Modem -
A combination of the words MOdulator and DEModulator.
Modems transform digital data into analog signals and back again.
Nonvolatile Memory -
An area of memory inside the modem where the
default configuration profile is stored. Values recorded in this memory will
not be lost when the power is turned off.
Off-Hook -
The condition when the modem has picked up the telephone
line.
Off-Line Command State -
A modem state in which the modem accepts,
interprets and executes commands from an asynchronous computer or
terminal.
On-Hook -
The condition when the modem has not picked up the telephone
line; the telephone is hung up.
On-Line -
A carrier signal link with a remote modem has been established;
communication is in progress.
On-Line State -
A modem state in which the modem is connected with a
remote modem. Data can be sent or received from the remote modem in this
state. No commands will be accepted from the modem except the escape
command which will bring the modem into the on-line command state.
On-Line Command State -
A modem state in which the modem can
accept or and execute commands from an asynchronous computer or terminal
while remaining connected with the remote modem. The user can return the
modem to the on-line state by issuing the
AT0n
command or put it into the
off-line command state by issuing commands such as
ATZ
or
ATH
.
Parity -
An error-checking method by which the modem verifies that the
data just sent is correct.
pps -
Pulse per second.
Profile -
A list of default settings.
Protocol -
A technical specification for serial communications; the
protocols supported by the modem are listed in Appendix B.
PSK -
Phase Shift Keying.
Pulse Dialing -
A dialing form in which each digit is represented by a
series of pulses. Rotary telephones all use pulse dialing.
QAM -
Quadrature Amplitude Modulation.
Result Codes -
The response the modem returns to the screen upon
executing a command.
