unshielded twisted
-
pair wiring.
AMI

 ANSI

asynchronous
A method of data transmission which allows characters to be sent at irregular 
intervals by preceding each character with a start bit, followed by a stop bit.
bandwidth
The bandwidth determines the rate at which information can be sent through a 
channel (the greater the bandwidth, the more information that can be sent in a 
given amount of time).
baud rate
A measure of transmission speed over an analog phone line. Baud rate measures 
the shortest signaling elements per second in the analog signal that a modem 
sends over an analog phone line. Does not necessarily equal the bit rate.
