The users data rate of a satellite channel is expressed in Bits per second; Bps,
Kilo[Thousand]bits per second; kBps, or Mega[Million]bits per second; Mbps.
The rate of a satellite delivered data channel is measured in sps or symbols per
second, see the table above for a comparison of Bps-to-Sps. An MCPC or Digital Video link would typically run at several Mbps, Video conferencing @ 384kBps, Audio @ 192 – 256 kBps and Data and Voice circuits @ 64kBps [or multiples thereof].
