Digi TransPort VDSL Configuration for BT Infinity

British Telecom Infinity VDSL Lines require specific settings in order to operate properly with a Digi TransPort WR44 Router.

You can find more details about BT Infinity on their web site : www.bt.com/broadband
 

Web Interface Configuration:

VDSL can run in bridged Ethernet mode or PPPoE.  It is likely that PPPoE mode will be the most common. In this article, PPPoE mode will be described.

Please note: Digi TransPort Routers with DSL comes pre-configured for standard DSL lines. This article describes the changes needed to use a BT Infinity VDSL line.

Chose an un-used Ethernet interface as the WAN interface to link with VDSL, so preferably a logical interface, e.g. ETH 12 and set it to DHCP.

Configuration - Network > Interfaces > Ethernet > Logical Ethernet Interfaces > ETH 12

User-added image

- Get an IP Address automatically using DHCP

Click Apply


Link the DSL interface with Ethernet 12

Configuration - Network > Interfaces > DSL

User-added image
 

- Check Enable DSL
- Chose 12 in the "Link VDSL interface with Ethernet"
- Make sure "Enable this PVC" is UNCHECKED.
- Click Apply

Configure PPP 3 to use PPPoE and Ethernet 12

Configuration - Network > Interfaces > Advanced > PPP 0-0 > PPP 3

User-added image

- Select PPPoE under "This interface will use"
- enter the MAC number and Interface number in the next field. To confirm this information :

 

NOTE, THE CORRECT MAC ADDRESS MUST BE DETERMINED AND DEFINED.

Assuming Eth 12 was selected earlier, check the MAC address in use by Eth 12 via the command line which is accessible from the web interface under Administration - Execute a command


eth 12 status
Activation Status:      Inactive
Connection Status:      Connected
Physical Port:          VDSL
MAC:                    00 04 2D E3 AE B4
IP Address:             0.0.0.0
Mask:                   0.0.0.0
Gateway:                0.0.0.0
OK


Note the MAC address in use (above) and cross reference this with the 'hw' output (below) to determine which MAC address Eth 12 is using:


hw

Serial Number: 241332
HW Rev: 5203a
MAC 0: 00042d03aeb4
MAC 1: 00042df3aeb4
MAC 2: 00042de3aeb4
MAC 3: 00042dd3aeb4
MAC 4: 00042dc3aeb4
MAC 5: 000000000000
MAC 6: 000000000000
Model: TransPort WR44v2
Part#: WR44v2-U800-DE2-XX
RAM: 64 MB
FPGA Rev: 1.0
MSP430 Rev: 1.1
WWAN supply: 1.931 V
OK

It can be seen above that Eth 12 is using MAC 2. The field should now be populated with 212.

In this test, the following username/password is used. Please note that these might changed based on the contract or per customers. Please check with BT for the correct username/password to use.
- username: bthomehub@btbroadband.com
- password: bt


Configuration - Network > Interfaces > Advanced > PPP 0-0 > PPP 3 > PPP Negotiation

User-added image


- Desired local ACCM: 0xffffffff
- Desired local MRU: 1492
- Uncheck ALL Request options.
- Desired remote ACCM: 0xffffffff
- Desired remote MRU: 1492
- Remote ACFC: Deny
- Remote PFC: Deny
- Click Apply

Configure Ethernet 12 VLAN

BT Infinity requires a VLAN ID on the PPPoE packets to be set to 101.

Configuration - Network > Interfaces > Ethernet > VLANs

User-added image


- Check ETH 12

Scroll down to the VLANs configuration

User-added image

- Set VLAN ID to: 101
- Set Ethernet Interface to: 12
- Click Add

It should now look like this:
