Encryption Performance—The Cisco 1720 router

currently supports software-based encryption and will

support hardware-based encryption in the future. Powered

by a RISC processor, the Cisco 1720 supports IPSec

software-based encryption at 512 kbps for 256-byte packets

(typical packet size for most networks). (Performance may

vary, depending on the encryption algorithm used, network

packet sizes, and so on) An expansion slot on the

motherboard of the Cisco 1720 allows for support of future

hardware-assisted services such as encryption (up to T1/E1)

and compression.

Flexibility

To protect their investment against the constant change in

networkingrequirements,companies needaproductthatcan

adapt. The Cisco 1720 router provides the most ﬂexible

solution for small/medium businesses and small branch

ofﬁces.

Modular WAN interface cards—All WAN interfaces on

the Cisco 1720 are interchangeable through the two WAN

slots. Customers can mix and match whichever WAN

interface card combination they want, allowing them to

upgrade or change WAN technologies as needed. A wide

range of WAN options are available, including dual ISDN

BRI, up to ﬁve ports for serial aggregation, and integrated

DSU/CSUs up to T1 speed.

Shared WAN interface cards with Cisco 1600, 2600,

and 3600 routers—Shared WAN interface cards enhance the

investment-protection value of the routers and WAN

interface cards. When a card is no longer needed in one

platform, it can be reused on another platform. Also,

customers, resellers, and service providers who keep spare

WIC cards canreduce the numberof stock-keeping units and

inventory.

Autosensing10/100 Fast Ethernet—The Cisco1720 has

anautosensing10/100FastEthernetport that allows for easy

migrationtoFastEthernetnetworks. Simply plug in the LAN

cable and this port automatically detects whether the LAN

speed ought to be 10 or 100 Mbps and automatically

negotiates simplex or duplex mode. For ofﬁces with

100BaseTX hubs, the autosensing 10/100 port of the Cisco

1720 eliminates the need for a 10/100 bridge.

Performanceforemergingbroadbandtechnologies—The

RISC processor of the Cisco 1720 gives it the performance

necessary to support emerging broadband technologies such

asdigitalsubscriberline(DSL)inthefuture.Cisco’sroadmap

for future WAN interface cards includes DSL technology.

Network Device Integration

Integrating multiple functions into a single device reduces

deploymentandmanagementtimeandcosts.TheCisco1720

router provides all-in-one integration advantages in

two ways:

Integrated devices in a single box—The Cisco 1720 is

capable of combining multiple functions, including router,

ﬁrewall, encryption, VPN tunnel server (home gateway),

DSU/CSU, and Network Termination 1 (NT1). Beneﬁts

include:

• Simpliﬁed support and reduced costs because

function

• Simpliﬁed VPN conﬁguration: Cisco IOS software support

for VPN tunneling suchas L2TP is integrated withsecurity

features such as IPSec encryption and user authentication

• Fewer devices and cables to install and conﬁgure

• Enhanced reliability (fewer components such as power

supplies)

• Physical space savings

Integrated Single-Vendor LAN/WAN Solution: Cisco

Networked Ofﬁce Stack—Small- and medium-sized

businesses, which typically have little or no network

administration resources, beneﬁt from deploying integrated

solutions with LAN and WAN components from a single

vendor that work together easily and seamlessly. Further,

with single-vendor solutions, only a single phone call is

necessary when support is needed. The Cisco 1720 router is

a member of the Cisco Networked Ofﬁce (CNO)

stack—Cisco’s integrated LAN/WAN solution. Other CNO

components include the Cisco 1600 series routers, Cisco IOS

Firewall feature set, Cisco 1528 10/100 hub, Cisco 1548 10/

100 switch, and Cisco ConﬁgMaker network conﬁguration

tool.
