Suggest Zyxel VDSL2 modems.

They have been supplying VDSL2 modems for the whole of CHT's Taiwan NGBN for the past 4 years.
This is referring to VDSL2 DSLAM/switches, bridging equipments so don't get mixed up with wireless routers.

Added on April 14, 2011, 6:56 pmGPON technology hass somewhat stalled with an uncertain future.
It does not have a good future direction to upgrade to 2nd generation 10gbps NG-PON as they have yet to settle with any standardization yet for it.

The experts at Google(they're Americans) are also discussing this and whether to choose to implement GPON as they found it more difficult to implement an open network with its complicated switching.They're looking more towards 2nd generation PON technologies and might consider going 10GE-PON.

The Japanese, Koreans, Chinese, Taiwanese have chosen to go the easier and simpler route of sticking purely with ethernet with GE-PON.
They already have 10GEPON now which is already a published standard - IEEE 802.3av

Malaysia, Singapore, India, Australia have all been sold to American's smart marketing of adopting GPON.
Now TM is stucked with GPON while having to pay more for it.

On average, GPON equipments cost more, requires higher transmit power and is more more difficult to maintain.

Added on April 14, 2011, 7:01 pmTM has banned ALU from tendering for future projects recently after the corruption scandal case.

As we know, they were the ones who supplied the GPON equipment in Putrajaya and Cyberjaya. Another white elephant project which flushed money right down the drain.

1. Business men tactics for advertising and cronies get away all the time.
Louder volume to get your attention.

2. If the old telephone is important to you, do not cancel your service and retain it.
Unifi's VoIP service is inferior to POTs. It gets cut off in the event of blackout, does not allow conventional fax, dial out and retaining of your old number.
If the telephone is important to you where you need to make emergency or receive urgent calls, PAY for your basic telephone service.

You should have save the money to buy high quality phone wiring and extend the wiring yourself. Only leave the wiring to the termination box untouched for TM to hook it up.

Of course la. This is to help the 1 race to make a living so that they won't end up jobless and commit crimes.

The whole HSBB project and Unifi was meant to provide job openings and opportunities to certain people for the country.
From the main contractor to the subcontrators and site installs.

VDSL2 Vs FTTH By ITU-T

If power cut?

PPS the bandwidth eater..

FUH.. that day at McD saw a girl sat down and turn on her laptop.Straight away launch PPS to watch drama...

Looks like wimminz are also big consumers of bandwidth today.

Most recently GPON news have came to a standstill. It's unknown what will be of Unifi's FTTH network fate will be in the next few years.

1st quarter report for telecom wired news mentioned that both DSL and PON technologies saw a market decline.

While passive optical networks sales are still going strong as reported by both Huawei and ZTE, they are fueled by demands mostly in China's domestic market as infrastructures are still new over there. In China, the telcos are government owned and they keep their national interest by buying their own products to keep their local companies alive.

Even so, all the far east asian countries China, Japan and South Korea favors EPON(GEPON) over GPON which TM uses. The decision is due to its cost effectiveness and less complicated ethernet transport.

Here's the summary of the report:

http://www.eeherald.com/section/news/nws201105257.html

VDSL2 could operate in 3 different modes.

The first being fiber to the building's basement(FTTB). This allows upto 100mbps in replacement of ethernet cables but uses a full wide 30MHz spectrum.
When VDSL2 is deployed with this method, usually POTs are disabled meaning it becomes a full digital data line.Requires very short distances.

Then like you said fiber to the cabinet(FTTC) which they install in every few row of houses along the road. This allows upto 50mbps/10mbps in theoretical but BT chose to offer 40mbps/10mbps upload with it. This uses the 17a/b profile which is similarly associated with ADSL's Annex A/B modulation.

The 3rd option would be VDSL2 from exchange. Premises within 1.5-2km will only benefit from this as they'll be able to access higher speed packages upto 20mbps if they live just around 1km away. This method is rarely used because the benefits are substantial.

In summary VDSL2 have 3 options:

1)FTTB - Taiwan, Japan, HK, Finland, Sweden
2)FTTC - UK, Germany, USA, Australia, NZ, Europe, Thailand, Canada
3)Exchange based.
