Chapter 1: Introduction
Overview
This device can serve as a key component in any Ethernet-over-VDSL2 data transport
system that consists of an end-user Gateway and a VDSL2 switch connected by
standard telephone cable. The VDSL connection delivers an Ethernet data link rated
up to both 100 Mbps downstream and 100 Mbps upstream (VDSL2 profile 30A), while
simultaneously supporting standard telephone services. The system can be deployed
in any multi-dwelling/multi-tenant environment (apartment blocks, hotels, or office
complexes) to provide both high-speed Internet access and telephone services without
any need for re-wiring. It also provides a built-in 802.11b/g access point for wireless
connectivity.
VDSL switches combine both the data and phone signals coming from your Internet
and telephone service providers, and pass these signals directly over standard
telephone wiring to multiple users in the same building. The Gateway is used to
separate these signals and pass them on to a customer’s computer and telephone
equipment.
The VDSL2 switch is typically located in a wiring closet or other central location of a
multi-dwelling/multi-tenant unit, campus, or enterprise. An Internet connection is
provided from the ISP to the customer’s building over fiber optic cable, running
Ethernet directly over a 1 to 10 Gbps connection. This kind of WAN connection is
referred to as Fiber To The Building (FTTB). Data signals entering a site are first
passed through an Ethernet switch that segregates the signals for individual user
connections, and are then fed into the switch. Phone signals are also routed from PBX/
MDF distribution equipment into the switch. The data and phone signals for each user
are combined in the switch, and passed over VDSL lines to individual customers.
The Gateway at the customer end of the VDSL line connects to any PC equipped with
a 10BASE-T or 100BASE-TX network interface card. Your existing telephone, modem,
or fax machine simply plugs into the Gateway’s phone port. There is no need for
splitters, terminators, or filters. In fact, there is no need to modify your home wiring at
all. And because the VDSL connection is based on Ethernet, no complex software
configuration is required.
The Gateway provides access to a wide range of advanced transport features,
including support for real-time video, and other multimedia services requiring
guaranteed Quality of Service (QoS). It also provides multiprotocol encapsulation for
bridging Windows NetBEUI and Novell’s IPX protocols directly to a remote site for
complete access to corporate resources, or for routing TCP/IP traffic for Internet
connections.
