Glossary Glossary ADSL Short for Asymmetric Digital Subscriber Line, a new technology that allows more data to be sent over existing copper telephone lines (POTS). ADSL supports data rates of from 1.5 to 9 Mbps when receiving data (known as the downstream rate) and from 16 to 640 Kbps when sending data (known as the upstream rate). ADSL requires a special ADSL modem. ATM Short for Asynchronous Transfer Mode, a network technology based on transferring data cells or packets of a fixed size.
Glossary Default A value or setting that a device or program automatically selects if you do not specify a substitute. Device Any machine or component that attaches to a computer. Examples of devices include disk drives, printers, mice and modems. DHCP Short for Dynamic Host Configuration Protocol, a protocol for assigning dynamic IP addresses to devices on a network. With dynamic addressing, a device can have a different IP address every time it connects to the network.
Glossary not between switching stations. xDSL is similar to ISDN in as much as both operate over existing copper telephone lines (POTS) and both require the short runs to a central telephone office. However, xDSL offers much higher speeds. DTAG One of two ADSL modes that the HM220di ADSL modem can operate in. DTAG is a proprietary ADSL mode used on ISDN lines mainly in Germany. Encapsulation A technology that enables one network to send its data via another network's connections.
Glossary IP Abbreviation of Internet Protocol, pronounced as two separate letters. IP specifies the format of packets, also called datagrams, and the addressing scheme. Most networks combine IP with a higher-level protocol called Transport Control Protocol (TCP), which establishes a virtual connection between a destination and a source. IP by itself is something like the postal system. It allows you to address a package and drop it in the system, but there is no direct link between you and the recipient.
Glossary Multimode One of four ADSL modes that the HM220dp ADSL modem can operate in. In multimode the modem will automatically detect the ADSL mode (T1.413, G.Dmt or G.Lite) using handshaking with the DSLAM equipment. NAT Short for Network Address Translation, an Internet standard that enables a local area network (LAN) to use one set of IP addresses for internal traffic and a second set of addresses for external traffic.
Glossary POTS Short for Plain Old Telephone Service, which refers to the standard telephone service that most homes use. In contrast, telephone services based on high-speed, digital communications lines, such as ISDN, are not POTS. The main differences between POTS and non-POTS services are speed and bandwidth. The POTS network is also called the Public Switched Telephone Network (PSTN). PPP Short for Point-to-Point Protocol, a method of connecting a computer to the Internet.
Glossary 10Base-T One of several adaptations of the Ethernet standard for Local Area Networks (LANs). The 10Base-T standard (also called Twisted Pair Ethernet) uses a twisted-pair cable with maximum lengths of 100 metres. Cables in the 10Base-T system connect with RJ-45 connectors. T1.413 One of four ADSL modes that the HM220dp ADSL modem can operate in. Asymmetric Digital Subscriber Line full rate according to ANSI T1.
