100Base-TX
100Base-TX Also called "Fast Ethernet," it is a 100 Mbps version of Ethernet.
100Base-T transmits at 100 Mbps rather than 10 Mbps. Like regular
Ethernet, Fast Ethernet is a shared media LAN. All nodes share the 100
Mbps bandwidth. 100Base-TX uses two pairs of Category 5 cabling, one
pair for transmission, one pair for receiving.
analog The telephone transmission of voice, video or image. Telephone
transmission and/or switching that is not digital.
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.
Asynchronous
Transfer Mode Very high speed transmission technology. ATM is a high bandwidth,
low-delay, connection-oriented, packet-like switching and multiplexijng
technique. Usable capacity is segmented into 53-byte fixed-size cells,
consisting of header and information fields, allocated to services on
demand. The term "asynchronous" applies, as each cell is presented to
the network on a "start-stop" basis - in other words, asynchronously.
bandwidth The width of a communications channel. Analog is typically measured in
Hertz (cycles per second), a voice conversation is typically measured in
bits per second.
Bipolar 8-Zero
Substitution A coding scheme that maintains ones density.
bipolar violation BPV. A violation is declared for AMI if two successive pulses have the
same polarity.
Bit Contraction of the words "binary" and "digit".
Bit Error Rate The number of erred bits divided by the total number of bits.
Basic Rate
Interface Basic Rate Interface (2b+d) in ISDN.
