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 ReservationProtocol (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

packetsor Frames, and prioritized overother data trafﬁcfora 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. The new Data Encryption AIM enhances this ﬂexibility by using

optional hardware-based encryption services by ofﬂoading the encryption processing from the Cisco 2600 series Central

Processing Unit (CPU), providing 10-times the performance over software-only encryption.

For example, a Cisco 2610 router inthe branch ofﬁce can provide secure privileged access to business partners while also

supporting another connection to a Cisco 2621 or Cisco 2651 in the main ofﬁce. The dual-LAN architecture of the Cisco

2621 and the Cisco 2651, 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 or Cisco 2651 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 trafﬁcfrom a wide variety of serial devicesover 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
