Glossary
1. Make sure that the connections to the ADSL modem are correct, that the port used
(Ethernet or USB) is working correctly and that the modem is on.
2. Check that the IP address in the browser address bar is 192.168.1.1
10/10 0Base-T
10/100Base-T uses an unshielded UTP cable (category 5) for Fast Ethernet connections. The
cable meets IEEE standard 802.3, has a maximum length of 100 meters and a transmission
speed of 100 Mbps.
ADSL
Abbreviation of Asymmetrical Digital Subscriber Line. Transmission technology using tele-
phone lines. The high frequencies used by ADSL co-exist with voice frequencies, allowing
basic telephone services and high-speed Internet connections to be used simultaneously.
Depending on the configuration chosen by the telephone carrier, ADSL can reach data speeds
of up to 8 Mbps downstream and 2 Mbps upstream.
ATM
Asynchronous Transfer Mode, which transfers multiple traffic (such as voice, video and data)
in cells with a fixed length of 53 bytes (instead of in "packets" of variable length as is the case
with Ethernet and FDDI technologies). ATM allows high speeds to be achieved and is particu-
larly common in high-traffic network backbones. Next-generation network devices also enable
ATM to be used for WAN transmissions, which will make it useful for large organizations that
are spread over a wide area.
Bridge
"Bridge" between two networks. When it receives a data packet, instead of propagating it
indiscriminately, the bridge recognizes the address and sends it to the relevant subnetwork,
avoiding the unnecessary propagation of traffic and consequently limiting collisions between
data packets.
CPE
Customer Premises Equipment. User equipment such as terminals, telephones and modems
supplied by the telephone company, installed at the user's premises and connected to the
telephone network. These devices may also belong to the user.
DHCP
Dynamic Host Configuration Protocol. This protocol allows network administrators to centrally
and automatically manage the allocation of IP addresses to all devices connected to a network
(which must be unique).
