Prerequisites for Cisco G.SHDSL HWICs

Ensure that you have the appropriate Cisco access router to serve as the host router.
The following Cisco access routers support Cisco G.SHDSL HWICs.

Cisco 1841

Cisco 2800 series

Cisco 3800 series

Use the show version command to ensure that the router is running Cisco IOS Release12.4(11) XJ or a later release.


Note When minimum release requirements are met, you can change images on the router without affecting performance.


Install the Cisco G.SHDSL HWIC on the router, using the directions provided in the Cisco Interface Cards for Cisco Access Routers document, http://www.cisco.com/en/US/docs/routers/access/interfaces/ic/hardware/installation/guide/oview_ic.html

Information About Cisco G.SHDSL HWICs

Cisco G.SHDSL HWICs support up to four pairs of digital subscriber lines (DSL): two inverse multiplexing over ATM (IMA) lines, and two ATM segmentation and reassembly (SAR) lines. The four DSL pairs are bundled in groups and configured in the Cisco IOS command-line interface (CLI) by using the dsl-group command.

G.SHDSL HWICs support the following DSL groups:

Inverse Multiplexing over ATM (IMA) groups—1- 4 DSL pairs

Multi-Pair Operation (M-Pair) groups—2 or more DSL pairs

2-Pair groups—2 DSL pairs

1-Pair groups—1 DSL pair

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

Cisco G.SHDSL HWICs

Cisco G.SHDSL HWICs are available in two variations:

The Cisco HWIC-2SHDSL (Figure 1) provides two lines of connectivity through one RJ-11 connector. It supports 1-Pair groups or 2-Pair groups.

Figure 1

Cisco HWIC-2SHDSL Faceplate

The Cisco HWIC-4SHDSL (Figure 2) provides four lines of connectivity through one RJ-45 connector. It combines four lines of data into one line or two lines with either inverse multiplexing over ATM (IMA) groups or M-pair groups, and it supports 1-Pair groups or 2-Pair groups.

Figure 2

Cisco HWIC-4SHDSL Faceplate


Note The Cisco HWIC-2SHDSL provides support for the Dying Gasp feature; however, the Cisco HWIC-4SHDSL does not provide support for this 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

Status of the system:

Green—Operating system is running.

Amber—Interface card is resetting.

Blinking—System is initializing.

L0, L1, L2, L3

Status of link:

On—Link is active.

Off—Link is inactive (disabled).

Blinking— Link is training / Link alarm


What to do next

See the"Connecting Cisco G.SHDSL HWICs to the Network" section for cable information.

Connecting Cisco G.SHDSL HWICs to the Network

Connect Cisco G.SHDSL HWICs as described next:

Cisco HWIC-2SHDSL—Use a standard RJ-11 straight-through cable to establish connection between the HWIC and a network device.

Cisco HWIC-4SHDSL—Use a standard RJ-45 straight-through cable to establish connection between the HWIC and a network device.

Figure 3 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 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 will not work properly.

To connect the Cisco HWIC-4SHDSLwith 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 4 shows how to modify the cable and connect the Cisco HWIC-4SHDSL with a DSLAM that supports four RJ-11 cable connections.

Figure 5 shows how to modify the cable and connect the Cisco HWIC-4SHDSL with a DSLAM that supports two RJ-11 cable connections.

What to Do Next

See the "Configuring Cisco G.SHDSL HWICs" section for information about configuring DSL groups.

Configuring Cisco G.SHDSL HWICs

Configure DSL groups on the Cisco G.SHDSL HWIC, using the Cisco IOS CLI on the router in privileged configuration mode.

Configuring Groups Automatically

Configuring IMA Groups

Configuring M-Pair Groups

Configuring 1-Pair Groups and 2-Pair Groups

Configuring Groups Automatically

Use the dsl-group auto command to automatically assign the Central Office (CO) configuration to an ATM dsl-group on the Customer Premise Equipment (CPE), which has either Cisco HWIC-4SHDSL or HWIC-2SHDSL installed on the router.


Note Automatic configuration is not supported on IMA groups.


Automatic configuration is limited to 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:
1. M-PAIR
2. 4-WIRE
3. 2-WIRE

When the CO is running more than one configuration of the same type, the CPE will select the configuration with link 0.

When the CPE is configured in auto mode, the line coding and annex settings will display either actual or superset of actual coding and annex assigned.

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.


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:
1. M-PAIR
2. 4-WIRE
3. 2-WIRE

When the CO is running more than one configuration of the same type, the CPE will select 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

12.4(15)T

This command was introduced for the Cisco HWIC-4SHDSL and HWIC-2SHDSL running on the Cisco 1841 router, and Cisco 2800 and 3800 series access routers.


Usage Guidelines

This command controls the clock for the IMA group as a whole. If all the links in the group share a clock source, use the ctc keyword. If all the links use different clock sources, use the itc keyword.

When the ctc keyword is set, the clock source ATM interface configuration command for the common link determines clocking for all the links in the group.When the itc keyword is set, the clock source ATM interface configuration command is used under each interface to determine clocking individually.

Because the system automatically chooses a replacement for the common link when it fails, any link in an IMA group can potentially provide the recovered transmit clock. For this reason, even when the common keyword is set with a specific link stipulated by the port value, you should use the ATM interface configuration clock source command to make sure that the clock source is configured correctly on each interface in the IMA group.

Examples

The following example uses the ima group clock-mode command to configure the clock source for an IMA group:

Router(config-controller-dsl-group)# ima group clock-mode ? 

  ctc  Common Transmit Clock configuration
  itc  Independent Transmit Clock configuration
Router(config-controller-dsl-group)# ima group clock-mode ctc ?

This command was introduced for the Cisco HWIC-4SHDSL and HWIC-2SHDSL running on the Cisco 1841 router and on the Cisco 2800 and 3800 series access routers.


Usage Guidelines

Use the dsl-group command to create a DSL group, and then use the shdsl annex command to define the G.991.2 standard for the DSL group.

The shdsl annex coding <16/32 TCPAM> command does not influence the Customer Premise Equipment (CPE) to choose the particular coding 16/32. The command allows you to set the data rate range that is to be supported.

Use the shdsl rate command to set the exact data rate. CPE will automatically choose the TCPAM configuration used by CO/DSLAM.

The show controller shdsl x/y/z command displays the same TCPAM coding information which you provided using the shdsl annex coding <16/32 TCPAM> command. The command does not display the actual coding used for Line Training.

Examples

The following example uses the shdsl annex command to define the annex standard for a 2-Pair DSL group on a Cisco HWIC-4SHDSL:

Router(config-controller-dsl-group)# shdsl annex ?
