ADSL2+ Migration Guide LLU ADSL2+ to Cerberus ADSL2+ (WS)

Introduction

The scope of this guide is to help you, the customer, understand the process for migrating your ADSL2+ service from LLU ADSL2+ to Cerberus ADSL2+ (WS).

Naming Conventions

The products previously known as Cerberus ADSL2+ are now known as LLU ADSL2+. Our new ADSL2+  products are now sold under the name Cerberus ADSL2+. You may also see the new Cerberus ADSL2+ services shown as Cerberus ADSL2+ (WS).

Step 1: Preparing for the move

The technology behind LLU ADSL2+ service is different from Cerberus ADSL2+ (WS) in several ways:

  • Cerberus ADSL2+ (WS) uses PPPoA (LLU ADSL2+ uses IPoA) and also supports PPPoE
  • Cerberus ADSL2+ (WS) uses routing for Multiple IP addresses (LLU ADSL2+ uses bridging).
  • Cerberus ADSL2+ (WS) uses MultilinkPPP for bonding (LLU ADSL2+ uses G.998.1).
  • Cerberus ADSL2+ (WS) requires a username/password login for each line (LLU ADSL2+ implements access control on the DSLAM port)
  • Cerberus ADSL2+ (WS) IP addresses are not fixed to a particular geographic area (LLU ADSL2+ IP addresses were specific to exchanges served by a given aggregation point).

The differences in the two technologies provide several advantages for you, the customer:

  • The PPPoA standard is the most common worldwide and allows greatest choice of Customer Premises Equipment (eg router, modem).
  • Multilink PPP does not require tie-pair changes or port moves at the exchange to accomplish bonding.
  • Multilink PPP breaks the two-line bonding limit. The technology does not place a limit on bonding. Routers are currently available that allow bonding of up to 8 lines.
  • PPP Logins are interchangeable (within same realm) so customers with multiple lines can test another site’s configuration on their own line before installation (please note each login may only be used in one location at a time, but Cerberus do not need to be informed if you switch location for test or failover purposes).
  • IP addresses provided to Cerberus ADSL2+ (WS) customers are interchangeable across different connections of the same type regardless of geography.
  • Routing rather than bridging to provide blocks of IP addresses allows for easier use of third party firewalls and other network equipment.

Prior to choosing to migrate your line from LLU ADSL2+ to Cerberus ADSL2+ (WS) you need to consider several things:

  • You should ensure that your router or modem is capable of connecting to PPPoA services. If you have bought or leased a Technicolor (formerly known as Alcatel or Thomson) Speedtouch branded router from Cerberus then your router hardware is capable of supporting IPoA but you will need to load new firmware onto the router to enable PPPoA. Cerberus will provide the firmware and updater tools for download, free of charge, on its website. Please note that the updater software requires Microsoft Windows. For customers who wish to migrate from LLU ADSL2+ to Cerberus ADSL2+ (WS) but who are unable to update the firmware in their router Cerberus will swap out the unit with a pre-updated refurbished unit. You will just pay for delivery of the router to you and return of your unit back to us.
  • If you had one or more fixed IP addresses assigned to your LLU ADSL2+ connection then you should be aware that these IP addresses will change. It is not possible to keep your current IP address(es) when changing. Customers with dynamic IP addresses should be aware that the dynamic IP pool will also change. Fixed IP customers will be provided with their new range in advance before losing the old one and have a reasonable period of time to change over, more information can be found later in this document.
  • When routing any more than 1 static IP, you will lose 2 IP addresses from any block of IP addresses (one is used for the network and one for the broadcast). You may need to request a larger IP address block as a result. For instance from a block of 8 IP addresses 1 is used for network, 1 for broadcast, 1 for the router, leaving 5 IP addresses available for use by other devices. You may wish to consider PPPoE which is the closest equivalent of the Single IP bridged mode that you may be used to. See Appendix A for information on PPPoE Passthrough.
  • Bonded customers wishing to migrate from LLU Bonded ADSL2+ to Cerberus X2 Bonded ADSL2+ will need to swap their Comtrend Nexuslink router for an alternative. At this time we are unable to supply alternative firmware for the Comtrend Nexuslink router, although this is being worked on.
  • You will experience a short period of downtime while you upgrade the firmware on your router to support PPPoA (typically this takes about 5 minutes); and reconfigure the router to  reconnect as PPPoA (again, typically this takes about 5 minutes). The date and time when these occur, and the length of the outage, are entirely under your control.

Step 2: Plan your migration and understand the process

When you schedule your migration from Cerberus, we will begin by changing the configuration of the DSLAM port that your line connects to. The DSLAM is the piece of equipment at the other end of your telephone line at the local telephone exchange.

Under LLU ADSL2+ the DSLAM port is configured to allow only IPoA connections. During the first part of your migration to Cerberus ADSL2+ (WS) we will reconfigure your DSLAM port to allow use of both your existing IPoA configuration and your new PPPoA configuration.  You will then be supplied with a PPPoA login, password and any fixed IP addresses (if you have purchased this option).

During the migration period you can reconfigure your equipment at a time of your choice to use the new details. If you have any problems with the new login details, then so long as you are still within the migration period you may temporarily switch back to the old IPoA configuration. Once you complete the migration we will permanently remove your ability to connect via IPoA, usually within 5-7 days.

Once the migration is complete your billing will be adjusted and you will be charged for the new Cerberus ADSL2+ (WS) service. You will receive a pro-rata credit against any pre-paid time remaining on the old LLU ADSL2+ service.

Step 3: Upgrade the router firmware

If you have a Cerberus supplied Speedtouch 780WL, 585v6 or 585v7 router then you will need to upgrade your firmware prior to reconfiguring your router.  If you have a different router and you have verified that the router supports PPPoA then you can ignore this section and proceed to Step 4.

These instructions are written using the Thomson Technicolor Speedtouch 585v7 as an example. The process is very similar for the 585v6 and 780WL so we have not duplicated the instructions, but if you require any clarification please contact our support team.

Please be aware that this upgrade will reset the router back to factory defaults. You should make a note of any custom settings (for instance Wireless Network Name, Wireless Key, Port Forwarding etc) before you proceed and be ready to re-enter these afterwards.

Please also note that once you perform this upgrade the router will no longer be able to connect to the old service unless you revert the router back to its old firmware. You should only start this upgrade if you are ready to proceed with reconfiguration immediately after upgrading your firmware.

You can download the software needed from us using these links:

To convert a Speedtouch 780WL from LLU firmware back to Retail firmware for use with our Cerberus ADSL2+ (WS) service please download this file.

To convert a Speedtouch 585v6 from LLU firmware back to Retail firmware for use with our Cerberus ADSL2+ (WS) service please download this file.

To convert a Speedtouch 585v7 from LLU firmware back to Retail firmware for use with our Cerberus ADSL2+ (WS) service please download this file.

Please ensure that you download the correct version.

From your computer launch the Upgrade wizard (TG585v7 82xx.exe or other appropriate for your router) that you have downloaded. Before starting please ensure that you have performed the following:

-          Connect the Thomson router to computer using the Ethernet cable (Cat5).

-          Switch on the router (check the power light is displaying a green light).

This will search for the connected device (Thomson router) and flash the firmware. Once the device is detected you will see the progress bar move till it reaches 100%.

Once completed click on the Quit button and then proceed by logging on to the router’s homepage using an Internet Browser on IP address http://192.168.1.254 this will enable you to proceed with the next stage: reconfiguring your router for the new connection.

Troubleshooting

If you experience any problem in getting the upgrade tool to detect your router, please perform the following troubleshooting steps:

  • Check if router is powered on and check the power light is displaying a green light.
  • Connect Ethernet cable and check to see if the port you are connected to lit green.
  • Check the network card (LAN) settings on your machine to see if it’s set to obtain an IP address automatically.
  • Reset the router back to factory default (By sticking a pin in the reset hole).
  • Disable any firewall or antivirus you may have running on your machine.
  • Check to see that you are not connected to any other Thomson routers on your network.

Step 4: Reconfigure your Router

You will have been supplied a username and password for your new service. If you have taken a fixed IP address or addresses then you will be supplied these at the same time. You should ensure that you have these ready before you begin.

If you have a Cerberus supplied Speedtouch router you should follow these instructions:

For users with single fixed IP Address

1. Begin by clicking Next

2. Select Data (Default). Click Next

3. VPI/VCI 0.38 – PPPoA (UK Default), Enter Username and Password. Click Next

4. Configure the wireless SSID and Security. Click Next

5. Enter and confirm a new router password. Click Next

6. Confirm all the settings details you have entered. Click Start to complete.


For users with a routed block of IP Addresses

1. Select Data (Custom) Click Next

2. VPI/VCI 0.38 – PPPoA (UK Default), Enter Username and Password Click Next

3. Select the type of IP connection you Require. Click Next

4. Enter your WAN IP details. Click Next


5. Set the DHCP range you require or disable DHCP if not required by removing the tick from Enable DHCP. Click Next

6. By default the firewall is disabled, you can enable firewall protection if required by ticking the Enable Firewall Protection button. Click Next

7. Configure the wireless SSID and Security. Click Next

8. Enter and confirm a new router password. Click Next

9. Confirm all the settings details you have entered. Click Start to complete.

For users of other routers:

If you have a different router then you should reconfigure the router to use the following settings:

  • Protocol / Encapsulation: PPPoA / VCMUX
  • VPI/ VCI: 0/38
  • Mode: ADSL2+ or automatic ( this is unchanged )
  • Please note that support for Annex A and Annex M (increased upload) is unchanged.
  • DNS Servers: 46.37.32.22 and 46.37.33.22 (these are unchanged).

You should be asked for your username and password. If you are not asked then please check your Protocol settings.

Customers with a single fixed IP do not need to enter this fixed IP address. Customers with a routed block should enter their router IP address and subnet mask.

If you have any difficulty during the reconfiguration you should contact our support team on 0845 257 1333, or This e-mail address is being protected from spambots. You need JavaScript enabled to view it. . Cerberus Support operates 24 hours a day.

Step 5: Confirm successful completion to Cerberus

When you are happy that you have successfully connected your service via Cerberus ADSL2+ (WS) you must confirm the completion to Cerberus by email to This e-mail address is being protected from spambots. You need JavaScript enabled to view it. , or using our web based portal NetCONNECT .

Once you confirm completion we will formerly move the circuit administratively from the old product type to the new product type. We will remove the old details and reconfigure your port so you will no longer be able to log in with IPoA.  This reconfiguration will not cause downtime to the PPPoA service. We will also adjust your billing so that you receive a pro-rata refund for the old service, and new billing for the new service.

It is very important that you contact us to confirm that you have successfully connected. If we do not hear from you you will continue to be billed for the old product. If we do not hear from you within one month we will assume you do not want to migrate and will remove the PPPoA login ability .

Appendix A:  Using A Thomson/Technicolor Speedtouch & common equipment to do PPPoE.

As mentioned earlier: when routing any more than 1 static IP, you will lose 2 IP addresses from any block of IP addresses (one is used for the network and one for the broadcast). To avoid having to request a larger IP address block you should consider PPPoE.

When using PPPoE  the PPP session is not initiated by the router, instead it is initiated by a device connected to the router using wired or wireless Ethernet. So if you previously took a service with us that had only one IP address, but you exposed this to a firewall or server that you had connected, using bridging, you can accomplish the same result by configuring your firewall or server to use PPPoE.

In these examples we will show you how to configure a Thomson Technicolor Speedtouch 585v7 to put it into pass-through mode.  However it is a similar process for other Speedtouch variants. If In doubt please contact our support team.

We will also show you how to configure Windows to initiate a PPPoE session, which is then passed through the speedtouch and onto the network.  We also show you a common Draytek Vigor router being used as a simple firewall in line with the speedtouch.  You do not have to use Windows or a Draytek Vigor. These are simply intended as examples of a Modern Operating System and a Firewall.  Windows XP, Vista, 7,  Windows Server, Mac OS X, Linux and others all support PPPoE, as do Firewalls from Fortinet, Cisco, Juniper and others.

Setup PPPoE Passthrough on the Speedtouch

1. Begin by clicking Next

2. Select Bridge. Click Next

3. VPI/VCI 0.38  (UK Default). Click Next

4. Disable DHCP Server. Click Next

5. Enter and confirm a new router password. Click Next

6.Confirm all the settings details you have entered. Click Start to complete

7. Your router has now been configured to operate as a modem only.

Setup PPPoE on Microsoft Windows 7:

Using Windows 7 (Set Up Connection) configure a PPPoE connection.

1.Choose “Connect to the Internet”  and Click Next

2.If you see this screen Choose “Set up a new connection anyway”. Click Next

3.Select “No, create a new connection”. Click Next

4.Click on the Broadband (PPPoE) option.

5. In the section you will need to enter the username and password that was provided to you by Cerberus.

Now test the connection by connecting your router to the computer using the Ethernet connection (Cat5) that you have configured the connection on.


Setup PPPoE on a Draytrek Vigor

To setup a Draytrek router using PPPoE you will need to firstly ensure that the Draytek router model you are using has an Ethernet WAN port (Such as the Draytrak 2820, 2930 etc).

Begin by connecting the modem to the WAN port of the Draytek router using an Ethernet cable (Cat5).

1. Click on the WAN > Internet Access > Select the Ethernet WAN port

2. Select PPPoE > Enable the profile

3. Enter the ISP’s Username and Password (This is the username and password that was provide to you on the activation of your service)

4. WAN Connection Detection – ARP Detect

5. PPP Authentication –  CHAP

6. IP Address – No (Dynamic IP)

7. Default MAC Address

Apply the settings by clicking on OK and test the connection.
