L Glossary
PSTN
Public Switched Telephone Network was put into place many years ago as a voice
telephone call-switching system. The system transmits voice calls as analog signals
across copper twisted cables from homes and businesses to neighborhood COs (central
offices); this is often called the local loop. The PSTN is a circuit-switched system,
meaning that an end-to-end private circuit is established between caller and the person
called.
Q
R
ras
This is the name of the firmware on the ZyXEL device. Renaming may be necessary
when uploading new firmware to the device.
RFC
An RFC (Request for Comments) is an Internet formal document or standard that is the
result of committee drafting and subsequent review by interested parties. Some RFCs
are informational in nature. Of those that are intended to become Internet standards, the
final version of the RFC becomes the standard and no further comments or changes are
permitted. Change can occur, however, through subsequent RFCs.
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.
S
SNMP
Simple Network Management Protocol is a popular management protocol defined by
the Internet community for TCP/IP networks. It is a communication protocol for
collecting information from devices on the network.
Static Routing
Static routes tell routing information that a networking device cannot learn
automatically through other means. The need for static routing can arise in cases where
RIP is disabled on the LAN or a remote network is beyond the one that is directly
connected to a remote node.
STP
Shielded Twisted-Pair cable consists of copper-core wires surrounded by an insulator.
