Yeap

Hhmm. Guys. I'd like to confirm 1 thing on this.

1) Maxis uses 2 diff Vlan ID for HSI
      Those using TM Modem (Vlan Tag is 621)
      Those using Modem provided by Maxis (Vlan Tag is 11) [The following setting is based on this]
Please refer to Attachment. This is a Thomson Config file i've downloaded for backup.
[attachmentid=3007675]

Also I'd like to share my experience using TPLink 1043ND router with Huawei Echolife HG8240 & Thomson (mainly for VoIP)

All Vlan Tagging are done on the TPlink router hence there is no need to configure the Echolife HG8240. *I'd like to point out that not everyone is done in this manner, hence please check before following the guide.

This is how my wiring setup
[attachmentid=3007694]
This is how i've configure the Switch & Vlan Tagging Setting (Under Network --> Switch)
[attachmentid=3007695]
I also like to highlight that Port 1 in the image is WAN port, Port 2 is Eth 1 ... Port 5 is Eth 4
For my case i used Eth 4 hence is port 5. Take note on the Vlan ID 1 under Port 5 change it to off. Add Vlan ID 11 and change Port 5 to "Tagged" & CPU to "Tagged"

then save & apply

This is the WAN Setting (Under Network -- > Interface --> WAN)
[attachmentid=3007697]
Change the setting to VLAN Interface eth0.11

then save & apply

Then under General Setup  (Under Network -- > Interface --> WAN)
Change protocol to PPPOE
enter username xxxxx@home.maxis.com.my or xxxxx@public.maxis.com.my
password is usually the xxxxx1 (where xxxxx represents the 5 digit before @home.maxis)

Save & apply..
You are done

surely work?

does it can apply other model ?
