Glossary
Active Network Session
An active network session allows you to send and receive data across the
Internet using point-to-point protocol through your network connection.
AT Commands
AT commands are a language type that enables PC communications software
to give the modem directions. The term “AT” comes from the command
terminology which always begins with “attention”, or AT.
Baud
The unit in which the information carrying capacity or "signalling rate" of a
communication channel is measured.
Baud Rate
The speed at which a signal is transmitted over a communication channel.
CDPD
Cellular Digital Packet Data (CDPD) is a wireless data transmission
technology that uses unused cellular channels to transmit packets of data. To
send and receive data across the Internet, a CDPD or “wireless IP” modem
must first register to the CDPD network.
Channel
The range of CDPD frequencies used to transmit and receive data is broken
up into channels, which act as individual paths for communication. Each of
these channels is assigned a number. Each channel number represents a range
of frequencies.
De-registration
De-registration involves disconnecting and closing the communication path
being used on the CDPD network. When the modem is de-registered, it can
no longer send data across the network.
Domain Name System (DNS)
This is a network server used on IP networks, such as the Internet, for
translating network hostnames and Universal Resource Locators (HURL’s)
into IP addresses.
Domain Name System (DNS) Address
The IP (internet protocol) address of the Domain Name System (DNS).
