3.3.1.5 Total Buffer Length
The size of the buffer will be determined by the Doppler, plesiochronous, and the frame
and multiframe length (the last three sections). Using the three examples given in the last
three sections, the total buffer depth (end to end) will be:
Doppler + Plesiochronous ms (rounded up to the nearest multiframe)
(e.g., 1.15 + 6.98 = 8.13 ms)
If the multiframe length is 2 ms, then the nearest multiframe will be 10 ms, or 20480 bits.
3.3.1.6 Converting
To convert bits to seconds:
1/Data Rate times Bits = Seconds
To convert seconds to bits:
Data Rate times Seconds = Bits
