Stands for Asymmetric Digital Subscriber Line. If you use ADSL, the central office will be
connected to each home directly in a 1:1 method. In a down-link where data is transferred
downward from the central office to the users, high-speed data communications of at least
1.5 Mb can be made. On the contrary, in an up-link from the users to the central office,
communications are made very slowly. Thus, this service is called an asymmetrical service
not a symmetrical service.
Stands for VoIP Plug & Play Management Software. This integrated management software
developed by AddPac Technology enables VoIP products to be installed in a GUI
environment, be monitored in real-time, or to be upgraded. This software also enables
network administration.
Stands for Application Programming Interface. API is a function call legend standard that
defines service interfaces.
Stands for AddPac Internetworking Operation System. This is an operating system that
supports the network products developed by AddPac Technology.
Stands for Asynchronous Transfer Mode. This is an international cell relay standard for
providing a variety of services such as voice, video, and data in the form of a cell of a fixed
length (53 bytes). If you use a fixed-length cell, cell processing will be performed in the
hardware; thus, transmission delay can be reduced. ATM is designed to make use of high-
speed transmission media such as E3, SONET, and T3.
This network has been commercialized by the Korean government since 1993. The high-
speed national network designed for governmental offices provides data services (transport
network services) and Internet services. Data services are categorized into ATM, dedicated
lines, packet exchange, and frame relay services. Internet services are categorized into
Internet multi-services provided through ATM connection circuits and simple Internet
services.
This is an international organization founded by Cisco Systems, NET/ADAPTIVE,
Northern Telecom, and Sprint in 1991 to reach the agreement of a standard for ATM
technologies. ATM Forum expands the formal standards developed by ANSI and ITU-T
and the agreements on the implementation of technologies.
