Data Sheet

●

Provides single RJ-11 connector on 2-pair HWIC (HWIC-2SHDSL) and single RJ-45

connector on 4-pair HWIC (HWIC-4SHDSL)

System Requirements

●

The 2- and 4-pair G.SHDSL HWICs are supported on all modular Cisco Integrated Services

Routers: the Cisco 1841, 2801, 2811, 2821, 2851, 3825, and 3845.

●

The 2- and 4-pair G.SHDSL HWICs are supported in all Cisco IOS

Software feature sets.

●

The routers listed previously need to run Cisco IOS Software Special Release 12.4(11)XJ

to support the 2- and 4-pair G.SHDSL HWICs. They will also be supported on the Cisco

IOS Software Release 12.4(6th)T and later.

●

The system requires no additional flash or DRAM memory other than the specified

minimum memory for the previously mentioned Cisco IOS Software releases.

●

The 2- and 4-pair G.SHDSL HWICs can be inserted into any HWIC slot in the integrated

services routers.

Cisco Integrated Services Router with G.SHDSL HWIC Applications

Business-Class DSL with Backup WAN

The Cisco Integrated Services Routers with the 2-pair and 4-pair G.SHDSL HWICs provide a

business-class DSL solution for WAN access along with the option of a backup WAN interface

(asymmetric DSL [ADSL] and ADSL2+, ISDN Basic Rate Interface [BRI], T1/E1, analog modem,

cable modem, etc.) for mission-critical applications. The IMA feature offered on the 4-pair

symmetric G.SHDSL HWIC allows service providers to bond two or more pairs of G.SHDSL links

to offer differentiated bandwidth based on service-level agreements.

Business-Class Security

The Cisco 1841 Integrated Services Router and the Cisco 2800 and 3800 Series of Integrated

Services Routers with the G.SHDSL HWICs can be optimized for Internet security with the Cisco

IOS Firewall supporting stateful inspection firewall and intrusion prevention system features.

These platforms can also be optimized for VPNs, which allow secure use of the Internet for

communications with the same policies and levels of security and performance as a private

network. VPNs provide security through encryption tunneling, and the Cisco routers support

hardware-based Triple Data Encryption Standard (3DES) IP Security (IPSec), Advanced

Encryption Standard (AES), and Secure Sockets Layer VPN (SSL VPN). Encryption features

can be enabled on the routers with the Advanced Security or any higher feature set of the

Cisco IOS Software.

Differentiated Service Offerings through IP and ATM QoS

Using Cisco QoS features including Class-Based Weighted Fair Queuing (CBWFQ), Low-Latency

Queuing (LLQ), Weighted Random Early Detection (WRED), etc., the Cisco 1841 Integrated

Services Router and the Cisco 2800 and 3800 Series of Integrated Services Routers with

G.SHDSL HWICs help service providers and resellers offer services that can differentiate

bandwidth based on a specific application or a specific user.

In addition to IP QoS features, the Cisco 1841, 2800, and 3800 Series of Integrated Services

Routers with the G.SHDSL HWICs map IP QoS to ATM CoS features, including support for

constant bit rate (CBR), Variable Bit Rate non-realtime (VBR-nrt), Variable Bit Rate realtime

(VBR-rt), Unspecified Bit Rate (UBR), and UBR+. These features help service providers manage
