Feature Overview
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.
1-Port G.SHDSL WAN Interface Card for Cisco 2600 Series Routers
Restrictions
• 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.
• 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.

Configuration Tasks
Command Purpose
Router> show interface atm 1/0
Step 14
Router clear interface atm 1/0
Step 15
Verifies the ATM interface configuration.
Permits the configuration changes to take effect.
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:

12.2(4)XL This command was integrated into Cisco IOS Release 12.2(4)XL on the
G.SHDSL WIC on the Cisco 2600 series routers.
Usage Guidelines This configuration command applies to a specific ATM interface. You must specify the ATM interface
before you enter this command.
The ATM interface must be in the shutdown state before you enter this command.
Examples The following example shows how to configure DSL ATM interface 0/1 to operate at a line rate of 1040
kbps.
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.

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.
Glossary
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.
