1-Port G.SHDSL WAN Interface Card for Cisco 2600 Series Routers
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.
•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.
•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.
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)
To configure G.SHDSL service on a Cisco router containing a G.SHDSL WIC, complete the following steps, beginning in global configuration mode:
|
Command |
Purpose |
|
|
|
Step 1 |

Enters ATM configuration mode for interface ATM 0 in slot 1. |
|
|
Note If a slot has two subslots for WIC modules and no ATM |
|
|
interface is present in subslot 0, the WIC will take ATM x/0 |
|
|
as its interface number even if placed in subslot 1 (ATMx/1). |
|
|
If a two-port ATM module is present in subslot 0, the WIC |
|
|
will use ATM x/2 as its interface number. This subslot |
|
|
number is pertainent to all interface commands such as |
|
|
show interface atm and show dsl interface atm. |
|
|
|
Step 2 |
Router(config-if)# ip-address IP-address |
Assigns an IP address to the DSL ATM interface. |
|
|
|
Step 3 |
Router(config-if)# atm ilmi-keepalive |
(Optional) Enables Integrated Local Management Interface (ILMI) |
|

keepalives. |
|
|
If you enable ILMI keepalives without specifying the seconds, the |
|
|
default time interval is 3 seconds. |
|
|
|
Step 4 |
Router(config-if)# pvc [name] vpi/vci |
Enters atm-virtual-circuit (interface-atm-vc) configuration mode, |
|
|
and configures a new ATM permanent virtual circuit (PVC) by |
|
|
assigning a name (optional) and VPI/VCI numbers. |
|
|
The default traffic shaping is UBR; the default encapsulation is |
|
|
AAL5+LLC/SNAP. |
|
|
|
Step 5 |
Router(config-if-vc)# protocol ip |
(Optional) Enables IP connectivity and create a point-to-point IP |
|
IP-address |
address for the virtual circuit (VC). |

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

•To view the status of the G.SHDSL modem, use the show dsl interface atm command. If the line is down, the following statement appears: Line is not active. Some of the values may not be accurate. You can also verify whether the equipment type and operating mode configuration are correct for your application.
Sample output—The WIC is configured as central office equipment, and the line is up
