1-Port G.SHDSL WAN Interface Card for Cisco 2600 Series Routers
Feature History
Release Modification12.2(4)XL
This feature was integrated into Cisco IOS Release 12.2(4)XL for Cisco 2600 series routers.
This document describes the Multirate Symmetrical High-Speed Digital Subscriber Line (G.SHDSL) feature supported on the 1-port G.SHDSL WAN interface card (WIC) (WIC-1SHDSL) on Cisco 2600 series routers in Cisco IOS Release 12.2(4)XL. This document describes the benefits of the new feature, supported platforms, configuration, and related documents and provides command reference information.
This document includes the following sections:
•Supported Standards, MIBs, and RFCs
Feature Overview
G.SHDSL is ATM-based, multirate, high-speed (up to 2.3 MB), symmetrical digital subscriber line technology for 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 (WIC-1SHDSL), a 1-port WAN interface card (WIC) for Cisco 2600 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.
Benefits
•Enables business-class broadband service with voice integration, scalable performance, flexibility, and security.
•Symmetrical WAN speeds (up to 2.3Mbps) over a single copper pair.
•Repeatable and has thirty percent longer reach than SDSL.
•Rate adaptive with G.HS "handshake" Protocol.
•Based on ITU Recommendation G.991.2 (Accepted Worldwide).
•Support for G.SHDSL Annex A (U.S. signaling) and Annex B (European signaling).
•Multiple G.SHDSL WAN Interface Cards configurable per Cisco 2600 series chassis.
•Toll-quality voice over delivery over AAL2, AAL5, and VoIP.
•Provides ATM traffic management and quality of service (QoS) features to enable service providers to manage their core ATM network infrastructures.
•Critical IP QoS features.
•Supports ATM class of service features 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+).
•Operates back-to-back or through a DSLAM.
•Sustains up to 23 virtual circuits Per WAN on a WIC in Cisco 2600 series routers.
Restrictions
•The G.SHDSL WIC does not support dual latency. When the DSL link is intended to support both voice and data traffic simultaneously, the total supported data rate must be reduced to adjust for the reduced coding gain, which is usually present with high-latency traffic.
•The G.SHDSL WIC does not support Dying Gasp in ANSI T1.413 Issue 2.
•The G.SHDSL WIC does not support available bit rate (ABR) class of service (CoS).
•The G.SHDSL WIC should be inserted only into onboard WIC slots or 1FE2W network modules. This WIC is not supported in old combination network modules.

Prerequisites
A G.SHDSL WIC must be installed in the router to match the DSL service to be configured. A compatible G.SHDSL line card must be installed in the DSLAM.
Configuration Tasks
See the following sections for configuration tasks for this feature. Each task in the list is identified as either required or optional:
•Configuring G.SHDSL on a Cisco Router (required)
•Configuring ILMI on the DSLAM Connected to the G.SHDSL WIC (optional)
•Verifying ATM Configuration (optional)
Configuring G.SHDSL on a Cisco Router
To configure G.SHDSL service on a Cisco router containing a G.SHDSL WIC, complete the following steps, beginning in global configuration mode:
Configuring ILMI on the DSLAM Connected to the G.SHDSL WIC
The ILMI protocol allows DSLAMs to be used for ATM address registration across an ATM User-Network Interface (UNI). If ILMI is configured on the G.SHDSL WIC, the ATM PVC must be configured on the DSLAM. All switch terminating connections use interface 0/0 to connect to the switch CPU.
For information about configuring the DSLAM, see the Configuration Guide for Cisco DSLAMs with NI-2.
Verifying ATM Configuration
Use the following commands to verify your configuration:
•To verify current configuration and to view the status for all controllers, use the show running-config command.
•To view ATM controller statistics, use the show controllers atm slot/port command.
•To verify the PVC status, use the show atm vc command. Make sure that active PVCs are up.
•To help identify ATM related events as they are generated, use the debug atm events command.
•To indicate which interfaces are having trouble, use the debug atm errors command.
•To identify an entry for the ATM interface you configured and to show an entry for the ATM slot/port you configured, use the show ip route command.
•To view the status of ATM interface, use the show interface atm command. Make sure that the ATM slot/port and the line protocol are up, as shown in the following example:

Glossary
ABR—available bit rate.
ADSL—asymmetric digital subscriber line (ADSL) available through several telecommunications carriers to accommodate the need for increased bandwidth for Internet access and telecommuting applications.
ATM—Asynchronous Transfer Mode. International standard for cell relay in which multiple service types (such as voice, video, or data) are conveyed in fixed-length (53-byte) cells. Fixed-length cells allow cell processing to occur in hardware, thereby reducing transit delays. ATM is designed to take advantage of high-speed transmission media such as E3, SONET, and T3.
CLI—command-line interface.
CO—Central office, or local exchange (local switch), which terminates individual local telephone subscriber lines for switching, and connects to the public network. Known as a class 5 switch office. For example, 5ESS by Lucent and DMS 100 by Nortel.
CPE—customer premise equipment, including devices such as channel service units (CSUs)/data service units (DSUs), modems, and ISDN terminal adapters, required to provide an electromagnetic termination for wide-area network circuits before connecting to the router or access server. This equipment was historically provided by the telephone company, but is now typically provided by the customer in North American markets.
DSL—digital subscriber line available through several telecommunications carriers to accommodate the need for increased bandwidth for Internet access and telecommuting applications.
FXO—foreign exchange office. A FXO interface connects to a central office.
FXS—foreign exchange station: A FXS interface connects directly to a standard telephone, supplying ring voltage, dial tone, etc.
G.SHDSL—Multirate Symmetrical High-Speed Digital Subscriber Line
IAD—integrated access device. A CPE device used to combine services from various sources onto a common platform for transmission on a common transport span. Typically, an IAD combines various voice and data services such as circuit-based services like traditional POTS and packet-switched services such as frame relay or ATM.
PVC—permanent virtual circuit.
