router:
A device that suppor ts network communications. A router can connect identical network types, such as
LocalTalk-to-LocalTalk, or dissimilar network types, such as LocalTalk-to-Ethernet. However—unless a gateway is
available—a common protocol, such as TCP/IP, must be used over both networks. Routers may be equipped to
provide WAN line suppor t to the LAN devices they ser ve. They may also provide various management and
monitoring functions as well as a variety of configuration capabilities.
router port:
A physical or logical connection between a router and a network. Where a network only allows the
use of one protocol, each physical connection corresponds to one logical router por t. An example is the Netopia
ISDN Router’s LocalTalk por t. Where a network allows the use of several protocols, each physical connection
may correspond to several logical router por ts—one for each protocol used. Each router por t has its own
network address.
routing table:
A list of networks maintained by each router on an internet. Information in the routing table
helps the router determine the next router to for ward packets to.
SDLC (Synchronous Data Link Control):
A link-level communications protocol used in an International
Business Machines (IBM) Systems Network Architecture (SNA) network that manages synchronous,
code-transparent, serial information transfer over a link connection. SDLC is a subset of the more generic HDLC
(High-Level Data Link Control) protocol developed by the International Organization for Standardization (ISO).
seeding:
A method for ensuring that two or more routers agree about which physical networks correspond to
which network numbers and zone names. There are three options: non-seeding, soft seeding, and hard seeding.
Seeding can often be set separately for each router por t. See

non-seeding, seed router,
and
soft seeding
.
seed router:
A router that provides network number and zone information to any router that star ts up on the
same network. See also
hard seeding
,
non-seeding, seeding,
and
soft seeding
.
serial port:
A connector on the back of the workstation through which data flows to and from a serial device.
server:
A device or system that has been specifically configured to provide a ser vice, usually to a group of
clients.
SNMP (Simple Network Management Protocol):
A protocol used for communication between management
consoles and network devices. The Netopia ISDN Router can be managed through SNMP.
soft seeding:
A router setting. In soft seeding, if a router that has just been reset detects a network number or
zone name conflict between its configured information for a par ticular por t and the information provided by
another router connected to that por t, it updates its configuration using the information provided by the other
router. See

subnet:
A network address created by using a subnet mask to specify that a number of bits in an internet
address will be used as a subnet number rather than a host address.
subnet mask:
A 32-bit number to specify which par t of an internet address is the network number, and which
par t is the host address. When written in binar y notation, each bit written as 1 corresponds to 1 bit of network
address information. One subnet mask applies to all IP devices on an individual IP network.
TCP/IP (Transmission Control Protocol/Internet Protocol):
An open network standard that defines how
devices from different manufacturers communicate with each other over one or more interconnected networks.
TCP/IP protocols are the foundation of the Internet, a worldwide network of networks connecting businesses,
governments, researchers, and educators.
telephone wall cable:
2-pair, 4-pair, or 8-pair, 22- or 24-gauge solid copper wire cable. Telephone wall cable is
sometimes called telephone station cable or twisted-pair cable.
