A.1 Terms and Definitions
Term Definition
Access Point An Access Point (AP) is a component of a Base Station (BS) that
contains the antenna used to communicate with a Customer Premise
Equipment (CPE).
Antenna A device for transmitting and/or receiving radio waves.
Asynchronous A data transmission method in which data may be sent at irregular
intervals (without reference to clock signals).
Available Bit Rate
(ABR) Service that provides rate-based flow control and is aimed at data
traffic such as file transfer and e-mail.
Azimuth The angle along the horizon usually referenced to north.
Bandwidth The data carrying capacity of a communications channel, measured
in Hertz as the difference between the highest and lowest frequencies
of the channel.
Base Station The Base Station is the part of the AB-MAX System that sends
signals to and receives signals from the Customer Premise
Equipment (CPEs) to enable communication with the WAN.
Baud A measure of data transmission speed. The baud rate denotes the
number of symbols per second.
Bit Error Rate The Bit Error Rate (BER) is the fraction of transmitted bits that are
received in error.
Constant Bit Rate
(CBR) Service that operates on a connection basis and offers consistent
delay predictability; used for applications such as circuit emulation,
voice, and video.
DS1 A data transmission rate of 1.544 Mbps, also referred to as a T-1.
DS3 A data transmission rate of 45 Mbps
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-MAX 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.
