Configuring the HWIC-1VDSL

---

First Published: March 17, 2010

This document describes how to configure the HWIC-1VDSL. The HWIC-1VDSL can be installed on the Cisco Integrated Services Routers Generation 2 (ISR G2) family platforms and can deploy services such as voice, video, and data. It supports the following features:

•Very-high-data-rate digital subscriber line 2 (VDSL2) profiles: 8a, 8b, 8c, 8d, 12a, 12b, and 17a

•ITU-T G.993.2 protocol

•Flash Firmware Upgrade

•WAN Ethernet Support in VDSL Packet Transfer Mode (PTM) support, using 64/65 802.3ah format

•IEEE802.1q support: VLAN tagged frames supported in Ethernet mode of VDSL

HWIC-1VDSL is the SKU for the single port HWIC-1VDSL.

Prerequisites for the HWIC-1VDSL

This section lists the prerequisites for configuring the HWIC-1VDSL.

•Ensure that you have the appropriate Cisco access router to serve as the host router. The following Cisco access routers support HWIC-1VDSL.

–Cisco 1900 series ISRs

–Cisco 2900 series ISRs

–Cisco 3900 series ISRs

•Use the show version command to ensure that the router is running Cisco IOS Release 15.0(1)M1 or later.

---

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

---

•Install the HWIC-1VDSL on the router, using the directions provided in Installing Cisco Interface Cards in Cisco Access Routers and Cisco Network Modules and Interface Cards Regulatory Compliance and Safety Information.

Restrictions for the HWIC-1VDSL

Online insertion and removal is not supported for HWIC-1VDSL.

Overview of the HWIC-1VDSL

The HWIC-1VDSL is used on the Cisco ISR G2 platforms to provide VDSL over POTs WAN connectivity. It can be installed on Cisco ISR G2 platforms, and the external RJ-11 port is connected to a DSL line coming from VDSL2 supported DSLAM.

To configure the HWIC-1VDSL, you should understand the following concepts:

•VDSL2

•Ethernet over VDSL (PTM) mode

Feature History

Release	Modification
15.0(1)M1	The feature was introduced.

Faceplate

Figure 1 shows the faceplate for the HWIC-1VDSL.

LEDs

Table 1 lists the LEDs and describes their functionality and different states. The LEDs provide a visual indication of your available services.

Table 1 Cisco HWIC-1VDSL LED Descriptions

LED Label	LED Color	LED Status	Description
EN	Green	On	The host platform has successfully detected the HWIC and FPGA firmware has been successfully downloaded.
		Off	HWIC detection failure or FPGA firmware download failure.
CD	Green	Blinking	VDSL firmware is being downloaded or VDSL line is in training mode (Layer 1 handshake/bit rate negotiation phase).
	Green	On	Successful handshake negotiation with DSLAM has occurred and Layer 1 Link has been established (showtime).
LP1	Yellow	On	HWIC is in Loopback mode. Loopback occurs at HWIC MAC interface. (Local Loopback).
		Off	Not in Loopback Mode.

1 Loopback is used for debugging purposes only.

Configuring the HWIC-1VDSL

This section describes how to configure your HWIC-1VDSL. There is no need to configure any VDSL2 controller parameters from the CPE side. By default the controller is up; however you must configure the PTM interface manually as shown in Step 2 to Step 7 below.

---

Note Any specific VDSL2 settings should be set on the DSLAM side.

---

SUMMARY STEPS

1. enable

2. configure terminal

3. interface type slot/subslot/port number

4. ip address ip-address mask

5. shutdown

6. no shutdown

7. exit

DETAILED STEPS

	Command or Action	Purpose
Step 1	enable Example: Router> enable	Enables privileged EXEC mode. •Enter your password if prompted.
Step 2	configure terminal Example: Router# configure terminal	Enters global configuration mode.
Step 3	interface type slot/subslot/port number Example: Router(config)# interface ethernet 0/3/0	Enters the configuration mode for Ethernet Layer 2 transport on the VDSL WAN interface on the router.
Step 4	ip address ip-address mask Example: Router(config-if)# ip address 192.168.12.2 255.255.255.0	Sets the IP address and subnet mask for the interface.
Step 5	shutdown Example: Router(config-if)# shutdown	Disables the interface, changing its state from administratively up to administratively down.
Step 6	no shutdown Example: Router(config-if)# no shutdown	Enables the interface, changing its state from administratively down to administratively up.
Step 7	exit Example: Router(config-if)# exit Router(config)#	Exits configuration mode and returns to global configuration mode.

Troubleshooting Tips

If you experience trouble with the VDSL2 connection, verify the following:

•The VDSL line is connected and using the two center pins of the line (pins 2 and 3 of a 4-wire RJ-11 plug or pins 3 and 4 of a 6-wire RJ-11 plug). For more information on the VDSL2 connection, see the hardware guide for your router.

•The VDSL2 LED CD light is on. If it is not on, the router may not be connected to the DSL access multiplexer (DSLAM). For more information on the VDSL2 LED, see the hardware installation guide specific for your router.

•The DSLAM supports the VDSL2 signaling protocol.

Use the show controller vdsl slot/subslot/port number command in privileged EXEC mode to view a VDSL2 configuration. The debug vdsl slot/subslot/port number daemon state command can be used to enable the debug messages that print the state transition of VDSL2 training.

You can reload or upgrade the firmware file into the VDSL chipset without upgrading your Cisco IOS image. To use a DSL firmware other than the embedded one, use the firmware filename command in controller configuration mode. Use the no form of the command to revert back to the embedded firmware. Next, enter the shutdown and no shutdown commands on the VDSL2 controller. The new firmware is downloaded and the VDSL2 line starts training up.

If the command is not present or the named firmware file is corrupt or not available, the default firmware file flash:vdsl.bin is checked to be present and not corrupt. The firmware in this file is then downloaded to the modem chipset.
