Configuring Cisco Multimode G.SHDSL EFM/ATM in Cisco ISR G2

OL-24505-04

Last Updated: October 14, 2013

This document describes how to configure Cisco G.SHDSL Ethernet in the first mile (EFM) and Asynchronous Transfer Mode (ATM). Cisco G.SHDSL EFM/ATM Enhanced high-speed WAN interface card (EHWIC) connect Cisco Integrated Services Routers Generation 2 (ISR G2s) with central office Digital Subscriber Line Access Multiplexers (DSLAMs) and provide up to four lines of G.SHDSL (ITU-T 991.2) connectivity. The C888EA provides four pairs of multimode G.SHDSL connectivity.

There is one EHWIC model and one fixed platform model:

•EHWIC-4SHDSL-EA—A double-wide multimode EHWIC G.SHDSL, 4 pair, 802.3ah, EFM and ATM mode interface card

•C888EA—A multimode G.SHDSL, 4 pair 802.3ah, EFM and ATM mode fixed platform

Information About Cisco G.SHDSL EFM/ATM

Cisco G.SHDSL EFM/ATM EHWICs support up to four pairs of digital subscriber lines (DSL). The fixed platform model (C888EA) also supports up to four pairs. The DSL pairs are bundled in groups and configured in the Cisco IOS command-line interface (CLI) by using the dsl-group command. Selecting the mode is done by using the mode command.

See the "Command Reference" section for more information about commands used with Cisco G.SHDSL EFM/ATM.

Cisco G.SHDSL EFM/ATM

The Cisco EHWIC-4SHDSL-EA provides up to four lines of connectivity through one RJ-45 connector (see Figure 1), in EFM or ATM modes. The Cisco 888EA fixed platform (see Figure 2) supports up to four lines of connectivity through one RJ-45 connector, in EFM or ATM modes.

Note The C888EA and the Cisco EHWIC-4SHDSL-EA support 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.

Configuring 2-Wire Non-bonding DSL Group

To configure a 2-wire non-bonding DSL group on a Cisco G.SHDSL EFM/ATM, use the Cisco IOS CLI on the router in global configuration mode. Configuring 2-wire non-bonding DSL group is the same for EFM and ATM modes.

Note For EHWICs, use the three-tuple notation (slot number/subslot number/0). For fixed platforms, use the single-tuple notation (slot number).

SUMMARY STEPS

1. controller shdsl slot number/subslot number/0

2. mode {atm | efm}

3. dsl-group DSL_group_number pairs link-number

4. shdsl rate {number | auto}

DETAILED STEPS
Command

Purpose
Step 1
controller shdsl slot number/subslot number/0
Note For EHWICs, use the three-tuple notation (slot number/subslot number/0) shown here. For fixed platforms, use the single-tuple notation (slot number).

Example:
Router(config)# controller shdsl 0/2/0
Router(config-controller)#
Selects the controller and enters config-controller mode.

See the "controller shdsl" section for more information.
Step 2
mode {atm | efm}
Example:
Router(config-controller)# mode efm
Router(config-controller)#
Selects the mode.
Step 3
dsl-group DSL_group_number pairs link-number 
Example:
Router(config-controller)# dsl-group 0 pairs 0
Router(config-controller)#
Creates a non-bonding DSL group and enters config-controller-dsl-group mode.

See the "dsl-group" section for more information.
Step 4
shdsl rate {number | auto}
Example:
Router(config-controller-dsl-group)# shdsl rate 2048
Router(config-controller-dsl-group)#
For more information, refer to the "Command Reference" 
section.
Defines the SHDSL rate.
Examples

The following examples use the G.SHDSL commands to configure a 2-wire DSL group on a Cisco EHWIC-4SHDSL-EA or C888EA in ATM and EFM modes.

Configuring Bonding Groups in ATM Mode

Use the Cisco IOS CLI on the router in global configuration mode to configure bonding groups in the ATM mode on the Cisco EHWIC-4SHDSL-EA, or on the C888EA. There are two types of bonding groups possible in ATM mode: M-pair and IMA.

Note To ensure a successful bonding group in the ATM mode configuration, confirm that the central office (CO) network equipment that is connected with the Cisco EHWIC-4SHDSL-EA is also configured with the same bonding group type.

Note For EHWICs, use the three-tuple notation (slot number/subslot number/0). For fixed platforms, use the single-tuple notation (slot number).

SUMMARY STEPS

1. controller shdsl slot number / slot number / 0

2. mode atm

3. dsl-group DSL_group_number pairs link {m-pair | ima}

4. shdsl rate {number | auto}

Note Annex and TC-PAM (Trellis Coded Pulse Amplitude Modulation) are not configurable. They are configured automatically according to the central office (CO) settings.

DETAILED STEPS
Command

Purpose
Step 1
For EHWICs:
controller shdsl slot number/subslot number/0
Example:
Router(config)# controller shdsl 0/2/0
Router(config-controller)#
For C888EA fixed platform:
controller shdsl slot number
Example:
Router (config)# controller shdsl 0
Router (config-controller)#
Selects the controller and enters config-controller mode.

See the "controller shdsl" section for more information.
Step 2
mode atm 
Example:
Router(config-controller)# mode atm
Router(config-controller)#
Selects the ATM mode.
Step 3
For M-pair:
dsl-group DSL_group_number pairs link m-pair
Example:
Router(config-controller)# dsl-group 0 pairs 0-1 
m-pair
Router(config-controller-dsl-group)#
For IMA:
dsl-group DSL_group_number pairs link ima
Example:
Router(config-controller)# dsl-group 0 pairs 0-1 
ima
Router(config-controller-dsl-group)#
For M-pair:

Creates an M-pair bonding DSL group and enters config-controller-dsl-group mode.

For IMA:

Creates an IMA DSL group and enters config-controller-dsl-group mode.

See the "dsl-group" section for more information.
Step 4
shdsl rate {number | auto}
Example:
Router(config-controller-dsl-group)# shdsl rate 2048
Router(config-controller-dsl-group)#
For more information, refer to the "Command Reference" 
section.

Configuring Auto Groups in ATM Mode

Use the Cisco IOS CLI on the host router in global configuration mode to configure auto groups in the ATM mode on the Cisco EHWIC-4SHDSL-EA, or on the C888EA.

Note For IMA configurations, do not use dsl-group auto. Instead, use manual IMA configuration. For more information, see the IMA example in the "Configuring Bonding Groups in ATM Mode" section.

Note For EHWICs, use the three-tuple notation (slot number/subslot number/0). For fixed platforms, use the single-tuple notation (slot number).

Firmware Update

This section describes the PHY firmware updates to the Cisco G.SHDSL multimode (ATM and EFM) EHWIC and the Cisco 888EA Integrated Services Router.

System Requirements

This section describes the system requirements for using SOCRATES-4e Firmware Update feature of the Cisco IOS software. This section describes the following:

•Prerequisites

•Upgrading to a New Firmware Release

•Determining the Firmware Version

Prerequisites

The following prerequisites must be met before updating the firmware:

•The package file must be available on the router's flash memory or the USB flash drive's memory.

•Cisco IOS software Release 15.3(3)M or later should be installed.

Upgrading to a New Firmware Release

You can upgrade to a new firmware release using one of the following procedures:

Procedure 1

Step 1 Download the new firmware from the Cisco.com Software Center at: http://software.cisco.com/download/release.html?i=!y&mdfid=284367038&softwareid=284942912&release=1.7.5.0_11175002&os=UnixOrLinux.

Step 2 Copy the firmware to a designated location, either in the router's flash memory or a USB flash drive's memory.

Note If you are using a USB drive, insert the USB flash drive into the router.

Step 3 Configure the router to load the new firmware from the designated location using the following command:
Router# configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#controller shdsl 0/1/0
Router(config-controller)#firmware phy?
filename  filename to read firmware
update   firmware update or downgrade
Router(config-controller)# firmware phy filename ?
flash:      Download fw file name
usbflash0:  Download fw file name
Router(config-controller)#firmware phy filename flash: IDC_1.7.2.6_DFE_FW_BETA_120111A.pkg
Or
Router(config-controller)#firmware phy filename usbflash0: 
IDC_1.7.2.6_DFE_FW_BETA_120111A.pkg
Step 4 Update to the new firmware using one of the following methods:

•Execute the following command:
Router(config-controller)# firmware phy update
Proceed phy firmware update with IDC_1.7.2.6_DFE_FW_BETA_120111A.pkg? [yes/no]:
When you are prompted to confirm whether to proceed with the firmware update, enter yes to proceed.

•Save and reload the router to pick up the new firmware.

Note If you are using a USB drive, ensure that it is always inserted into the router. If it is not, the firmware cannot be downloaded using the firmware that is already configured.

Procedure 2

Step 1 Download the new firmware from the Cisco.com Software Center at: http://software.cisco.com/download/release.html?i=!y&mdfid=284367038&softwareid=284942912&release=1.7.5.0_11175002&os=UnixOrLinux.

Step 2 Copy the firmware to the router's flash memory and specify the destination filename as shdsl_ea_IDC_DFE.pkg.

Step 3 Update to the new firmware using one of the following methods:

•Execute the following command:
Router(config-controller)# firmware phy update 
Proceed phy firmware update with shdsl_ea_IDC_DFE.pkg? [yes/no]:
When you are prompted to confirm whether to proceed with the firmware update, enter yes to proceed.

•Save and reload the router to pick up the new firmware.

Note If shdsl_ea_IDC_DFE_.pkg is present in the router's flash memory, and the CLI filename is not set for the controller, the shdsl_ea controller PHY firmware will be loaded from shdsl_ea_IDC_DFE.pkg.

Determining the Firmware Version

In order to determine the version of the firmware that is currently running, execute the following command and review the PHY source, PHY firmware files, the Integrated Device Control (IDC) firmware version, and the DFE firmware version in the output:

Command

Description

dsl-group

Creates and configures a DSL group.

show running-config

Displays the contents of the currently running configuration file or the configuration for a specific class map, interface, map class, policy map, or VC class.

shdsl rate

To define a symmetric high bit rate digital subscriber line (SHDSL) rate, use the shdsl rate command in the configuration controller DSL group mode.

shdsl rate {number | auto | enhanced}

Syntax Description

number

Specifies the data rate supported for the digital subscriber line (DSL) group.

auto

Specifies the best data rate that can be used for the given configurations at the Central Office (CO) and Customer Premise Equipment (CPE) termination.

enhanced

Specifies the Lantiq extended rate. This option is applicable only for the CO-EFM mode.

Note If annex is F/G/A to F/B-G, and coding is 64 or 128 TC-PAM lines, the shdsl rate enhanced option should be used.

Note The enhanced option is available only if the termination is CO and mode is Ethernet in the first mile (EFM). If the link partner supports Lantiq extension, you can use the enhanced option to train at higher rates. If the link partner does not support Lantiq extension, lines are trained to standard rate based on the annex and Trellis Coded Pulse Amplitude Modulation (TC-PAM).

Command Default

The default keyword is auto.

Command Modes

Configuration controller DSL group (config-controller-dsl-group)

Command History

Release

Modification

15.2(2)T

This command was introduced.

15.3(2)T

This command was modified. The enhanced keyword has been added to support Lantiq extended-rate probing and extended-line probing.

Usage Guidelines

Use the dsl-group command to create a DSL group, and then define the SHDSL line rate using the shdsl rate command.

The recommended configuration for the CPE is shdsl rate auto. When configuring the fixed rate, use the same rate that was used for configuring the CO.

Based on the type of DSL group, the following standard data rates are supported:

DSL Group with 1 Pair

•Annex A and B—192 to 2304 kbps

•Annex F and G (32 TC-PAM)—768 to 5696 kbps

•Annex F and G (16 TC-PAM)—2304 to 3840 kbps

•Annex A to F, and B to G (32 TC-PAM)—768 to 5696 kbps

•Annex A to F, and B to G (16 TC-PAM)—192 to 3840 kbps

DSL Group with 2 Pairs

•Annex A and B— 384 to 4608 kbps

•Annex F and G (32 TC-PAM)—1536 to 11392 kbps

•Annex F and G (16 TC-PAM)—4608 to 7680 kbps

•Annex A to F, and B to G (32 TC-PAM)—1536 to 11392 kbps

•Annex A to F, and B to G (16 TC-PAM)—384 to 7680 kbps

DSL Group with 3 Pairs

•Annex A and B— 576 to 6912 kbps

•Annex F and G (32 TC-PAM)— 2304 to 17088 kbps

•Annex F and G (16 TC-PAM)— 6912 to 11520 kbps

•Annex A to F, and B to G (32 TC-PAM)— 2304 to 17088 kbps

•Annex A to F, and B to G (16 TC-PAM)— 576 to 11520 kbps

DSL Group with 4 Pairs

•Annex A and B— 768 to 9216 kbps

•Annex F and G (32 TC-PAM)— 3072 to 22784 kbps

•Annex F and G (16 TC-PAM)— 9216 to 15360 kbps

•Annex A to F, and B to G (32 TC-PAM)— 3072 to 22784 kbps

•Annex A to F, and B to G (16 TC-PAM)— 768 to 15360 kbps

EFM-Bonding 4 Pairs

The following enhanced rates are supported for the EFM-bonding 4 pairs:

•Annex F and G (128 TC-PAM)— 9248 to 61216 kbps

•Annex F and G (64 TC-PAM)—9216 to 50944 kbps

•Annex A to F, and B to G (128 TC-PAM)— 800 to 61216 kbps

•Annex A to F, and B to G (64 TC-PAM)— 768 to 50944 kbps

For EFM and Inverse Multiplexing Over ATM (IMA) bonding configuration with multiple links, Group Data rate will be the summation of different link rates. Group Data rate falls in one of the above DSL group ranges based on the annex and TC-PAM; different links may train at different rates.

Note In case of CPE annex and coding that is dependent on the configuration during the termination at the CO, select the standard rate at par with the configuration during the termination at the CO.

Note If the CO is configured for Lantiq extensions (128 or 64 coding or extended rate), the CPE lines may not train with the rate configured in the CPE. This CO rate is configured for enhanced rates, as specified above.

For enhanced rate, configure the current and worst-case signal-to-noise ratio (SNR) margins using the shdsl rate enhanced command to enable rate adaption, Power Measurement Modulation Session (PMMS), or line probing.

Command

Description

dsl-group

Creates and configures a DSL group.

shdsl annex

Defines a SHDSL G.991.2 standard

efm-grp link-stability-timer

To configure the data transmission delay period for links in an Ethernet in the First Mile Bonding (EFM-Bonding) group, use the efm-grp link-stability-timer command in the configuration controller DSL group mode.

efm-grp link-stability-timer seconds

Syntax Description

seconds

Data transmission delay, in seconds. The range is from 0 to 60. The default is 0.

Command Default

None

Command Modes

Configuration controller DSL group (config-controller-dsl-group)

Command History

Release

Modification

15.3(2)T

This command was introduced.

Usage Guidelines

The link stability timer is supported only on Customer Premise Equipment (CPE) for interoperability with Digital Subscriber Line Access Multiplexers (DSLAMs), such as Overture HN4000, that support data transmission delay of a few seconds to dampen out unstable links in scenarios where demanding circumstances, such as lightning, long multirepeater spans, and so on, prevail. The link stability timer introduces a data transmission delay in the user-configured value after the links are in the UP_DATA mode in order to achieve a stable SYNC status with the DSLAM.

The Link Stability feature enables interoperability with the Overture DSLAM. After a 2 bpme (BASE-TL PME) reaches the data mode, the HN4000 (Overture DSLAM) waits for approximately 13 seconds before checking for the 64/65 lock. Due to this, whenever a link is added to an existing bonding group, network traffic stops completely for about 13 seconds. Hence, the optimal link stability value for the Overture DSLAM is set at 13 seconds to avoid packet drops in the DSLAM.

For other DSLAMs that do not exhibit this behavior, the link stability duration can be set to 0 seconds, the default value during the termination at the CPE.

Examples

The following example shows how to use the efm-grp link-stability-timer command:
Router(config-controller-dsl-group)# efm-grp link-stability-timer ?

efm-grp minimum-links

To configure the minimum number of active links for an Ethernet in the first mile (EFM) group to be up, along with a timeout value, use the efm-grp minimum-links command in the configuration controller DSL group mode.

efm-grp minimum-links minimum-links timeout seconds

Note The efm-grp minimum-links command is supported only on the Customer Premise Equipment (CPE).

Syntax Description

minimum-links

Minimum number of links that must be up in an EFM group. The range is from 1 to 4. The default is 1.

seconds

Interval before the group goes down when the minimum number of links are not available, in seconds. The range is from 1 to 300. The default is 0.

Command Default

None

Modification

15.2(2)T

This command was introduced.

15.3(2)T

This command has been modified. The timeout keyword was added to set an interval before the EFM group goes down.

Usage Guidelines

Use the dsl-group command to create a digital subscriber line (DSL) group, and then use the efm-grp minimum-links command to define the minimum number of links required for the EFM group to be up.

After the EFM group is up, if the number of active links falls below the configured number of minimum links for an interval within the timeout period (if configured), failure is ignored. If the failure time exceeds the timeout period, the EFM group goes down.

Examples

The following example shows how to use the efm-grp minimum-links command:
Router(config-controller-dsl-group)# efm-grp minimum-links ?
  <1-4>  Minimum links
Router(config-controller-dsl-group)# efm-grp minimum-links ?
  timeout  interval before group DOWN on minimum link unavailability

Description

dsl-group

Creates and configures a DSL group.

handshake

To configure a handshake, use the handshake command in the configuration controller DSL group mode.

handshake [auto | g.shdsl | g.shdsl.bis | ieee | itut]

Note The handshake command is not available in the CO-ATM mode.

Syntax Description

auto

Specifies automatic detection of G.SHDSL or G.SHDSL.BIS rates.

Note If termination occurs at the Customer Premise Equipment (CPE), regardless of whether the controller is in the CPE-ATM mode or the Ethernet in first mile (EFM) mode, the auto keyword is the default.

g.shdsl

Initiates the G.SHDSL handshake. This is supported on the CPE-ATM mode only.

g.shdsl.bis

Initiates the G.SHDSL.BIS handshake. This is supported on the CPE-ATM mode only.

ieee

Initiates the Institute of Electrical and Electronics Engineers (IEEE) handshake. This is supported on the EFM mode only.

itut

Initiates the ITU Telecommunication Standardization Sector (ITU-T) handshake. This is supported on the EFM mode only.

Note If termination occurs in the CO-EFM mode, the itut keyword is the default.

Command Default

None

Command Modes

Configuration controller DSL group (config-controller-dsl-group)

Command History

Release

Modification

15.2(2)T

This command was introduced.

15.3(2)T

This command was modified to include support for the CO.

Usage Guidelines

The handshake command is useful when you encounter interoperability issues with different DSLAMs. When terminations at the CO and CPE have the same handshake mechanism, the line will train faster without interoperability issues.

For better interoperability with different DSLAMs, use one of the following options with the handshake auto command.

•In the CPE-ATM mode:

–If DSLAM supports G.SHDSL rates, use the g.shdsl keyword.

–If DSLAM supports G.SHDSL.BIS rates, use the g.shdsl.bis keyword.

•In the EFM mode:

–To avoid interoperability issues, use the handshake command along with the keyword that matches the configuration that is in place during the termination at the CO.

Examples

The following example shows how to use the handshake auto command:
Router(config-controller-dsl-group)# handshake ? 
auto Initiate auto handshake
ieee Initiate IEEE handshake
itut Initiate ITUT handshake
shdsl 4-wire mode

To enable the symmetric high bit rate digital subscriber line (SHDSL) to use the enhanced mode in a 2-pair digital subscriber line (DSL) group, use the shdsl 4-wire mode enhanced command in the configuration controller DSL group mode. To disable the shdsl 4-wire mode, use the no form of this command.

shdsl 4-wire mode enhanced

no shdsl 4-wire mode enhanced

Modification

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.

Added dsl-group pairs link-number [efm-bond] for the Cisco HWIC-4SHDSL-E.

15.1(1)T1

This command was modified. The auto configuration options default and shdsl were added to the dsl-group.

15.2(2)T

This command was modified to support the Cisco EHWIC-4SHDSL-EA and Cisco 888-EA. The configuration options ignore and shutdown were added.

Usage Guidelines

Use the dsl-group command in configuration controller mode to define the DSL group and manually configure the DSL group from configuration controller mode. Use the dsl-group auto command to automatically adopt the Central Office (CO) wire configuration on an ATM DSL group (EHWIC-4SHDSL-EA, HWIC-4SHDSL) or EFM DSL group (EHWIC-4SHDSL-EA). Use the dsl-group pairs to define the DSL group as Ethernet First Mile (EFM) bonding group (HWIC-4SHDSL-E, EHWIC-4SHDSL-EA) or ATM DSL group (EHWIC-4SHDSL-EA).

Note Automatic configuration is not supported on IMA groups.

Automatic configuration is limited to only one DSL group and ATM interface (EHWIC-4SHDSL-EA, HWIC-4SHDSL) or Ethernet interface (EHWIC-4SHDSL-EA). After a group is automatically configured, no other group can be created. All manually created groups must be deleted before creating an automatic configuration group.
