Chapter 18 ADSL Service Application

This chapter includes the following:

Overview

Configuration Procedure

Configuration Example

18.1 Overview

ADSL is a technology using existing telephone twisted pairs to provide asymmetric

upstream and downstream rates. ADSL is very suitable for the current application

features of the Internet.

The ADSL has two standards: ADSL and ADSL2+. Compared with ADSL, ADSL2+ has

the following features:

ADSL2+ provides higher downstream and upstream rates than ADSL.

The maximum downstream rate of the ADSL can reach 8160 kbit/s, while that of

the ADSL2+ can reach 24 Mbit/s.

The maximum upstream rate of the ADSL can reach 896 kbit/s, while that of the

ADSL2+ can reach 1.2 Mbit/s.

ADSL2+ provides the power management, which can reduce the running power

consumption.

ADSL2+ supports longer transmission distance than ADSL. The distance

supported by ADSL is less than 5 km, while ADSL2+ 6 km.

More stable running and spectrum compatibility.

More adaptable for line parameter changes.

Shorter training process.

Faster restoration of connection.

The UA5000 has two kinds of cards to support the two applications:

The ADL/CSL card provides 16-port ADSL access service.

The ADM/CSMB card supports 16-port ADSL2+ access service.

The ADL, ADM, ADRB cards provides only the ADSL service. The CSL and CSMB

cards provide ADSL and POTS services.

The configuration procedures for ADSL and ADSL2+ services are the same. This

chapter takes the configurations for ADL card as example.

Note:

This chapter describes the configuring procedure with an example. For other details

such as parameters and notes, refer to the chapter “Configuring Ports”.

The CSL card is integrated with the ADSL and POTS ports. The ADSL port

configuration is the same as other cards. For the configuration of the POTS port,

refer to UA5000 Operation Manual-PVM Volume.

In this example, the networking details are as follows.

The ADSL subscriber connects to port 0 of the ADL card through a modem at RFC

1483B mode. The upstream bandwidth is 512 kbit/s, and the downstream

bandwidth is 1 Mbit/s.

The ATU-C power-off alarm threshold is 60s. Report the failure of line initialization.

Report the alarm if the re-training count exceeds 3 times.

The IPM card is connected to the upstream IP network through the FE port.

Note:

To control the ADSL data rate, you can use port-based rate or traffic entry-based rate

restriction.

Port-based rate restriction is to control the data rate by setting maximum upstream

and downstream rates of the line configuration profile.

Traffic entry-based rate restriction is to control the data rate of the virtual service

port connecting the ADSL port by referencing a specified traffic entry.

When both restriction modes are used, the bandwidth assigned to the user is the

smaller one.

18.3.2 Configuration Procedure

I. Adding an ADL card

Plug an ADL card into an available line card slot (slot 7 in this example) of the UA5000

frame.

II. Confirming the ADL card

To confirm the ADL card, do as follows:

huawei(config)#board confirm

{ frameid[/slotid] }:0/7

III. Configuring the ADSL line profile

The UA5000 has an embedded ADSL line profile, with the profile ID of 1, which can be

used for the common ADSL service.

If the port rate is limited based on the traffic entry, you can use the default ADSL line

profile 1 directly. In this configuration example, the upstream bandwidth is set as 512

kbit/s, and the downstream bandwidth as 1 Mbit/s.

If the port rate is limited based on the traffic entry, you must configure the line profile

and set the maximum upstream and downstream rates for the traffic control. In this

case, set the port rate in the traffic entry to the maximum value for controlling the rate of

the virtual port. In this configuration example, the upstream bandwidth is set as 512

kbit/s, and the downstream bandwidth as 1 Mbit/s.

To configure the ADSL line profile, do as follows:

huawei(config-if-adsl-0/10)#adsl line-profile add

{ |profile-index }:

IV. Configuring the ADSL alarm profile

You can configure a specific alarm profile for the ADSL service. For example, there are

following requirements:

The threshold of the local end power-off is 60s.

The line initialization failure will be reported.

Alarms will be reported after the link re-training failure reaches three times.

To configure an alarm profile for the above requirements, do as follows:

huawei(config)#adsl alarm-profile add

{ |profile-index }:

Command:

adsl alarm-profile add

Start adding profile

Press 'Q' to quit the current configuration and new configuration will be

neglected

Add profile 2 successfully

V. Binding the ADSL alarm profile

After the ADSL alarm profile is configured, bundle it to the corresponding port to make

the alarm profile effective. By default, all ports are bundled with the alarm profile 1.

To bind the ADSL alarm profile, do as follows:

huawei(config-if-adsl-0/3)#alarm-config 0 2

VI. Confirming that the ADSL port is activated

By default, the UA5000 activates the ADSL port automatically. If the default line profile

is used, query the port state. If it is "activated”, it means the ADSL port is activated.

To use a new line profile, deactivate the ADSL port and then activate the port with the

new profile.

huawei(config)#interface adsl 0/7

huawei(config-if-adsl-0/7)#deactivate 0

huawei(config-if-adsl-0/7)#activate

{ PortID|all }:0

{ |profile-index|profile-name }:profile-index

{ profile-index }:2

To query the port state, use the display port state command.

huawei(config-if-adsl-0/7)#display port state 0

-----------------------------------------------------

Port Status Line_Profile Alm_Profile

-----------------------------------------------------

0 Activated 2 2

-----------------------------------------------------

VII. Configuring traffic parameters

If the default traffic entries do not meet your requirements, configure a traffic entry as

follows:

Set the upstream traffic parameters.

huawei(config-if-adsl-0/7)#quit

huawei(config)#traffic table atm srvcategory

VIII. Configuring the upstream port and VLAN

1) Configure the upstream port

Refer to the chapter “Configuring Ports” to configure the physical attributes of

Ethernet interface of the IPM card. Suppose the peer end is a 100 Mbit/s port, and

works in full duplex mode.

huawei(config)#interface ipm 0/3

huawei(config-if-ipm-0/3)#speed 0 100

huawei(config-if-ipm-0/3)#flow-control

{ portid|all }:0

huawei(config-if-ipm-0/3)#display port state 0

The port is active

Native VLAN ID is 1

Ethernet port is offline

Ethernet port is full duplex

Ethernet port rate is 100M

Ethernet port supports flow control

Line-adaptive function of the ethernet port is auto-negotiation

2) Configure a VLAN.

The xDSL access service supports two types of VLANs: Smart VLAN and MUX

VLAN. For details about these two types of VLANs, refer to the chapter

“Configuring VLAN”.

This example adds a Smart VLAN, with VLAN ID as 2.

huawei(config)#vlan

{ vlanid|attrib }:2

{ vlantype|to }:smart

3) Add the upstream port of the IPM card to the VLAN

huawei(config)#port vlan

{ vlanid }:2

{ frame/slot|to }:0/3

{ portlist }:0

IX. Configuring the virtual port

Configure a virtual service port for the ADSL access service. For details about the

virtual service port, see the chapter “Configuring the Virtual Ports”.


11/12



18-10

huawei(config)#service-port

{ vlan }:vlan

{ vlan }:2 //Identical with the upper layer equipment

{ ima|vdsl|lan|atm|e3/ds3|adsl|shdsl }:adsl

{ frame/slot/port }:0/7/0

{ rx-cttr|vpi }:vpi

{ vpi }:0 //Identical with the Modem side setting

{ rx-cttr|vci }:vci

{ vci }:35 //Identical with the Modem side setting

{ rx-cttr }:rx-cttr

{ rx-index }:8 //Use the traffic entry-based rate restriction.

Input the index of the traffic entry.

{ tx-cttr }:tx-cttr

{ tx-index }:7 //Reference the traffic entry that meets your traffic

requirements.

Add service virtual port successfully!

X. Querying the line parameters of the port after activation

After the configuration of the peer end completes, you can query the line parameters of

the ADSL port.

huawei(config)#interface adsl 0/7

huawei(config-if-adsl-0/7)#display line operation 0

XI. Configuring the relevant equipment and testing services

Configure remote modem and PC as follows based on different network access modes.

After configuring the UA5000 upper layer equipment, you can start to test the service.

1) PPPoE network access mode

Set modem to work in RFC 1483 bridge mode.

Set VPI and VCI of WAN port of the modem. These values must be consistent with

those of the PVC configured before.

Install PPPoE dial-up software on the PC and set user account and password.

IPoE network access mode

Set modem to work in RFC 1483 bridge mode.



Configure IP address of the PC. This IP address and the IP address of user-side

interface of the upper layer BAS must be in the same network segment.

2) PPPoA network access mode

Set modem to work in PPPoA mode.




12/12



18-11

Set authentication mode, which must be consistent with that configured on the

BAS.

Set user account and password.

Configure the IP address of the PC. This IP address and the IP address of LANport of the modem must be in the same network segment.

3) IPoA network access mode

Set modem to work in RFC 1483R mode.



Configure IP address of the WAN port of the modem (bind this IP address with the

corresponding PVC when configuring the user on the BAS) and the peer end IP

address (IP address of the user-side interface on the BAS). Set this peer end IP

address as default gateway.

Configure the IP address of the PC. This IP address and the IP address of LAN

port of the modem must be in the same network segment.

XII. Querying port cell statistics and real-time data RX and TX rates

After the configuration, the user can access the Internet. Then, you can query the

real-time port cell statistics.

huawei(config-if-adsl-0/7)# quit

huawei(config)#display traffic 0/7/0

XIII. Saving the data

huawei(config)#save
