Cell Outlet Cell Available: The direction of the
COCLAV signal depends on the mode selected:
ATM Layer emulation: An active high input from the
PHY layer device to indicate that it can accept the
transfer of a complete cell. This applies to UTOPIA and
16-Bit modes
PHY Layer emulation: An active high output that the
CUBIT- Pro asserts to indicate that it can transfer a
complete cell to the ATM layer device. This applies to
UTOPIA and 16-Bit modes.
Back-to-Back mode: COCLAV is an active high output
signal.
ALI-25 mode: TdVal signal (output).
Cell Outlet Clock: Transfer clock. Rising edge of
COCLK is used for data transfer.
ATM Layer emulation: This is an output clock. This
applies to UTOPIA and 16-Bit modes.
PHY Layer emulation: This is an input clock. This
applies to UTOPIA, Back-to-Back, and 16-Bit modes.
ALI-25 mode: TBClk signal (input). Maximum clock
speed of 42 MHz with a 40/60 duty cycle.
output in ALI-25 mode.
Cell Outlet Enable: An active low enable signal which
occurs during clock cycles when COD(7-0) data and/or
COSOC are active.
ATM Layer emulation: An active low output signal. This
applies to UTOPIA and 16-Bit modes.
PHY Layer emulation: An active low input signal. This
applies to UTOPIA and 16-Bit modes.
Back-to-Back mode: COENB is an active low input sig-
nal.
ALI-25 mode: TLoad signal (input).
16-Bit modes. TDPrty parity output in ALI-25 mode.
Generic Flow Control: Inlet for GFC nibble to be
inserted at cell outlet.
Force ABR Congestion: Active high signal to force a
congestion indication for any ABR cells received.
Line Clock: Rising edge used for data transfer. This
clock input is used for the cell Inlet/Outlet timing
assuming that CLKS1,CLKS0=0,1 in register 0BH.
