LC Events
For LC events, the event specifies a LC, and the event type field specifes what happened on the LC. The
following event types are defined:
ABR Events
The following events are used for ABR processing, and are routed to the receive queue specified in the ABR
event routing register.

Description
0x10=010000
AAL0 Cell was Dropped due to Lack of
Pools Buffers
This event specifies that a AAL0 (non-FIFO mode) cell was received,
but was discarded because no POOL buffers were available. The event
information contains a pointer to the LCD on which this cell was
received.
0x11=010001
AAL5 Cell was Dropped due to Lack of
Pools Buffers
This event specifies that the first AAL5 cell for a packet was received,
but was discarded because no POOL buffers were available. The event
information contains a pointer to the LCD on which this cell was
received.
0x12=010010
Non-user Data Cell was Dropped due to
Lack of Pools Buffers
This event specifies that a non-user data cell was received, but was dis-
carded because no POOL buffers were available. The event information
contains a pointer to the LCD on which this cell was received.
0x13=010011
Fifo Cell was Dropped because Fifo Full
This event specifies that a AAL0 (FIFO mode) cell was received, but
was discarded because the FIFO was full. The event information con-
tains a pointer to the LCD on which this cell was received.
0x14=010100
Fifo Threshold Occurred
This event specifies that the FIFO threshold has been crossed. The
event information contains a pointer to the LCD on which this threshold
occured.
0x15=010101
Fifo is Full
This event specifies that a FIFO has become full. The event information
contains a pointer to the LCD on which this timeout occured.
0x16=010110
Fifo has Timed Out
This event specifies that a reassembly timeout has occurred for a FIFO.
The event information contains a pointer to the LCD on which this time-
out occured.
0x17=010111
Reserved

0x18=011000
LC Total User Cells RX Counter Overflow
This event specifies that the TUC RX counter in the LCD has over-
flowed. The event information contains a pointer to the LCD.
0x19=011001
LC Total User Cells CLP=0 RX Counter
Overflow
This event specifies that the TUC w/CLP=0 RX counter in the LCD has
overflowed. The event information contains a pointer to the LCD.
0x1a=011010
LC Total User Cells TX Counter Overflow
This event specifies that the TUC TX counter in the LCD has over-
flowed. The event information contains a pointer to the LCD.
0x1b=011011
LC Total User Cells CLP=0 TX Counter
Overflow
This event specifies that the TUC w/CLP=0 TX counter in the LCD has
overflowed. The event information contains a pointer to the LCD.

0x2c=101100
ADTF Event
This event occurs when the TADTF timer (as set in the LCD) has
expired. The event information contains a pointer to the LCD.
0x2d=101101
CRM Event
This event occurs when CRM or more RM cells are sent without receiv-
ing a backward RM cell. The event information contains a pointer to the
LCD.
0x2e=101110
CCR = 0 Event
This event specifies that the current cell rate has been set to 0. The
event information contains a pointer to the LCD.
