Chapter 1: About the VDSL Switch-VS2512A

Overview

Accton’s Ethernet-over-VDSL system consists of end-user CPEs (Customer

Premise Equipment) connected to a VDSL switch and splitter by standard telephone

cable. The VDSL connection delivers an Ethernet data link rated up to

15 Mbps symmetric (full duplex), while simultaneously supporting standard

telephone services. The system can be deployed in any multi-dwelling/multi-tenant

environment (apartment blocks, hotels, or office complex) to provide both high-

speed Internet access and telephone services without any need for re-wiring.

Accton’s VDSL Switch-VS2512A and VDSL-Splitter-VM2524/VM2548 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. A CPE is then used to separate these signals and pass

them on to a customer’s computer and telephone equipment. In-building

connections can operate up to 15 Mbps for runs up to 1070 m (3500 ft), 10 Mbps for

runs up to 1220 m (4000 ft), 5 Mbps for runs up to 1525 m (5000 ft).

Note: Category 3 cable must be installed to achieve the maximum distance, but the

distance may be limited by factors such as how the cable is bundled, and the

interference and noise on the link.

The VDSL switch and splitter are 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 100 Mbps or 1 Gbps connection. This kind of WAN

connection is referred to as Fiber To The Building (FTTB). Phone signals are routed

from PBX/MDF distribution equipment into the splitter. The data and phone signals

for each user are combined in the splitter, and passed over VDSL lines to individual

customers.

The CPE at the other end of the VDSL line connects to any PC or Macintosh

equipped with a 10/100BASE-TX network interface card. Your existing telephone,

modem, or fax machine simply plugs into the CPE’s phone port. There is no need for

special splitters, terminators or filters. In fact, there is no need to modify the home

wiring at all. And, because the VDSL connection is based on Ethernet, no further

complex software configuration is required.
