Capitolo 1: Introduzione
Nozioni sull’ ADSL
Asymmetric Digital Subscriber Line (ADSL) è una tecnologia in grado di trasferire dati ad alta
velocità tramite la comune linea telefonica voce su rame. ADLS è infatti in grado di far
coesistere la tradizionale voce su linea telefonica e il trasferimento dati. ADSl è la migliore
scelta per l’uso domestico e di piccolo uffici in quanto non necessità di costosi impianti
addizionali.
Esistono numerosi standard di modulazione ADSL. Il modem da lei acquistato è in grado di
supportare i seguenti standard: ANSI T1.413 Issue 2, ITU G.992.1 (G.DMT), ITU G.992.2
(G.lite), and CAP (T1 TR-59) and ITU G.992 Annexes A,B and C doce applicabile.
Protocolli e selezione driver.
Il modem ADSL Nortek Jet è facilmente installabile su qualsiasi PC tramite una tradizionale
porta USB (Universal Serial Bus) ed è in qualsiasi momento aggiornabile con nuovi firmware
rilasciati per standard futuri
Il modem Jet include la funzionalità ATM (Asynchronous Transfer Mode). ATM è un protocollo
in grado di suddividere I pacchetti internet in piccole dimensioni prefissate per una
trasmissione ancora più rapida sulla rete ad alta velocità. ATM è in grado di supportare
diverse tipologie di traffico (es: data, voce, video) in modo sicuro ed efficiente.
Sono disponibili differenti protocolli per l’suo di ATM. Questi protocolli sono normalmente
richiesti dal providers di servizi internet.
Le possibilità sono:
1. Point to Point Protocol (PPP) Over ATM (RFC 2364)
2. Bridged/Routed Ethernet/IP over ATM (RFC 1483)
3. RFC 1577.
4. Point to Point Protocol Over Ethernet (PPPoE) – RFC 2516
Il modem ADSL Nortek jet è in grado di funzionare in tre diverse modalità: WAN, LAN, e ATM.
Nota: tutte e tre le modalità sono in grado di lavorare con il protocollo ATM ma la modalità
ATM supporta anche il servizio ATM disponibile con i nuovi sistemi operativi. La scelta più
appropriata è dipendente dal sistema operativo e dal protocollo utilizzato dall’ISP (Internet
Service Providers)
1. LAN driver (RFC 1483 / RFC 1577) – questa modalità fa si che il modem appaia
come una periferica LAN o Ethernet. La connessione è stabilita automaticamente.
Questa modalità supporta: RFC 1483 and RFC 1577 con cnnessione PVC. La
connessione PPPoE è gestita solo tramite software di terze parti. E’ utilizzabile tramite
sistemi operativi Windows 98, Windows 98 SE, Windows Me, Windows 2000 e
Windows XP.
2. WAN driver (RFC2364 / RFC2516) – questa modalità gestisce il modem tramite una
2

connessione di tipo dial-up network. La modalità supporta: RFC 2364 and RFC 2516
con connessione PVC. E’ utilizzabile tramite sistemi operativi Windows 98, Windows
98 SE, Windows Me, Windows 2000 and Windows XP.
3. ATM driver (RFC2364) –questa modalità è utilizzabile unitamente ai servizi ATM di
Windows. La modalità ATM usa Dial-Up Networking per creare una connessione PVC
O SVC e stabilire una connessione PPP (RFC 2364). La modalità è utilizzabile tramite
sistemi operativi: Windows 98 SE, Windows Me, Windows 2000 and Windows XP.

informazioni sullo stato corrente del modem. Se
una luce verde è accesa in Link status indica che è
stata effettuata una connessione. Se la luce
lampeggia indica che si sta inizializzando una nuova
connessione. Data Activity fornisce invece
visivamente i trasferimenti dati della connessione
tramite il lampeggiamento degli indicatori gialli.

Chapter 1: Overview
About ADSL
Asymmetric Digital Subscriber Line (ADSL) technology provides high-speed data access across
regular phone lines (copper wires) by making use of previously unused frequency bandwidth
above the voice band. By placing the ADSL signal above the frequency of the voice signal,
ADSL service is able to coexist on the same line with your telephone service. ADSL is
asymmetric in the sense that it provides a higher data rate in the downstream (receive)
direction than in the upstream (transmit) direction. Asymmetric operation is ideal for typical
home and small office use where files and information are downloaded more frequently than
uploaded.
There are several standard types of ADSL modulation techniques including Discrete Multitone
(DMT) and Carrierless Amplitude and Phase (CAP). The ADSL Nortek jet Modemis capable of
supporting the following DSL standards: ANSI T1.413 Issue 2, ITU G.992.1 (G.DMT), ITU
G.992.2 (G.lite), and CAP (T1 TR-59) and ITU G.992 Annexes A,B and C as applicable.
Protocol and Device Driver Selection
The ADSL Nortek jet Modemcan be easily connected to a USB port on the PC via a standard
USB cable. The ADSL Nortek jet Modemis fully software upgradeable so that new features
and updates may be added by simply loading a new version of the device driver onto your
PC.
ADSL modems employ ATM (Asynchronous Transfer Mode) framing. ATM is a protocol that
divides packets into small fixed sized cells for rapid transmission over high-speed networks.
The ATM protocol allows various types of traffic (e.g. data, voice, and video) to be securely
and efficiently carried over the same network. ATM is being widely deployed by
telecommunications carriers in their backbone networks. Two type of ATM connections are
possible, PVC (Permanent Virtual Circuit) and SVC (Switched Virtual Circuit).
Several different protocols are used on top of ATM. The protocol required in your
configuration depends on the equipment deployed by your DSL service provider. There are
several possibilities:
1. Point to Point Protocol (PPP) Over ATM (RFC 2364) - PPP provides session setup,
user authentication (login), and encapsulation for upper layer protocols such as IP
(Internet Protocol). The use of PPP makes the modem appear as a dial modem to
the operating system. Dial-Up Networking is used to establish a connection. PPP is
supported by either the WAN (Wide Area Network) driver, or the ATM driver.
2. Bridged/Routed Ethernet/IP over ATM (RFC 1483) – This protocol makes the modem
appear as a local area network (LAN) device to the operating system.
3. RFC 1577 – this is another local area network like protocol for IP address and ATM
address mapping.
4. RFC 2516 - Point to Point Protocol Over Ethernet (PPPoE) - This protocol is a
specification for connecting multiple computer users on an Ethernet to a remote site
through common customer premises equipment. PPPoE can be used to have an office
or building-full of users share a common DSL (Digital Subscriber Line) connection to
16

the internet. PPPoE combines the Point-to-Point Protocol commonly used in dialup
connections, with the Ethernet protocol, which supports multiple users in a local area
network. The PPP Protocol information is encapsulated within an Ethernet frame.
Three types of device drivers are provided for the GlobespanVirata ADSL USB modem, WAN,
LAN, and ATM. Note that all three drivers support ATM protocol. In addition, the ATM driver
works with ATM services that are available in recent Windows operating systems. The proper
choice of driver depends on the combination of Windows operating system and protocol.
1. LAN driver (RFC 1483 / RFC 1577) – this driver makes the modem appear as a LAN
or Ethernet device. Connection establishment is automatic. This driver supports both
RFC 1483 and RFC 1577 with PVC connections. Additionally, PPPoE is supported by
third party software. It can be used with Windows 98, Windows 98 SE, Windows Me,
Windows 2000 and Windows XP.
2. WAN driver (RFC2364 / RFC2516) – this driver causes the modem to resemble a
dial-up modem. Call establishment is performed through Dial-Up Networking. This
driver supports both RFC 2364 and RFC 2516 with PVC connections. It can be used
with Windows 98, Windows 98 SE, Windows Me, Windows 2000 and Windows XP.
3. ATM driver (RFC2364) – this driver works in conjunction with ATM services provided
by Windows. The ATM driver uses Dial-Up Networking to create a PVC or SVC
connection to establish a PPP (RFC 2364) connection. This driver can be used with
Windows 98 SE, Windows Me, Windows 2000 and Windows XP.
