RIP
Routing Information Protocol is an interior or intra-domain routing protocol that uses
distance-vector routing algorithms. RIP is used on the Internet and is common in the
NetWare environment as a method for exchanging routing information between
routers.
Rom-0
This is the name of the configuration file on your ZyXEL device. Renaming may be
necessary when uploading a new configuration file to your ZyXEL device.
Router A device that connects two networks together. Routers monitor, direct and filter
information that passes between these networks. Because of their location, routers are
a good place to install traffic or mail filters. Routers are also prone to attacks because
they contain a great deal of information about a network.
SAP
In NetWare, the SAP (Service Advertising Protocol) broadcasts information about
available services on the network that other network devices can listen to. A server
sends out SAP messages every 60 seconds. A server also sends out SAP messages to
inform other devices that it is closing down. Workstations use SAP to find services
they need on the network.
SDSL
A Symmetrical Digital Subscriber Line is a symmetrical, bi-directional DSL service
that operates on one twisted-pair wire. It can provide data rates up to the T1 rate of
1.544 Mbits/sec, and it operates above the voice frequency, so voice and data can be
carried on the same wire.
Server A computer, or a software package, that provides a specific kind of service to client
software running on other computers.
SMT
System Management Terminal. The SMT is a menu-based interface that you use to
configure your device.
Splitter In telephony, a splitter, sometimes called a “plain old telephone service splitter" is a
device that divides a telephone signal into two or more signals, each carrying a
selected frequency range, and can also reassemble signals from multiple signal
sources into a single signal
STP Shielded Twisted-Pair cable consists of copper-core wires surrounded by an insulator.
Two wires are twisted together to form a pair; the pair form a balanced circuit. The
twisting prevents interference problems, STP provides protection against external
crosstalk.
Straight-through
Ethernet cable
A cable that wires a pin to its equivalent pin. This cable connects two dissimilar
devices, for example, a data terminal equipment (DTE) device and a data
communications equipment (DCE) device. A straight through Ethernet cable is the
most commonly used Ethernet cable.
