GLOSSARY

modem

A device that transmits/receives computer data

through a communications channel such as

radio or telephone lines. It also changes signals

received from the phone line back to digital

signals before passing them to the receiving

computer.

nonvolatile memory (NVRAM)

User-programmable random access memory

whose data is retained when power is turned

off. On the U.S. Robotics modem, it includes

four stored phone numbers and the modem

settings.

off/on hook

Modem operations that are the equivalent of

manually lifting a phone receiver (taking it off-

hook) and replacing it (going on-hook).

online fall back/fall forward

A feature that allows high-speed, error-control

modems to monitor line quality and fall back to

the next lower speed in a defined range if line

quality diminishes. As line conditions improve,

the modems switch up to the next higher

speed.

originate mode

The mode used by your modem when initiating

an outgoing call to a destination modem. The

transmit/receive frequencies are the reverse of

the called modem, which is in answer mode.
