Altyapı sağlayıcısı TT, ADSL hizmetinde olduğu gibi VDSL2 servisini de toptan olarak satacak. Ardından da başta TT Net olmak üzere diğer şirketler bu servisi son kullanıcıya ulaştıracak.

İlk etapta 30 megabit olan hız seviyesi, 70 megabite kadar çıkacak. Şirketin 2008 sonu hedefi bu servisi 250 bin kullanıcıya ulaştırmak. Bunun için ciddi altyapı yatırımı yapan firma, yurtdışı çıkış hatlarını da kuvvetlendirmek için çalışma başlattı. Bu kapsamda New York, Londra ve Paris’te POP noktaları kurulacak. Bu sayede gerek duyulduğunda buralardan da hizmet alınmış olacak.

VDSL2 aynen ADSL’de olduğu gibi telefon hattı kullanılarak ve hat meşgul edilmeden kullanılıyor. Sadece modemlerin bu teknolojiye uyumlu olması gerekiyor.

VDSL2 sayesinde, kullanıcılar Triple Play denilen ses, görüntü, veri, yüksek çözünürlüklü televizyon (HDTV) ve interaktif oyunlardan da yararlanabiliyor.
