The OmniSwitch's FCSM (frame-to-cell switching module) provides both a 622 Mbps SAR function -- rt-VBR (real-time variable bit rate, such as MPEG video) -- nrt-VBR (non-real-time variable bit rate, such as frame relay) -- ABR (available bit rate, such as PCs and other workstations with ATM interface cards) -- UBR (unspecified bit rate, such as LAN switches)
CBR (constant bit rate) -- rt-VBR (real-time variable bit rate, such as MPEG video) -- nrt-VBR (non-real-time variable bit rate, such as frame relay) -- ABR (available bit rate, such as PCs and other workstations with ATM interface cards) -- UBR (unspecified bit rate, such as LAN switches)
For example, CBR transmission is used to assure real-time transmission of audio signals, where data delay is unacceptable while rt-VBR transmission is appropriate to transmit moving images, where data volumes vary greatly.
