ADSL
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.
AP-VPMS
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.

ATM
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.
