor can offer remote users as many options for Internet access and enterprise extension. This offering is also boosted considerably by the ability of the Cisco IOS software to affordably deploy dial virtual private networks (Dial VPNs). Users can also save through bandwidth optimization techniques such as data compression and can deploy high-quality network security firewalls and data encryption.
Security
The primary concern for most network managers today is security. The Cisco 3600, along with the popular and robust Cisco IOS software, provides comprehensive security throughout customer core networks. For remote user environments, the Cisco 3600 extends that proven core security to mixed-media dial-in sites. Among the security features supported by the Cisco IOS software are, IOS Firewall Features, DES, and 3DES data encryption, extended access lists, violation logging, Remote Access Dial-In User Service (RADIUS), Kerberos V, and TACACS+ with authentication, authorization, and accounting (AAA).
Management
The Cisco 3600 offers a complete graphical user interface (GUI) management tool called CiscoWorks and CiscoWorks 2000, providing for graphical configuration, monitoring, and debugging of the Cisco 3600 chassis and its associated network modules. The Cisco configuration management capabilities provide network managers with complete control over network statistics and the ability to configure and tune network operations from a central location. Comprehensive debugging tools are available in Cisco IOS software to substantially reduce the time and cost associated with problem isolation and recovery.
To address the internal modems available in the Cisco 3600, an optional, advanced, modem management feature set is available, which provides extensive bandwidth optimization features to help branch and enterprise customers lower the recurring costs associated with operating a geographically dispersed wide-area network.
The modem management feature set includes call-inprogress monitoring, hard and soft busy out, grouping, a user-defined threshold for alarms, and statistics. Administrators can view real-time information (for current or previous calls) such as modem modulation scheme, modem protocol, modem EIA/TIA-232 signal states, modem transmit and receive rates, and analog signal-to-noise ratio. The modems can be managed via the same tools used to manage the rest of the network, providing network managers with one solution at a central management point.
Scalability
The Cisco implementation of the Multichassis Multilink Point-to-Point Protocol (MMP) allows customers to start small and scale additional access servers as required, while still being able to dial into one center. Enterprise and branch office network managers with medium dial-in pools can easily scale and integrate their access infrastructures to aggregate multiple calls on multiple servers, providing a higher-bandwidth solution to their end users. These scalability features are critical for service providers and enterprise customers as they build resilient systems that leverage distributed network reliability. Multilink Point-to-Point-Protocol (MP) allows users to take advantage of ISDN connections and achieve a raw 128-kbps data throughput using two B channels. Async users can also take advantage of this feature, if supported on their workstation, with two modems connected over two phone lines.
MMP support is a key factor in scaling the Cisco 3600 solution to meet expanding user requirements. MMP allows calls to be "linked," regardless of the physical chassis each call is placed to, allowing Cisco 3600 chassis to be stacked and viewed as one dial-in pool.
