• Supports Wetting Current (Section A.5.3.3 of G.991.2)

• Supports G.SHDSL Annex A (U.S. signaling) and Annex B (European signaling)

• Supports "Dying Gasp" on HWIC-2SHDSL; uses power status bit (section 7.1.2.5.3 of G.991.2) for signaling

• Offers ability to configure multiple G.SHDSL HWICs per Cisco 1841, 2800, and 3800 Router chassis

• Provides toll-quality voice over data through ATM Adaptation Layer 5 (AAL5) and voice over IP (VoIP) on the Cisco 1841 ISR and the Cisco 2800 and 3800 Series ISRs; note that embedded voice services with digital signal processors, voice and fax modules are supported only on the Cisco 2800 and 3800 Series ISRs.

• Offers extensive ATM class-of-service (CoS) and IP quality-of-service (QoS) support

• Sustains up to 8 permanent virtual circuits (PVCs) per HWIC

• 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 their core ATM network infrastructures to deliver scalable, cost-effective services with QoS guarantees to their customers. Per-virtual-circuit traffic shaping and queuing allows further optimization of the existing bandwidth between customers and various services.

Table 3 later in this document gives a summary of the ATM features, including QoS and traffic management capabilities supported on the G.SHDSL HWICs.

Converged Platform for Small to Medium-Sized Business and Enterprise Branch Applications

The Cisco 1841, 2800, and 3800 Series of Integrated Services Router platforms with the G.SHDSL HWICs provide customers with a choice of converged platforms that offer best-of-class data, security, WAN access, and voice services in a single system. The Cisco 2800 and 3800 Series Routers embed voice functions directly inside the router ,enabling customers to deploy voice services by installing digital signal processors (DSPs) and advanced integration modules (AIMs) for IP telephony conferencing, voice gateways, and Cisco Unity ® Express voicemail and automated attendant. For call processing, customers can enable the Cisco Call Manager Express solution as part of Cisco IOS Software and reconfigure the same software to support Cisco Survivable Remote Site Telephony (SRST) for centralized call processing with Cisco CallManager. Such an integrated solution rapidly enables service deployment, increases efficiency of network operations, and provides opportunities to protect, grow, and optimize the business.
