Feature Summary

The Cisco 1700 combined with the WIC-1SHDSL provides:

• Symmetrical WAN speeds (up to 2.3 Mbps) over a single copper pair

• Multiple G.shdsl WICs per Cisco 1700 chassis

• Support for voice over IP (VoIP) over DSL with IP quality of service (QoS)

• Support for IP QoS map to ATM class of service (CoS)

• Back-to-back operation or operation via DSL access multiplexer (DSLAM)

• Support for up to 23 virtual circuits per WIC

Key Benefits: Business Class DSL

Symmetrical, High-Speed, Cost-Effective Bandwidth

Based on the ITU G.991.2 global industry standard, the Cisco G.shdsl solution delivers symmetrical data rates from 192

kbps up to 2.3 Mbps. Speeds vary, depending on the loop length and line conditions. More traditional WAN links, such as

leased-line and ISDN, provide similar service, but often at a much higher monthly cost. The G.shdsl WIC delivers

symmetrical connectivity and provides the necessary bandwidth for business applications such as VoIP, videoconferencing,

and toll bypass at a lower monthly charge.

The dualWAN ports on the Cisco 1700 Series platforms allow for ﬂexibility in installing WAN access lines. Multiple G.shdsl

WICs can be conﬁgured per router chassis to provide additional bandwidth through a second WAN link, and supply

connectivity to additional sites or service providers. With the broad array of WICs available for the Cisco 1700 platform,

ﬂexible conﬁgurations, including asymmetric DSL (ADSL), dial, ISDN, E1/T1, and Frame Relay are also possible. Secondary

WAN links can, therefore, be used to provide more available bandwidth or redundancy for mission-critical applications.

Business-Class Security

The Cisco 1700 can be optimized for virtual private networks (VPNs). VPNs allow for secure use of any shared network

incorporating the same policies and levels of security and performance as a private network. The Cisco 1700 Series provides

(IPSec) speeds of up to wire speed (T1/E1). VPN capability over G.shdsl allows for secure access to corporate networks

without the costs and limitations associated with point-to-point links.

In addition, the Cisco 1700 Series incorporates Cisco IOS

Firewall Technology (Cisco Secure Integrated Software)

supporting stateful ﬁrewall and intrusion-detection functionality. With an always-on DSL connection, Internet security is a

critical component in protecting corporate resources from malicious attacks.

Integrated Voice and Data over G.shdsl

Service providers increase revenue by building differentiated service options based on premium, standard, or best-effort

serviceclasses.This requires a QoSmechanismto differentiate servicelevelsand prioritize trafﬁcaccordingly.The Cisco 1700

with G.shdsl WIC provides ATM CoS features that enable service providers to manage their core ATM network

infrastructures and deliver scalable, cost-effective services with QoS guarantees to their customers. Permanent-virtual-circuit

(PVC) trafﬁc shaping and queuing allow further optimization of the existing bandwidth between customers and various

services.
