Glossary
Q
Encryption
public key used during encryption, and a corresponding private key used during
decryption.
QUIET
A state in the voice mode of ZyXEL modems. Quiet is detected after a long
pause in voice data.
RAM
Random Access Memory - working memory. The modem uses it among many
other uses to store information on sent, but not yet acknowledged data.
Redundancy
Extra data that does not generate additional information.
Remote
Location
The modem at the other end of the line (the one you are calling or that is
calling).

the receiving condition becomes bad.
RFC
An RFC (Request for Comments) is an Internet formal document or standard
that is the result of committee drafting and subsequent review by interested
parties. Some RFCs are informational in nature. Of those that are intended to
become Internet standards, the final version of the RFC becomes the standard
and no further comments or changes are permitted. Change can occur,
however, through subsequent RFCs.
ROM
Read Only Memory. The ROM holds the system software and the profiles and
settings of the modem (refer to EEPROM).
Router
A device that connects two networks together. Routers monitor, direct, and filter
information that passes between these networks. Because of their location,
routers are a good place to install traffic or mail filters. Routers are also prone to
attacks because they contain a great deal of information about a network.
RS
Abbreviation of recommended standard.
RTS/CTS
See CTS/RTS.
RXD
Line for the received data on a serial port following RS-232C.
Security
Function
Features of the ZyXEL modems that help deny illegitimate contacts to your
computer system through telephone lines.
