Perle 833IS User Guide 303
RISC (Reduced Instruction Set Computer)
A microprocessor architecture that simplifies the operating
commands of a device to enable it to operate at high
speeds.
RJ11
The most common telephone jack in the world. Used for
voice transmissions.
RJ-45
A jack used for data transmissions over a standard
telephone wire.
RJ-48C
An 8 position keyed plug used for connecting T-1 circuits.
Roaming Callback
A method where the client supplies the number for callback
when they dial in.
Router
A device that connects Lans’ at the network level and
directs calls to applications. Like a bridge except that it can
examine network addresses and determine the most
efficient path for a frame to reach its destination. See Bridge
SAP (Service Advertising Protocol)
A protocol used by Novell NetWare devices to broadcast
their names, addresses, and current state on the network.
Security Dynamics SecurID
A third party Token system security device.
SNAP (Subnetwork Access Protocol)
This is an Internet protocol that lets you use non-standard
protocols. It is a mechanism that will distinguish one
protocol from another.
SNMP (Simple Network Management Protocol)
A protocol for managing network devices.
Sockets
An interface for communicating between a user application
program and TCP/IP.
SPID (Service Profile Identifiers)
The Service Profile Identifier is a numeric string assigned to
an interface or channel by the service provider. The SPID
configured on the 833IS is sent to the service provider at
start-up. This is used by the service provider to assign
class of service to a channel.
Standard Profile
Used to define the user and their access to the network.
Static Routing
A route that you have manually entered in your routing
table. This route then takes precedence over any dynamic
routing protocol.
STP (Shielded Twisted Pair)
Twisted pair wiring that is enclosed in a metal foil sheath to
limit interference.
Subnet Mask
The IP network mask. Identifies the device’s IP address,
which portion constitutes the network address and which
portion constitutes the host address.
Support
A term that indicates that a particular piece of hardware or
software is either included with your computer or will work
with it.
TCP (Transmission Control Protocol)
A protocol that organizes packets, manages their
transmission and ensures their accurate delivery to the
receiving station. Usually combined with IP to produce
TCP/IP.
TCP/IP
A protocol suite developed by the U.S. Department of
Defense. Used to connect different types of computers
while providing data correction, security, and reliability.
Thinnet
A term used to describe thin Ethernet coaxial cable.
Time Division Multiplexing
A method of transmitting a number of different data types
(voice, video or data) together over one communications
medium. The various data types are reconstructed at the
destination end of transmission as separate and distinct
signals. This method saves money by using fewer phone
lines.
Token Ring
A LAN that conforms to the IEEE 802.5 Token Ring Access
Method standard.
