ACR The difference between attenuation and crosstalk , measured in dB, at a given frequency (acronym for Attenuation CrossTalk Ratio). Important characteristics in networking transmission to assure that signals sent down a twisted pair are stronger at the receiving end of the cable than the noise signals imposed on that same pair by crosstalk from other pairs.
American Wire Gauge(AWG) A standard for expressing wire diameter. As the AWG number gets smaller, the wire diameter gets larger.
Amplitude The maximum value of a varying wave form
ANSI AMerican National Standards Institute
ASTM The American Society for Testing and Materials, a standards organization which suggests test methods, definitions and practices.
Asynchronous Transfer Mode The SONET standard for a packet switching technique which uses packets of a fixed length.
ATM See Asynchronous Transfer Mode
Attenuation The decrease in magnitude of a signal as it travels through any transmitting medium, such as a cable or circuitry. Attenuation is measured as the logarithm of a ratio. It is expressed in decibels or dB.
