AAL5 Packet Events
For AAL5 packet events, the event specifies the packet buffer address, and the event type field specifies the
type of packet event. The following event types are defined:
Receive Queues (RXQUE)

0x00=0000000
0x0e=0001110 Normal AAL5 FIFO Packet Event
0x01=0000001

Name
This event specifies that an AAL5 packet was received and has passed all AAL5
protocol checks (CRC, length). The event information contains a pointer to the
packet.
This event specifies that an AAL5 FIFO packet was received and has passed all
AAL5 protocol checks (CRC, length,...). The event information contains a pointer
to the packet.
This event specifies that the AAL5 packet header threshold was exceeded as set
in the LCD. The event information contains a pointer to the packet header, and the
user can access up to the packet header threshold bytes of data.
This event specifies that an AAL5 packet was received and the AAL5 CRC is bad.
The event information contains either a pointer to the packet if receiving bad
frames, or a pointer to the LCD on which this packet was received.
This event specifies that a AAL5 packet was received and the AAL5 length field is
bad. For example, there is too much data or not enough, but typically the bad CRC
is detected first. The event information contains either a pointer to the packet if
receiving bad frames, or a pointer to the LCD on which this packet was received.
This event specifies that an AAL5 packet was received but the amount of data has
exceeded the maximum length as specified in the LCD or in the MSDU register.
The event information contains either a pointer to the packet if receiving bad
frames, or a pointer to the LCD on which this packet was received.
This event specifies that a reassembly timeout has occurred for an AAL5 packet
that was being reassembled. The event information contains either a pointer to the
packet if receiving bad frames, or a pointer to the LCD on which this packet was
received.
This event specifies that an AAL5 packet was terminated with a forward abort. The
event information contains either a pointer to the packet if receiving bad frames, or
a pointer to the LCD on which this packet was received.
This event specifies that a AAL5 packet was received and the AAL5 CPI field was
not set to ’0’ which is an AAL5 protocol violation. The event information contains
either a pointer to the packet if receiving bad frames, or a pointer to the LCD on
which this packet was received.
