marks bit 7 of the CFI time slot called TSN according to the following formula:
CTAR:TSN6 … 0 = TSN + 2
e.g. CTAR must be set to 02
= 0). See examples.
Note that the value of TSN may not exceed the actual number of time slots per CFI
frame:
TSN = [ – 2; I – 3], I = total number of time slots per CFI frame
From the zero offset bit position (CBSR = 20
upstream) can be shifted by up to 5 bits to the left (within the time slot
number TSN programmed in CTAR) and by up to 2 bits to the right (within the previous
time slot N – 1) by programming the CBSR:CDS2 … 0 bits:

The bit shift programmed to CBSR:CDS2 … 0 affects both the upstream and
downstream frame position in the same way.
If CBSR:CUS3 … 0 = 0000, the upstream frame is aligned to the downstream frame.
With CBSR:CUS3 … 0 = 0001 to 1111, the upstream CFI frame can be shifted relative
to the downstream frame by up to 15 bits to the left as indicated in figure 41.
