CHAPTER 1
Getting to Know Your Switch
This chapter introduces the main features and applications of the Switch.
1.1 Introduction
The Switch is a stand-alone layer-2 VDSL over Ethernet switch with two Telco-50 connectors for
VDSL and POTS connections. The switch also comes with one 10/100Base-TX Ethernet
management port, two Gigabit/mini-GBIC uplink ports and a console management port.
With its built-in Web Configurator, managing and configuring the Switch is easy. In addition, the
Switch can also be managed via Telnet, any terminal emulator program on the console port, or
third-party SNMP management.
See Chapter 48 on page 367 for a full list of software features available on the Switch.
This section shows a few examples of using the Switch in various network environments.
1.2 Applications
These are the main applications for the switch:
• Internet access and multimedia services for Multiple Tenant Units (MTU).
• Other applications include telemedicine, surveillance systems, remote servers systems, cellular
base stations and high-quality teleconferencing.
1.2.1 MTU Application
The following diagram depicts a typical application of the switch with the VDSL modems, in a large
residential building, or multiple tenant unit (MTU), that leverages existing phone line wiring to

provide Internet access to all tenants. Note that VDSL service can coexist with voice service on the
same line.

1.2.2 Curbside Application
The switch can also be used by an Internet Service Provider (ISP) in a street cabinet to form a “mini
POP (Point-of-Presence)” to provide broadband services to residential areas that are too far away
