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.”
Key Features and Benefits
As part of Cisco`s comprehensive end-to-end networking solution, the Cisco 2600 series supports the value of end-to-end Cisco network solutions with the following benefits:
? Multiservice integration
Allows network managers to save long-distance inter-office toll charges and enable next-generation voice applications such as integrated messaging and Web-based call centers.
? Investment protection
Because the Cisco 2600 series supports field-upgradable modular components, customers can easily change network interfaces without a “forklift upgrade” of the entire branch office solution. The AIM slot of the Cisco 2600 platform further protects investments by enabling new services such as hardware-assisted data compression and, in the future, hardware-assisted data encryption without using an external interface slot.
? Reliability
To maximize network uptime, the Cisco 2600 series offers a redundant power supply (RPS), which can be shared with other Cisco products. The Cisco 2600 series also supports Cisco IOS reliability features such as dial-on- demand routing (DDR) to restore both data and voice services automatically in the event of a primary link failure.
? Lower cost of ownership
Integrating the functions of CSU/DSUs, ISDN Network Termination (NTI) devices, modems, firewall, compression and encryption devices and other equipment found in branch office wiring closets in a single, compact unit provides a space-saving solution that can be managed remotely using network management applications such as CiscoWorks and CiscoView.
? Part of a Cisco end-to-end solution
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.
Standard Features
The Cisco 2600 series is available in the following six base configurations:
? Cisco 2610: One Ethernet port
? Cisco 2611: Two Ethernet ports
? Cisco 2612: One Ethernet port and One Token Ring port
? Cisco 2613: One Token Ring port
? Cisco 2620: One 10/100 Mbps auto-sensing Ethernet Port
? Cisco 2621: Two 10/100 Mbps auto-sensing Ethernet Ports
Each model also has two WAN interface card slots, one network module slot, and one AIM slot. All Cisco 2600s include the Cisco IOS IP feature set; other feature sets may be selected as upgrade options.

Key Features and Benefits
Cisco 1003 and Cisco 1004 ISDN Routers
The Cisco 1003 and Cisco 1004 routers are small, desktop routers that connect small, remote sites with Ethernet LANs to ISDN WANs.
The main difference between the two routers is that the Cisco 1004 router includes an integrated network termination 1 (NT1) device and the Cisco 1003 router does not. The ISDN service provider supplies the NT1 connection worldwide, except in North America, where the NT1 device is supplied by the customer. Therefore, the Cisco 1004 router is for use in North America, and the Cisco 1003 router is applicable worldwide.
The rear view of the routers looks the same except for the following differences, shown in the following figure:
? The BRI port on the Cisco 1003 is labeled “ISDN S/T,” and “Cisco 1003″ is stamped on the upper left corner of the chassis (not illustrated).
? The BRI port on the Cisco 1004 is labeled “ISDN U,” and “Cisco 1004″ is stamped on the upper left corner of the chassis (not illustrated).
The Cisco 1003 and Cisco 1004 routers include the following standard features:
? One Ethernet 10BaseT port with an RJ-45 connector
? One ISDN BRI port with an RJ-45 connector (the Cisco 1004 router includes an integrated NT1 device)
? One console port with an RJ-45 connector
? Console cable kit and power supply
? One external PCMCIA slot for optional Type-2 Flash memory card
? Software booting over an Ethernet LAN using TFTP
? Optional Flash memory card to store software image and configuration files, allowing network-independent booting and software updates over the WAN or LAN connections
? LAN-to-LAN DDR routing over ISDN lines
? IP, IPX and AppleTalk routing
? Transparent bridging
? IPX and SPX spoofing
? PPP compression and bandwidth-on-demand with load balancing for throughput up to 512 kbps
? HDLC and standards-based PPP
? Increased security with CHAP, PAP, packet filters, local password and CLI/ANI
? Network management and monitoring through the console port or over the network using SNMP or Telnet
? Support for Frame Relay
