GLOSSARY 159
Modem’s two 56K lines, Multilink PPP is used to combine these two 56K
connections into a virtual, single 112K connection.
NetBIOS filtering NetBIOS filtering is a LAN Modem feature that helps prevent the LAN Modem
from establishing unwanted calls. This feature filters the DNS requests made by
NetBIOS that inadvertently cause the LAN Modem to place a call. NetBIOS is a
protocol primarily used by Windows 98, 95 and NT for local file and printer
sharing.
off hook/on hook Modem operations that are the equivalent of manually lifting a phone receiver
(taking it off-hook) and replacing it (going on-hook).
PAP Password Authentication Protocol. PAP is one of two PPP authentication protocols;
CHAP is the other. An authentication protocol requests information to verify a
valid user. PAP requests the user’s name and password for verification.
PC/TCP PC/TCP is a PC version of TCP/IP created by FTP software.
POTS Plain old telephone service.
PPP Point-to-Point Protocol. PPP provides a standard method of transmitting data
through the Internet. PPP is used for communication between a computer and an
Internet Service Provider.
PPTP Point-to-Point Tunneling Protocol. PPTP is a protocol that allows for Windows 95
and Windows NT systems to establish a secure connection to a remote, private
network via a locally-dialed ISP account.
router A router is a device that links two or more networks together by forwarding data
packets to their proper destinations according to network addresses contained
within the packet headers. Routers use address tables to perform this function and
are considered “intelligent” in their ability to make decisions about the most
efficient route through which to send each packet. A router often serves as the
link between a LAN and WAN.
Service Provider As used by the Dual 56K LAN Modem, the term Service Provider applies to any
remote dial-out destination. The LAN Modem recognizes two categories of Service
Providers: Internet Service Providers (see also ISP), which provide a direct
connection to the Internet, and Private Network Service Providers, which provide a
direct connection to a remote Private Network, such as a corporate office LAN.
server-side Within a client/server network environment, server refers to the device which
supplies, maintains, and/or processes information or services which are requested
and by other, receiving client devices. In the context of the LAN Modem’s dial-in
scenarios, server-side refers to the LAN Modem that receives the dial-in call from
the calling party. (See also client-server.)
TCP/IP Transmission Control Protocol/Internet Protocol. TCP/IP is a standardized
communications protocol which allows different types of devices to communicate
with each other over LANs and WANs.
UDP User Datagram Protocol. UDP converts application data messages into packets to
be sent via the Internet Protocol (IP), but does not verify a successful transmission.
In this way, UDP is more efficient that TCP, leaving the reliability on the application
that generates the message.
