Malibu Networks AirMAX“ CPE/BTS
Router 
A network-layer device that connects networks using the same 
network-layer protocol, such as TCP/IP. 
Semipermanent 
Connection
A connection established via a telephone company service order. 
Server 
A powerful computer host providing shared files and resources to 
network users. 
Service Exchange 
Points (SEP)
These are points along a backbone where Network Providers allow 
traffic to cross between their network and another private network or 
the public Internet. Service Exchange Points are monitored so that 
only traffic destined for a paying customer is allowed to enter the 
private network.
Service Management 
System (SMS)
SMS is a Malibu Networks proprietary software option that manages 
all aspects of AirMAX systems. It provides a robust suite of functions, 
from top-level network management integration, to system element 
management, to customer provisioning and management. 
Session 
An online communications connection between two nodes. 
Simple Network 
Management Protocol 
(SNMP) 
A protocol used for gathering management information from network 
devices. SNMP is the standard protocol for network management.
Subnet Mask 
See address mask. 
Subnetting
Configuring servers using alternate data paths. Subnetting reduces 
network traffic and still allows connection when single paths fail. 
T-1
North American standard for point-to-point digital circuits over two 
twisted pairs. Such a line can carry 24 64,000bps channels, allowing a 
usable bit rate of 1,536,000bps. Customers may lease all of a T-1 line 
or a fractional T-1 with only some of the 24 channels. A T-1C contains 
two T-1 lines. In Europe and Japan E-1 through E-5 offer similar 
features with differing numbers of channels and different data rates.
T-2
T-2 is the equivalent of four T-1s, offering 4 T-1 circuits with a 6.3Mbits/
sec of bandwidth. T-2 is not commercially available, but rather is used 
within the telephone company service system. 
T-3
T-3 supports 28 multiplexed T-1 circuits and provides 44.736Mbits/sec 
of bandwidth. 
T-4
T-4 consists of 168 T-1 circuits.
