Chapter 3 Configuring with the Command-Line Interface

Configuring 1-Port G.SHDSL WAN Interface Card

• Configuration Tasks, page 3-60

• Configuration Examples, page 3-64

G.SHDSL is ATM-based, multirate, high-speed (up to 2.3 MB), symmetrical digital subscriber line

digital data transfer between a single customer premises equipment (CPE) subscriber and a central

office.

G.SHDSL is supported on the G.SHDSL WAN interface card, a 1-port WAN interface card (WIC) for

Cisco 2600 series and Cisco 3600 series routers.

The G.SHDSL WIC is compatible with the Cisco 6015, Cisco 6130, Cisco 6160, and Cisco 6260 Digital

Subscriber Line Access Multiplexers (DSLAMs). The DSLAM must be equipped with G.SHDSL line

cards that are compatible with the DSL service to be configured.

The G.SHDSL WIC supports ATM Adaptation Layer 2 (AAL2), ATM Adaptation Layer 5 (AAL5), and

various classes of quality of service (QoS) for both voice and data service.

Listed below are some benefits of this feature:

• Enables business-class broadband service with voice integration, scalable performance, flexibility,

and security.

• Aggregates G.SHDSL and other transport options into a single box.

• Provides G.SHDSL high-speed digital data transmissions between customer premises equipment

(CPE) and the central office (CO), or between routers located within a customer site.

• Supports ITU G.991.2 (SHDSL).

• Supports ANSI T1.601 (BRI), ANSI T1.410 (DDS), and ANSI T1.403 (T1 carrier).

• Supports AAL2 and AAL5 services and applications (including voice), ATM class of service

(constant bit rate [CBR], variable bit rate-nonreal time [VBR-nrt], variable bit rate-real time

[VBR-rt], and unspecified bit rate [UBR and UBR+]), and up to 23 virtual circuits on a WIC in

Cisco 2600 series and Cisco 3600 series routers.

• Provides ATM traffic management and quality of service (QoS) features to enable service providers

to manage their core ATM network infrastructures.

This feature is supported on the following router platforms:

• Cisco 2610

• Cisco 2611

• Cisco 2612

• Cisco 2613

• Cisco 2620

• Cisco 2621

• Cisco 2650

• Cisco 2651

• Cisco 3620

• Cisco 3640

• Cisco 3661

• Cisco 3662
