VDSL, the fastest offering of DSL, provides a much higher bandwidth than other DSL technologies. Ethernet over VDSL extends Ethernet over single-pair copper wiring at distances of up to 1.5km. This technology provides a cost-effective, readily available, and rapidly deployable solution that offers needed bandwidth to multi-tenant units (MTUs).
VDSL has changed the fundamental economics of broadband services for the MTU marketplace. Tenants don't have to suffer the limited bandwidth. Even small to medium-sized corporations can receive the same services as large companies. With VDSL, MTUs gain a cost-effective broadband solution that preserves their existing infrastructure, and in the process, building owners or service providers receive a compelling new source for revenue generation.
ZyXEL's VDSL solution is comprised of a VDSL Ethernet switch , VES-1012 and a CPE modem, Prestige 841. The VES-1012 multiplexes traffic from 12 VDSL subscribers into one or two 100M Ethernet ports that connect to any Ethernet switch or broadband router. With the VES-1012, Ethernet over VDSL can run up to 1.5km at the speed of 5Mbps, which proves to be a promising technology and revenue generation tool for building owners and service providers.
Bandwidth of 5 to 15 Mbps Per Port in Full Duplex
Allows building owners and service providers to offer a variety of value-added services ranging from broadband Internet access to bandwidth-consuming video applications.
Broadband over Existing Telephone Wires
With VDSL, broadband service could be offered using the existing copper wires. New revenue could be generated with minimum installation time and expense.
Co-existence with Plain Old Telephone Service (POTS), Digital Phones and ISDN
VDSL can be implemented quickly, even if building owners have just one phone line per tenant. The existing POTS or ISDN services could be kept while adding new broadband services.
New Advances for Broadband Service Offering
The VLAN feature in the VES-1012 offers the benefits of both security and performance. Multicasting design improves network bandwidth utilization for bandwidth-consuming application, such as video on demand. New mechanisms, such as 802.1p, have also emerged to ensure quality of service. The new advances in the VES-1012 enable service providers to turn on broadband service to more customers quickly and at a lower cost than previously possible.
MTU-oriented Services
When service providers bring fiber closer to the end users, VDSL becomes the best solution for delivering broadband service to people working or living insides the buildings, such as business parks, apartments, dormitories, campus and hospitality.
Scalable Platform for Future Expansion
The flexible design of the VES-1012 allows service providers to start VDSL service at a minimum cost. As the number of subscribers and applications grow, the additional VES-1012 can be added to increase the available customer base.
