CLP

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-50

detects that no outstanding cells exist in the transmit FIFO.

PTI[3:0]

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-50 detects that no

outstanding cells exist in the transmit FIFO.

GFC[3:0]

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-50

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.
