Cisco IOS Release 12.2(4)XL

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.

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.

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:

Command Purpose

Router(config)# interface atm 1/0

Step 1

Router(config-if)# ip-address IP-address

Step 2

Router(config-if)# atm ilmi-keepalive

Step 3

seconds

Router(config-if)# pvc [name] vpi/vci

Step 4

Enters ATM configuration mode for interface ATM 0 in slot 1.

Note If a slot has two subslots for WIC modules and no ATM

Assigns an IP address to the DSL ATM interface.

(Optional) Enables Integrated Local Management Interface (ILMI) keepalives.

If you enable ILMI keepalives without specifying the seconds, the default time interval is 3 seconds.

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.

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.

Router(config-if-vc)# protocol ip

Step 5

IP-address

Cisco IOS Release 12.2(4)XL

The default traffic shaping is UBR; the default encapsulation is AAL5+LLC/SNAP.

(Optional) Enables IP connectivity and create a point-to-point IP address for the virtual circuit (VC).

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:

Router# show interface atm 1/0 ATM1/0 is up, line protocol is up Hardware is DSLSAR (with Globespan G.SHDSL Module) MTU 4470 bytes, sub MTU 4470, BW 800 Kbit, DLY 2560 usec, reliability 255/255, txload 1/255, rxload 1/255 Encapsulation ATM, loopback not set Keepalive not supported Encapsulation(s):AAL5 AAL2, PVC mode 24 maximum active VCs, 256 VCs per VP, 2 current VCCs VC idle disconnect time:300 seconds Last input never, output 00:00:01, output hang never Last clearing of "show interface" counters 03:16:00 Queueing strategy:fifo Output queue 0/40, 0 drops; input queue 0/75, 0 drops 30 second input rate 0 bits/sec, 0 packets/sec 30 second output rate 0 bits/sec, 0 packets/sec 2527 packets input, 57116 bytes, 0 no buffer Received 0 broadcasts, 0 runts, 0 giants, 0 throttles 0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort 10798 packets output, 892801 bytes, 0 underruns 0 output errors, 0 collisions, 0 interface resets 0 output buffer failures, 0 output buffers swapped out

• 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
