10Base-T
The most widely installed Ethernet local area networks (LANs) use
ordinary telephone twisted-pair wire. When used on Ethernet, this carrier
medium is known at 10BASE-T. 10BASE-T supports Ethernet’s 10
Mbps transmission speed.
100Base-TX
100Base-TX is a 100 Mbps local area network, know as Fast Ethernet.
ADPCM
Adaptive Differential Pulse Code Modulation. A speech coding method
which uses fewer bits than the traditional PCM (Pulse Code Modulation).
ADPCM allows encoding of voice signals in half the space PCM allows.
Annex D
A frame relay standard extension dealing with the communication and
signaling between customer premises and equipment and frame relay
network equipment for the purpose of querying network status
information.
Analog
The telephone transmission of voice, video or image. Telephone
transmission and/or switching that is not digital.
authentication
The process of identifying an individual, usually based on a username
and password combination, although the process can be many more
steps. In security systems, authentication is distinct from authorization,
which is the process of giving individuals access to system objects based
on their identity. Authentication merely ensures that the individual is
who he or she claims to be, but says nothing about the access rights of the
individual. Authentication in whatever form, is usually followed by
authorization.
