Summit WM20 User Guide, Software Release 4.2

NTP

Network Time Protocol, an Internet standard protocol (built on top of 
TCP/IP) that assures accurate synchronization to the millisecond of 
computer clock times in a network of computers. Based on UTC, NTP 
synchronizes client workstation clocks to the U.S. Naval Observatory 
Master Clocks in Washington, DC and Colorado Springs CO. Running 
as a continuous background client program on a computer, NTP sends 
periodic time requests to servers, obtaining server time stamps and 
using them to adjust the client's clock. (RFC1305)

O

OFDM

Orthogonal frequency division multiplexing, a method of digital 
modulation in which a signal is split into several narrowband 
channels at different frequencies. OFDM is similar to conventional 
frequency division multiplexing (FDM). The difference lies in the way 
in which the signals are modulated and demodulated. Priority is given 
to minimizing the interference, or crosstalk, among the channels and 
symbols comprising the data stream. Less importance is placed on 
perfecting individual channels. 
OFDM is used in European digital audio broadcast services. It is also 
used in wireless local area networks. 

OID

Object Identifier. 

OPSEC

OPSEC (Open Platform for Security) is a security alliance program 
created by Check Point to enable an open industry-wide framework 
for interoperability of security products and applications. Products 
carrying the "Secured by Check Point" seal have been tested to 
guarantee integration and interoperability. 

OS

Operating system.

OSI

Open System Interconnection. An ISO standard for worldwide 
communications that defines a networking framework for 
implementing protocols in seven layers. Control is passed from one 
layer to the next, starting at the application layer in one station, down 
through the presentation, session, transport, network, data link layer 
to the physical layer at the bottom, over the channel to the next station 
and back up the hierarchy.

OSI Layer 2

At the Data Link layer (OSI Layer 2), data packets are encoded and 
decoded into bits. The data link layer has two sublayers: 
> The Logical Link Control (LLC) layer controls frame 
synchronization, flow control and error checking
> The Media Access Control (MAC) layer controls how a computer on 
the network gains access to the data and permission to transmit it. 

OSI Layer 3

The Network layer (OSI Layer 3) provides switching and routing 
technologies, creating logical paths, known as virtual circuits, for 
transmitting data from node to node. Routing and forwarding are 
functions of this layer, as well as addressing, internetworking, error 
handling, congestion control and packet sequencing.
