The difference between attenuation and crosstalk, measured in dB, at a given frequency (acronym for Attenuation Crosstalk Ratio) Important characteristic in networking transmission to assure that signal sent down a twisted pair is stronger at the receiving end of the cable than are any interference signals imposed on that same pair by crosstalk from other pairs
Audio Communications Riser, a slot that is only used by large OEMs to add cheap devices to their computers Since ACR devices are software based, they often times sap a lot of CPU resources
Allowed (or Available) Cell Rate (ATM) The available bandwidth, in cells per second, for a given QoS class, which is dynamically controlled by the network
Attenuation to Crosstalk Ratio: One of the factors that limits the distance a signal may be sent through a given media ACR is the ratio of the power of the received signal, attenuated by the media, over the power of the NEXT crosstalk from the local transmitter, usually expressed in decibels (db) To achieve a desired bit error rate, the received signal power must usually be several times larger than the NEXT power or plus several db Increasing a marginal ACR may decrease the bit error rate
Attenuation Crosstalk Ratio The value of attenuation, less the crosstalk value, both expressed in dB, at a particular frequency A quality factor for cabling that expresses the relation of two important measured values (See also S/N )
Parameter defined by the ATM Forum for ATM traffic management ACR varies between the MCR and the PCR, and is dynamically controlled using congestion control mechanisms
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
