Flush Pending Packet. When ‘1’, pending packets will be sent in a zero padded cell
before this packet is sent. When ‘0’, normal TX CPS processing will be done to try
to maximize bandwidth utilization.
TDM Write Pointer used to write xxPCM samples in the TX Circular Buffers at the
time of the generation of this event.
Size of the HDLC circular buffer in which the HDLC packet is contained.
Length of the payload of the HDLC packet in bytes. This length includes the UUI
field with is contained the first byte of the packet. Thus the AAL2 LI will be equal to
this field minus 2.
Number of the HDLC Stream structure in the TX TDM Control memory that
generated this event structure.
Base address of the Tx RTP Connection Structure to which this event is being
sent. The base address is pointed to in increments of 64 bytes.
Start bit. When this bit is set, the first packet of an xxPCM channel can be sent. If
an event is received by an TX Connection structure with xxPCM channel waiting
to startup (i.e. I bit is cleared), only events with the ST bit set will allow the first
packet to be sent out (other event will be ignored).
TDM Write Pointer used to write xxPCM samples in the TX Circular Buffers at the
time of the generation of this event.
Local Bus Time Stamp during which the HDLC packet completed.
