TXCP Idle Cell Header Control
The CLP bit contains the eighth bit position of the fourth octet of the idle/unassigned cell
pattern. Cell rate decoupling is accomplished by transmitting idle cells when the TXCP
detects that no outstanding cells exist in the transmit FIFO.
The PTI[3:0] bits contains the fifth, sixth, and seventh bit positions of the fourth octet of the
idle/unassigned cell pattern. Idle cells are transmitted when the TXCP detects that no
outstanding cells exist in the transmit FIFO.
The GFC[3:0] bits contain the first, second, third, and fourth bit positions of the first octet
of the idle/unassigned cell pattern. Idle/unassigned cells are transmitted when the TXCP
detects that no outstanding cells exist in the transmit FIFO. The all zeros pattern is
transmitted in the VCI and VPI fields of the idle cell.
