TERM DEFINED
Element
Management
System
The Element Management System (EMS), located on a
workstation at an appropriate point in the network, allows you to
configure, control, and monitor all components of the AB-Access
System.
MIB
Management information base allows external management
system access.
Multiplexer
A multiplexer is device or system capable of combining
elementary streams into one aggregate transport stream.
Network
A network is an interconnection of computer systems, terminals,
or data communications facilities.
OC3
A data transmission rate of 155 Mbps
Packet
A packet is a sequence of data, with associated control
information, that is switched and transmitted as a whole.
Packet Switching
Packet switching is the data transmission method that divides
messages into standard-sized packets for greater efficiency of
routing and transport through a network.
Parsing
Parsing is the process of analyzing a data stream and breaking it
down into more easily processed components.
Permanent Virtual
Circuit
Provides end-to-end connectivity for transmission in a network.
Point-to-Point
A single communication circuit connecting two locations.
Point-to-Multipoint
A communications circuit connecting one location to many
locations.
Radio Frequency
Radio frequency (RF) is a portion of the electromagnetic spectrum
in the frequency range of 100 kHz to 20 GHz.
Subscriber Unit
The Subscriber Unit (SU) is the part of the AB-
A
ccess System that
is installed at the customer premises and provides communication
with the Base Station (BS).
Synchronous
A data transmission method in which data transfer is at a fixed
rate. The transmitter and receiver are both controlled by clock
pulses.
TCP/IP
Transmission Control Protocol/Internet Protocol, a layered set of
protocols that allows sharing of applications among PCs, hosts, or
workstations in a high-speed communications environment. The
suite of protocols is designed to allow communication between
networks regardless of the technologies implemented in each
network.
TDD
Time Division Duplex, the transmission method where a single
channel is used to alternately carry data in each direction of a link.
Time-Division
Multiplexing
A form of multiplexing used with digital signals. A device scans
individual channels in rotation, takes bits from each channel,
transmits the bits in a string (according to a predetermined
sequence), and repeats the process.
