User's Guide for ZyXEL Omni 56K USB Modem

 

lines with some combination of asynchronous transfer mode (ATM), frame relay, or IP

 

networks.

DSR

Data Set Ready – a control signal line of the RS-232C standard.

DTE

Originally, the DTE (data terminal equipment) meant a dumb terminal or printer, but today

 

it is a computer, or a bridge or router that interconnects local area networks.

DTMF

Dual Tone Multi-Frequency. The technology used in pushbutton telephones, commonly

 

known as touchtone, of generating audible notes to represent numbers.

DTR

Data Terminal Ready – a control signal line of the RS-232C standard interface. Some

 

computers set this signal when they are turned on, even if they are not able to receive data.

Echo

For a modem user, echo has two meanings: A modem can return all received characters to

 

its local terminal/computer so they can be seen on-screen. The other meaning of the term

 

“echo” is that part of the analog signal the modem sent out is bounced back by the

 

telephone network to the modem's receiver, mixing there with the remote modem's signal.

EDR

Extended Distinctive Ring – A feature of ZyXEL modems that helps to distinguish between

 

data, fax and voice calls.

EEPROM

An Electronically Erasable and Programmable Read Only Memory. Such a device is used

 

in ZyXEL modems to store settings and profiles. An EEPROM does not lose data when the

 

modem is turned off.

EIA

Electronic Industry Association (of North America); this organization was the first to draft

 

a standard serial port (RS-232C).

EMI

ElectroMagnetic Interference. The interference by electromagnetic signals that can cause

 

reduced data integrity and increased error rates on transmission channels.

Encryption

The act of substituting numbers and characters in a file so that the file is unreadable until it

 

is decrypted. Encryption is usually done using a mathematical formula that determines how

 

the file is decrypted.

EPROM

Electrically Programmable Read Only Memory. A memory chip that may be programmed

 

electronically, but must be exposed to ultraviolet radiation to be erased.

Error Correction

A method to compensate for errors which occurred in the transmission path. Error

 

correction is done by the modems and is transparent to the DTEs. The most familiar

 

correction methods are MNP5 and V.42bis.

Ethernet

A very common method of networking computers in a LAN. There are a number of

 

adaptations to the IEEE 802.3 Ethernet standard, including adaptations with data rates of 10

 

Mbits/sec and 100 Mbits/sec over coaxial cable, twisted-pair cable, and fiber-optic cable.

 

The latest version of Ethernet, Gigabit Ethernet, has a data rate of 1 Gbit/sec.

Events

These are network activities. Some activities are direct attacks on your system, while others

 

might be depending on the circumstances. Therefore, any activity, regardless of severity is

 

called an event. An event may or may not be a direct attack on your system.

FAQ

(Frequently Asked Questions) – FAQs are documents that list and answer the most

 

common questions on a particular subject.

Fax

Long distance copy; facsimile – transfer of graphical data between two fax units. The

 

graphical data is compressed during transfer (G3).
