CHAPTER 5 SAR FUNCTION
205
PACKET SIZE
Receive packet size.
The receive packet size is given either in cell units or in the Length value,
either of which is selected by setting the PSM bit of the GMR register.
PSM = 1: The PACKET SIZE field contains the same value as that in the
AAL-5 trailer Length field. It is the user data length of AAL-5
PDU, in byte units.
PSM = 0: The PACKET SIZE field indicates the size of the receive packet
(including the AAL-5 trailer), in cell units.
For an indication to report an error or an early receive indication, the
receive packet size is given in cell units even when the PSM bit is set to 1.
TIME STAMP
Value of TSR register when this packet was received
PACKET START ADDRESS
Start address of the used batch
CHANNEL
VC NUMBER or VPI/VCI value.
Stores the VC NUMBER or VPI/VCI value of the channel that was used to
received this packet. This mode is set with the CIM bit of the VC table for
each receive VC. Also, the CIM bit of the indication is used to post
notification of which value is to be stored.
CIM = 1: The VPI/VCI value, the length of which has been reduced to 16
bits using the VRR register, is stored into the field.
CIM = 0: The VC NUMBER of the channel on which this packet was
received is stored in bits 16 to 30. Bit 31 is set to 0.
ST
Status indication.
1: The indication status field contains a value other than 0 (normal).
0: The indication status field contains 0 (normal).
CI
Congestion indication.
Indicates that at least one of the cells belonging to this packet has arrived
with a congestion code in the PTI field of the header.
CLP
CLP = 1.
Indicates that at least one of the cells belonging to this packet has arrived
with the CLP field in the header set to "1."
