The importance of Broadband IP Access has been demonstrated by the year-after-year increase of new and innovative Internet, Voice, and Video applications. The adoption of IP gives service providers much more flexibility and efficiency than traditional networks comprised of various technologies such as frame relay, ATM, and TDM.

VDSL2, ADSL2 and ADSL2+ represent the current mainstream in broadband access. As a result of higher bandwidth and lower broadband access costs, a wider variety of value-added services ranging from broadband Internet access to bandwidth-consuming video applications will be offered. Telcos and ISPs will continue to offer value-added services including voice, data and new technologies like IP TV.

VDSL and ADSL are complementary technologies used in different network topologies. ADSL2 and 2+ are used for longer loop applications and dispersed subscribers, while VDSL2, the fastest offering of DSL, is used for applications requiring higher bandwidth within shorter loops. Due to the limitation in distance, VDSL2 is best used for tenants in densely populated locations. The symmetrical bandwidth of VDSL2 also makes it an optimal choice for a variety of applications such as video-conferencing and large file transfers.

Zyxel offers a range of ADSL 2+ solutions to suit different applications with both various sizes (number of ports) of the head end DSLAM concentrator and different types of the customer end ADSL2 + modems.

In the VDSL2 space both Motorola and Zyxel offer solutions for the “multi dwelling” environment including hotels, hospitals and dormitory style accommodation such as student accommodation and mining camps.
