Key Features and Benefits:

The Cisco 2600 Series supports a wide range of performance and scalability for branch-office networking solutions, allowing businesses to extend a cost-effective, transparent network infrastructure to the branch office with the following benefits:


• Investment protection-Support for field-upgradable, modular components on the Cisco 2600 Series allows customers to easily change network interfaces without a complete system upgrade of the entire branch-office network. The AIM slot(s) further protects investments by offering the expandability to support advanced services such as hardware-assisted data compression, data encryption, ATM data and voice access, or DSP digital voice applications.

• Lower cost of ownership-By integrating the functions of switches, channel service units (CSUs), data service units (DSUs), ISDN Network Termination 1 (NT1) devices, firewalls, modems, compression or encryption devices, and other equipment found in branch-office wiring closets in a single, compact unit, the Cisco 2600 Series provides a space-saving solution that is more manageable.

• Integrated flexible routing and low-density switching-With support of an optional 16-port 10/100 Cisco EtherSwitch® Network Module, branch offices can take advantage of the flexibility of integrated routing and switching functions in one unit for low port densities. This offers high-speed connections between individual desktops, servers, and other network resources in a single unit for Layer 2 and allows WAN connection at Layer 3 through the router. An optional external power chassis provides in-line power to IP phones and to Cisco Aironet® 802.11 base stations.

• Integration of content networking and branch-office routing-With the integration of an optional content-engine network module with branch-office routing, Cisco offers the industry's first and only router-integrated content-delivery system. Combining intelligent caching, content routing, and management with robust branch-office routing, WAN bandwidth is conserved for important branch IP services such as voice over IP (VoIP), while simplifying configuration, deployment, and operations.

• Voice and data integration-Cisco offers the industry's broadest, most scalable multiservice voice and data integration solution set. The Cisco 2600 Series allows network managers to provide scalable analog and digital telephony without investing in a one-time solution, giving enterprises greater control of their converged telephony needs. Using the voice and fax modules, the Cisco 2600 Series may be deployed in both VoIP and voice-over-Frame Relay (VoFR) networks. The packet voice trunk network module supports up to 60 simultaneous voice calls as well as supporting routing and other services. When used with the ATM AIM, voice over ATM (VoATM) using ATM Adaption Layer 2 (AAL2) or AAL5 can be deployed.

• Enterprise and provider-class solution-This solution meets the requirements of multiservice enterprises and their managed service customer-premises-equipment (CPE) providers with high-reliability features, multiple WAN connections, and the ability to migrate from data-only to time-division multiplexing (TDM) voice and from data to packetized voice and data infrastructure.

• Security-With the integration of optional VPN modules, Cisco IOS Software-based firewalls and Intrusion Prevention System (IPS), content-engine network modules, or intrusion detection network modules, Cisco offers the industry's most robust and adaptable security solution for branch-office routers. VPN modules can be used to provide up to 10 times the performance over software-only encryption. Additionally, the new Cisco Intrusion Detection System Network Module allows decryption, tunnel termination, and traffic inspection at the first point of entry into the network while freeing the router CPU from process-intensive IDS tasks.

• Business-class DSL connectivity-With the WIC-ADSL, WIC-1ADSL-I-DG, WIC-1ADSL-DG, WIC-1SHDSL, and WIC-1SHDSL-V2 modules added to the Cisco 2600 Series offers a broad range of business-class broadband options with scalable performance, flexibility, and security for branch and regional offices. The Cisco 2600 Series provides an ideal solution for a variety of businesses requiring high-speed business-class DSL connectivity on a secure, high-performance modular platform.

This new 128-MB DIMM offers higher-density memory, providing the ability to support memory increases to 256 MB of DRAM (with the correct ROMmon).


Cisco 2600 Series Hardware and Software Options:

Cisco 2600 Series routers offer a choice of Ethernet, Token Ring, and autosensing 10/100 Ethernet LAN interfaces. In addition, depending on the model, one network module slot, two or three WIC slots, and one or two AIM slots as well as one 115.2-kbps console port and one 115.2-kbps auxiliary asynchronous port are offered.


Network Module Options:

Network modules help enable the Cisco 2600 Series to be customized to meet the needs of virtually any branch office. These modules support a broad range of applications, including multiservice voice and data integration, analog and ISDN dial access, ATM access, integration of low-density switching, IDSs, content networking, and serial device concentration (refer to Table 5 for the complete list of supported network modules for the Cisco 2600 Series). Other advantages of the network module are to provide integrated services onto one platform for greater management of services and ease of operations. By offering network modules such as the Cisco EtherSwitch Network Module, content engine, network analysis, and intrusion detection network modules, more services are integrated onto a single platform. These modules provide the advantage of integrating switching, content networking, or intrusion detection with routing onto one platform for greater management and ease of operation. The Cisco 16-Port 10/100 EtherSwitch Network Module combines robust Layer 3 flexible WAN routing with low-density line-rate Layer 2 switching, providing straightforward configuration, easy deployment, and integrated management in a single platform. The Cisco EtherSwitch modules use the powerful features available in both Cisco IOS Software and Cisco Catalyst switching, with hardware supporting 802.1p Layer 2 prioritization, while Cisco IOS Software supports Layer 3 Differentiated Services (DiffServ) and class-of-service (CoS) markings for critical business data.


Multiflex Voice/WAN Interface Card and WIC Options:

The Cisco 2600 Series WIC slots supports 20 interface cards with the introduction of the 1-port xDSL and 1- or 2-port analog modem WICs. The Cisco 2600 Series of modular routers support both asymmetric DSL (ADSL) and the G.shdsl WICs. These offerings bring high-speed business-class broadband service to the award-winning Cisco 2600 Series of multiservice routers. Now small and medium-sized businesses (SMBs), enterprise branch offices, and service provider-managed service users can take advantage of a highly flexible and scalable solution for data-only or voice and data integration, with secure VPN options. The single- and dual-port multiflex voice/WAN interface cards (VWICs) combine WIC and VIC functions to provide unparalleled flexibility, versatility, and investment protection. Supporting up to T1 and E1 rates with integrated T1 CSUs and DSUs or E1 DSUs, the multiflex VWICs can be used in data-only, channelized (drop and insert) voice and data integration applications, as well as packet voice and data connections to a PBX or the Public Switched Telephone Network (PSTN). (Packet voice requires the use of the high-density voice trunk network module.) Unlike traditional multibox voice and data components, when used in a Cisco 2600 or Cisco 3700, the T1/E1 multiflex VWICs deliver a single-box voice and data platform that provides a graceful migration from data only to channelized voice and data, to packet voice and data.
