  10. 13. Provisioning Video Data Rate + 20% = Bandwidth Required 128kbps = 153kbps 384kbps = 460kbps 512kbps = 614kbps 768kbps = 921kbps 1.5Mbps = 1.8Mbps < 33% of Link Capacity < 75% of Link Capacity Link Capacity Video Data Rate BW Required Beware – Video conferencing endpoints request 2 x the actual conference rate, so 384k conference yields request for 768kbps, and actually consumes 460kbps Link Capacity = ( Min BW for Video + Min BW for Data) / 0.75 Video Video Control Data Routing etc.
