advanced communication riser (ACR)

The Advanced Communication Riser (ACR) is an expansion bus for add-on cards for audio, network and Internet connections. The ACR riser was developed by several companies, including VIA and 3Com, and is compatible with the Audio Modem Riser

(AMR). However, not all of the ACR riser's 120 ports

are occupied, so its functionality is certainly expandable. One important functionality offered by the ACR riser expansion cards is xDSL communications, and the ACR specifications make it cheaper to install expansion cards for personal computers. The focus of these expansion cards is on audio and communication cards, such as the sound cards and modem cards.
