Configuring Cisco G.SHDSL EFM HWICs in Cisco Routers
First Published: March 19, 2010 OL-20837-01
This document describes how to configure Cisco G.SHDSL Ethernet first mile (EFM) high-speed WAN interface cards (HWICs). Cisco G.SHDSL EFM HWICs connect Cisco integrated services routers (ISR) with central office digital subscriber line access multiplexers (DSLAMs) and provide as many as four lines of G.SHDSL (ITU-T 991.2) connectivity.
Finding Support Information for Platforms and Cisco IOS Software Images
Use Cisco Feature Navigator to find information about platform support and Cisco IOS software image support. Access Cisco Feature Navigator at http://www.cisco.com/go/fn. You must have an account on Cisco.com. If you do not have an account or have forgotten your username or password, click Cancel at the login dialog box and follow the instructions that appear.
Cisco G.SHDSL EFM HWICs support up to four pairs of digital subscriber lines (DSL). The four DSL pairs are bundled in groups and configured in the Cisco IOS command-line interface (CLI) by using the dsl-group command.
Note The Cisco HWIC-4SHDSL-E provides support for the Dying Gasp feature. The term dying gasp refers to power status as defined in ITU-T standard G.991.2, section 7.1.2.5.3.
EN/LP
Status of the system:
Green—Operating system is running.
Amber—Loopback mode.
L0, L1, L2, L3
Status of link:
Green on—Link is active.
Off—Link is inactive or not configured.
Amber—Link alarm
Blinking green—Link is training.
Amber and green blinking simultaneously—Loopback mode. EN/LP is also amber.
Connect Cisco G.SHDSL EFM HWICs through a standard RJ-45 straight-through cable to establish connection between the HWIC and a network device.
Figure 2 shows the RJ-45 pin assignment. Table 1 identifies the RJ-45 signal assignment by pin.
Caution Inserting an RJ-11 connector into the Cisco HWIC-4SHDSL-E port may deform pins 1 and 8, which may prevent solid contact between the connector and the plug in subsequent connections. If solid contact is prevented, line -1 tip and line -3 ring do not work properly.

Note Do not plug in RJ-11 cable into HWIC-SHDSL-E because it may damage the pins on the RJ-45 connector
To connect the Cisco HWIC-4SHDSL-E with a DSLAM that supports two or four RJ-11 connections, modify the standard RJ-45 cable, using one of the following diagrams as applicable:
Figure 3 shows how to modify the cable and connect the Cisco HWIC-4SHDSL-E with a DSLAM that supports four RJ-11 cable connections.
Figure 4 shows how to modify the cable and connect the Cisco HWIC-4SHDSL-E with a DSLAM that supports two RJ-11 cable connections.
Figure 3 Standard RJ-45 Connector to Four Standard RJ-11 Connectors
Figure 4 Standard RJ-45 Connector to Two Standard RJ-11 Connectors
Use the Cisco IOS CLI on the router in global configuration mode to configure an EFM-Bonding group on the Cisco HWIC-4SHDSL-E.
Note To ensure a successful efm-bonding group configuration, confirm that the central office (CO) network equipment that is connected with the Cisco HWIC-4SHDSL-E supports efm-bonding.

Selects the controller and enters config-controller mode.
To troubleshoot Cisco G.SHDSL EFM HWICs, use the following new and published Cisco IOS commands. All other Cisco IOS software commands used with G.SHDSL EFM HWICs are documented in the Cisco IOS Release 15.1(1)T command reference publication at Cisco.com: http://www.cisco.com/en/US/products/ps6441/tsd_products_support_series_home.html
SUMMARY STEPS
1. show controllers shdsl

DETAILED STEPS
Command
Purpose
Step 1
show controllers shdsl slot number/subslot number/0 [detailed | brief]
Example:
Router# show controllers shdsl 0/2/0 detailed
0 output buffer failures, 0 output buffers swapped out
To display link training related events as they are generated, use the debug shdsl-efm training command.
To enable firmware logs, use the debug shdsl-efm firmware command. To display firmware logs, use the show shdsl-efm firmware command.
To dump the chipset memory, follow the steps below.
– debug shdsl-efm firmware
– enable "service internal" in configuration terminal prompt
– show shdsl-efm dspreg
Use the following debug commands for further debugging:
debug shdsl-efm error
debug shdsl-efm driver
debug shdsl-efm eoc
Note For the debug shdsl-efm eoc command, we recommended that the debugs are buffered using the no logging console and logging buffered commands in privileged configuration mode, otherwise the IOS console is flooded with eoc messages.
The efm-grp command is used to perform the necessary link operations (add, delete, and shutdown) of a single link after the creation of efm-bonding group. To perform the link operations in the efm-grp command, enter the config-controller-dsl-group mode. Use the no form of the command to shut down the related command.
efm-grp [ add | delete | shutdown ] link { link number }
no efm-grp [ add | delete | shutdown ] link { link number }
Syntax Description
link number

12.4(15)T
This command was introduced for the Cisco HWIC-4SHDSL and HWIC-2SHDSL running on the Cisco 1841 router and the Cisco 2800 and 3800 series access routers.
15.1(1)T
This command was modified to support automatic configuration of Cisco HWIC-4SHDSL and HWIC-2SHDSL running on the Cisco 1841 router and the Cisco 2800 and 3800 series access routers.
15.1(1)T
This command was modified. Added dsl-group pairs link number [efm-bond] for the Cisco HWIC-4SHDSL-E.
Usage Guidelines
From config-controller mode, use the dsl-group command to define the dsl group, and manually configure the DSL group from config-controller-dsl-group mode. Use the dsl-group auto command to automatically adopt the Central Office (CO) configuration on an ATM dsl-group. Use the dsl-group pairs to define the DSL group as Ethernet First Mile (EFM) group bonding group.
Note Automatic configuration is not supported on IMA groups.
Automatic configuration is limited to only one DSL group and ATM interface. Once a group is automatically configured, no other group can be created. All manually created groups must be deleted before creating an automatic configuration group.
When the CO is running more than one configuration, the CPE will select the configuration based on the following priority:
4. M-PAIR
5. 4-WIRE
6. 2-WIRE
When the CO is running more than one configuration of the same type, the CPE selects the configuration with link 0.
Examples
The following example uses the dsl-group command to create an IMA-DSL group and enter config-controller-dsl-group mode:
Router(config-controller)# dsl-group 1 pairs 0-1 ima
Router(config-controller-dsl-group)#
Sep 14 13:15:40.285:%HWIC_SHDSL-5-DSLGROUP_UPDOWN: SHDSL 0/2/0 dsl-group(1) state changed to down.
Sep 14 13:15:42.285:%LINK-3-UPDOWN: Interface ATM0/2/IMA1, changed state to down
Sep 14 13:15:43.285:%LINEPROTO-5-UPDOWN: Line protocol on Interface ATM0/2/IMA1, changed state to down
The following example uses the dsl-group auto command to automatically adopt the Central Office (CO) configuration on an ATM group:
Router(config-controller)#dsl-group auto
Router(config-controller)#
*May 14 18:56:33.136: %HWIC_SHDSL-5-DSLGROUP_UPDOWN: SHDSL 0/0/0 dsl-group(0) state changed to down.
*May 14 18:56:35.136: %LINK-3-UPDOWN: Interface ATM0/0/0, changed state to down
*May 14 18:56:36.136: %LINEPROTO-5-UPDOWN: Line protocol on Interface ATM0/0/0,
changed state to down
The following example configures a single-pair DSL group and enters the config-controller-dsl-group mode:
Router(config-controller)#dsl-group pairs 0
Router(config-controller-dsl-group)#
