DSL - VDSL-based Service Sets

DSL – VDSL-based Service Sets

VDSL offers a variety of simultaneous services, which are not possible otherwise. This opens the possibility for service providers to offer a new base for your subscription and multimedia services. Telco providers offering telephony and data services can now expand their business by offering comprehensive services and a host of video-centric applications. This enables the telecom companies to compete with television operators by effective invasive cable.

The original charter for ADSL was to provide a full range of broadband services for residential consumers, so why the need for VDSL? The reality is that ADSL is an Internet technology only.

The following table illustrates that, in the end, ADSL is limited in its ability to provide a full range of broadband services. VDSL, on the other hand, is well suited to provide these services today and tomorrow
