voice-enabled applications such as integrated

messaging and Web-based call centers. The

Cisco 1750 works with the existing telephone

infrastructure—phones, fax machines, key

telephone systems (KTS) units, and

PBX—minimizing capital costs.

• Lower Cost of Ownership—The Cisco 1750 router

provides a complete solution for integrated voice and

data access in a single product, eliminating the need to

install and maintain a large number of separate

devices. You can combine optional functions,

including a voice gateway, dynamic ﬁrewall, VPN

tunnel server, DSU/CSU, ISDN network termination-1

(NT1) device, and more to reduce deployment and

management costs. This solution can be managed

remotely using network management applications

such as CiscoWorks and CiscoView or any

SNMP-based management tool.

• Investment Protection—The Cisco 1750 RISC

architecture, Cisco IOS software, and modular slots

provide solid investment protection to companies that

want a platform that offers data connectivity today

and an easy migration path to implement services such

as multiservice data/voice/video integration, VPNs,

and broadband DSL and cable communications in the

near future. A slot on the 1700 series motherboard

offers the ability to support future hardware-assisted

data encryption at T1/E1 speeds.

Cisco IOS Technology

Internet and Intranet Access

Cisco IOS software provides an extensive set of features

that make the Cisco 1750 router ideal for ﬂexible,

high-performance communications across both intranets

and the Internet:

• Multiprotocol routing (IP, IPX, and AppleTalk), IBM/

SNA, and transparent bridging over ISDN,

asynchronous serial, and synchronous serial such as

leased lines, Frame Relay, SMDS, Switched 56, X.25,

and X.25 over D

• WAN optimization—including dial-on-demand

routing (DDR), bandwidth-on-demand (BOD) and

OSPF-on-demand circuit, Snapshot routing,

compression, ﬁltering, and spooﬁng to reduce

WAN costs

Security

Cisco IOS software supports an extensive set of basic and

advanced network security features, including access

control lists (ACLs), user authentication, authorization,

and accounting (such as PAP/CHAP, TACACS+, and

RADIUS), and data encryption. To increase security, the

integrated Cisco IOS Firewall Feature Set protects internal

LANs from attacks with context-based access control

(CBAC), while IPSec tunneling with data encryption

standard (DES) and triple DES encryption provide

standards-based data privacy, integrity, and authenticity

as data travels through a public network.

For remote access VPNs, Layer 2 Forwarding (L2F) and

Layer 2 Tunneling Protocol (L2TP) combine with IPSec

encryption to provide a secure multiprotocol solution (for

IP, IPX, and AppleTalk trafﬁc, and more). Mobile users

can dial in to a service provider's local point of presence

(POP) and data is "tunneled" (or encapsulated inside a

second protocol such as IPSec or L2TP) back to the Cisco

1750 router to securely access the corporate network via

the Internet.

Cisco IOS Software QoS Features

Through Cisco IOS software, the Cisco 1750 router

delivers quality of service (QoS) capabilities, including

Resource ReSerVation Protocol (RSVP), Weighted Fair

Queuing (WFQ), Committed Access Rate (CAR), IP

Precedence, DSCP Marking, Compressed RTP (cRTP),

multiple link PPP (MLPPP) and link framentation and

interleaving (LFI). These features enable businesses to

prioritize trafﬁc on their networks by user, application,

trafﬁc type, and other parameters, to ensure that

business-critical data and delay-sensitive voice receive the

priority they need as they move across the network.

Because the Cisco 1750 router provides robust voice

compression, up to six voice calls can occupy a single 64K

data channel simultaneously, without compromising data
