Glossary-4
Class
Understanding this methodology is difficult, even for customers. Therefore, let’s explain this in easier terms. The first octet
(or octets) defines the “class” (indicated by the word “net” in this example) of the address, which is the only method to tell
the size of the network (how big) and where the internet address belongs. The remaining octets indicate availability for net-
work equipment (i.e., computer or other network equipment). The three main classes are: Class A, Class B, and
Class C.
 Class A: Net, Node, Node, Node 255. 0.0.0
(last three octets are available for equipment)
 Class B: Net, Net, Node, Node 255.255 .0.0
(last two octets are available for equipment)
 Class C: Net, Net, Net, Node 255.255.255 .0
(last octet is available for equipment)
Coaxial Cable
A type of transmission line consisting of a center conductor wire surrounded by insulation that is in turn surrounded by a
conductive shield made of metal foil or wire braid. Often used to connect the RF unit and modem unit of a wireless
system.
Code Division Multiple Access (CDMA)
A system in which all users occupy the same bandwidth. Uncorrelated codes are used to allow for higher bandwidth occu-
pancy. This is also known as the spread spectrum system.
Common Management Information Protocol (CMIP)
A network management protocol that is consistent with an Open Systems Interconnection (OSI) network communication
model.
Company name
This is the name of the company that owns or maintains the radio given to the terminal.
