The minimum buffer size is determined by the the number of bits in the frame and the maximum
buffer size is based upon the integral number of frames that can fit in the buffer memory.
If Intfc1 Port1 Rx Buffer:
Intfc1 Port1 Rx Buffer:
10.0 mSec (0344.064 Bits)
The Rx Buffer is programmed in 0.5 ms steps rounded to the increment closest to an integral
number of bits based upon the Frame Type.
The maximum buffer size is:
61 ms;
G.751
The Rx buffer has a minimum value of 0.5 ms (default). Selecting the minimum value and
programming Rx-CLK for Rx-SAT disables the buffer and sets it to minimum.
