Cisco 2600 Series — Routers

Product Overview

Cisco Systems extends enterprise-class versatility, integration and power to branch offices with the Cisco 2600 series router family, for an attractive price.

The Cisco 2600 series modular architecture offers network managers and service providers a branch office solution that provides the versatility needed to adapt to changes in network technology, as new services and applications become available. With full support of the Cisco IOS software, Cisco 2600 modular architecture provides the power to support the advanced Quality of Service (QoS), security, and network integration features required in today`s evolving enterprise and service provider networks.

The Cisco 2600 series shares modular interfaces with the Cisco 1600, 1700 and 3600 series, providing a cost-effective solution to meet today`s branch office needs for applications such as:

• Secure Internet/intranet access with Firewall protection

• Multiservice voice/data integration

• Analog and digital dial access services

• Virtual Private Network (VPN) access

• Inter-VLAN routing

• Routing with Bandwidth Management

While the pace of change in network technology continues to increase, global deregulation of telecommunications has allowed more service providers to compete for data, voice and video network services. Only companies who have designed their network infrastructures with these factors in mind will be able to benefit from the lower prices caused by increased competition and protect themselves from "technology lockout" in the future.

The Cisco 2600 series features single or dual fixed LAN interfaces, a network module slot, two Cisco WAN interface card (WIC) slots, and a new Advanced Integration Module (AIM) slot. LAN support includes single and dual Ethernet options; 10/100 Mbps autosensing Ethernet; mixed Token-Ring and Ethernet; and single Token Ring chassis versions. WAN interface cards support a variety of serial, ISDN BRI, and integrated CSU/DSU options for primary and backup WAN connectivity, while available network modules support multiservice voice/data/fax integration, departmental dial concentration, and high-density serial options. The AIM slot supports integration of advanced services such as hardware-assisted data compression and in the future, encryption. All Cisco 2600 series routers include an auxiliary port supporting 115Kbps Dial On Demand Routing, ideal for back-up WAN connectivity.

As part of Cisco`s comprehensive end-to-end networking solution, the Cisco 2600 series allows businesses to extend a cost-effective, seamless multiservice network infrastructure to the branch office. By deploying the Cisco 2600 series router, companies can consolidate the functions of multiple separate devices into a single, compact package that can be managed remotely. Because the Cisco 2600 series is modular, interface configurations are easily customized to accommodate a wide variety of network applications. Some of these applications include the following:

• Multiservice Voice/Data/Fax Integration

  The Cisco 2600 Series reinforces Cisco`s commitment to provide multiservice voice/data integration capabilities across its product portfolio, allowing network managers to save on long-distance inter-office toll charges and enabling next-generation voice-enabled applications such as integrated messaging and Web-based call centers. Using the sophisticated QoS features of Cisco IOS software, such as the Resource Reservation Protocol (RSVP), Weighted Fair Queuing (WFQ), FRF.11 and FRF.12, and IP Precedence, the Cisco 2600 series allows voice traffic to be digitized, encapsulated in data packets or Frames, and prioritized over other data traffic for a highly efficient, end-to-end network infrastructure for Voice over Frame Relay or Voice over IP.

• Analog and Digital Dial Services

  With support for up to 36 high-speed asynchronous ports or up to 64 ISDN B channels, the Cisco 2600 provides a cost-effective, single-box dial concentration solution for enterprise or service provider networks. By allowing users in remote locations to call a local phone number for access to both the corporate LAN or the Internet, enterprises can reduce toll charges. For example, the Cisco 2600 series provides dial-up capability for up to 32 remote users, accommodating protocols such as PPP, SLIP, ARA, and Xremote on any port, while supporting dedicated connections to the Internet and the corporate intranet. The new integrated 8 and 16 analog modem modules provide for a single box Remote Access Server solution with improved manageability.

• Virtual Private Network (VPN) Access and Firewall Protection

  Many companies have begun to use Virtual Private networks (VPNs) to reduce WAN costs by deploying secure tunneled connections via the Internet. VPNs can be rapidly set up and torn down to provide extranet links to customers, business partners and remote employees. With extra performance required to support advanced Cisco IOS security features such as IPSec and 3DES encryption, the Cisco 2600 series can support multiple encrypted tunnels and provide the advanced security features of the Cisco IOS Firewall feature set.

  For example, a Cisco 2610 router in the branch office can provide secure privileged access to business partners while also supporting another connection to a Cisco 2621 in the main office. The dual-LAN architecture of the Cisco 2621 allows the customer to create an external subnet or "DMZ" for a public Web server outside the firewall while providing security for the internal network. Simultaneously, remote users can connect to local point of presence Cisco 5300 which tunnels across the Internet to the same 2621 saving on long distance or "1-800" connection charges. Cisco IOS features such as tunneling, data encryption, and termination of Remote Access WANs via IPSec, Layer 2 Forwarding (L2F) and Layer 2 Tunneling Protocols (L2TP) make the Cisco 2600 an ideal platform for building virtual private networks or outsourced dial solutions.

• Serial Device Concentration

  The Cisco 2600 provides a cost-effective, flexible solution for concentrating serial devices in remote locations. Async/sync ports provide connections to serial devices such as SDLC concentration devices, alarm systems, ATMs, debit/credit terminals and cash registers. With full Cisco IOS protocol support including SDLC, BSC, BTSUN, STUN, X.25, Frame Relay, and polled async, the Cisco 2600 consolidates traffic from a wide variety of serial devices over a single connection, eliminating costly dial-up BSC links.

  The 4- or 8-port asynchronous/synchronous network modules can be combined with, for example, the mixed Ethernet/Token Ring Cisco 2612 and integrated CSU/DSU and BRI WICs to address various retail or financial branch office environments. Stacking the Cisco 2600 series with Cisco LAN switches such as the Catalyst 1900, 2820 and 2900XL series enables network administrators to manage remote branch office environments efficiently using CiscoWorks and CiscoView network management solutions.

• Mixed WAN services

  Cisco 2600 offers a variety of connectivity options with the reliability and high performance required to address today`s evolving branch office WANs. Up to 8 dedicated 128-kbps synchronous connections, one ISDN BRI and one T1/fractional T1 Frame Relay connections can be simultaneously supported with a single Cisco 2600.

• LAN-to-LAN services

  The Cisco 2600 offers a unique combination of versatility, integration and power at an attractive price for branch office LAN-to-LAN routing applications. Many of today`s multiple device solutions gateways can be integrated into one Cisco 2600 configuration. Cisco 2600`s RISC-based processor provides the power needed for the dynamic requirements of the remote branch office, achieving wire speed Ethernet to Ethernet routing with up to 25 thousand packets per second (Kpps) throughput capacity.

• Evolving Business Applications

  The Cisco 2600`s combination of fixed LAN port(s) along with modular interfaces provide customers with the ability to change or meet future networking requirements without a "forklift upgrade."

Memory, Power Supply and Cable Options for the 2600 Series Routers

Memory

The Cisco 2600 series uses two types of replaceable or upgradeable memory: DRAM and Flash. DRAM memory is implemented with up to two DIMMs in any combination of sizes. Flash memory is implemented with a single SIMM. The Cisco 2600 series ships standard with 24MB of DRAM memory; the first socket contains a 16 MB DRAM DIMM; the second socket contains an 8 MB DRAM DIMM. You can upgrade DRAM to a maximum of 64 MB: 32 MB in each socket. The Cisco 2600 series router ships standard with 8 MB of Flash, expandable to 16 MB of Flash supported by a single socket.

The Cisco 2600 series routers use a DRAM memory configuration that is different from other Cisco routers. Unlike the Cisco 4000 series routers, for example, which have separate physical locations for processor memory and packet memory, the Cisco 2600 series routers use one pool of DRAM memory. The DRAM is partitioned into processor memory and packet memory areas. For example, the memory of a 16 MB DRAM configuration is split into 12 MB for processor memory and 4 MB for the packet memory.

The Cisco 2600 allows you to load new system images via the LAN from a TFTP server. You can also load images from a local or remote PC through the console or auxiliary ports using the Xmodem or Ymodem protocols.

Redundant Power Supply

The RPS adapter option is available for the Cisco 2600 series as a spare (ACS-2600RPS=) or as part of a factory configured chassis (Cisco26xx-RPS). The RPS adapter takes the place of the power supply and must be used with the PWR-600 RPS unit, connected via the associated RPS power cable. For more details, please refer to the PWR-600 section in this catalog.

DC Power Supply

A single-feed DC power supply option is available for the Cisco 2600 series as a spare (PWR-2600-DC=) or as part of a factory configured chassis, (Cisco26xx-DC).

NEBS Level 3 / ETSI Kit

A NEBS level 3 / ETSI kit ensures a Cisco 2600 router meets NEBS level 3 / ETSI standards for networking equipment, usually found in central office environments. This kit includes: the 23 in. Hendry bay/24 in. rack mounts, the ground lug kit, shielded LAN cables, bezel replacement label (for depth reduction in Central Office rack environments) and related documentation. This kit is available for the Cisco 2600 series as a spare (ACS-2600NEBS/ETSI=).
