Paradyne manual Default A pre-defined original value, 6212-A2-GB20-20, July

data rate: The speed measured in bits per second that data is transferred over the carrier line.

Default: A pre-defined original value.

demodulation: The recovery, from a modulated carrier, of a signal.

DHCP server: A server that dynamically allocates network addresses and delivers configuration parameters to hosts.

DHCP: Dynamic Host Configuration Protocol. A TCP/IP protocol that enables a network connected to the Internet to automatically assign a temporary IP address to a host when the host connects to the network.

digital signal: A discrete or discontinuous signal where the states are discrete intervals apart, such as +10 volts and –10 volts. These states are then represented by the binary digits 0 and 1.

digital: loopback test: A test that connects the device’s receiver output back to the transmitter input. This test will disrupt the transmission of primary data.

DLL: Dynamic Link Library. DLLs are files that are automatically loaded into memory when required.

DMT: Discrete MultiTone. The T1.413 standard modulation scheme for Digital Subscriber Line technology.

DNS: Domain Name Server. A server that retains the addresses and routing information for TCP/IP PAT users.

download: To receive a file over a network (compare with upload).

driver: A software module that provides an interface between a network interface card and the upper-layer protocol software running on a computer.

DSL: Digital Subscriber Line. A family of broadband services provided over a traditional phone line, such as ADSL, SHDSL, and VDSL.

DSP: Digital Signal Processor. The microprocessor that handles line signaling in a modem.

DTE: Data Terminal Equipment. Equipment that transmits or receives data in the form of digital signals.

dynamic detection: A process of a automatic detection of a new device added or removed from the PC.

EOC: Embedded Operations Channel. An in-band channel between DSL devices that operates at the physical layer for administration and maintenance data.
