Decoder-to-Host Packet Descriptions

Roaming Decoder II

BLOCK INFORMATION WORD PACKET
The Block Information Field is the first field following the synchronization codes of the FLEX protocol. This field
contains information about the frame such as number of addresses and messages, information about current
time, the channel ID, channel attributes, etc. The first block information word of each phase is used internally to
the KS8701 and is never transmitted to the host with the exception of the system collapse which is sent to the
host when the KS8701 is in manual collapse mode.
Time block information words 2-4 can be optionally sent to the host by setting the
SBI
bit in the control packet
(see
“
Control Packet” on page 21). All block information words 2-4 can be optionally sent to the host by setting the
ABI
bit in the roaming control packet. When the
SBI
or
ABI
bit is set and any block information word 2-4 is
received with an uncorrectable number of bit errors, the KS8701 will send the block information word to the host
with the e bit set regardless of the value of the f field in the block information word. The KS8701 does not support
decoding of the vector and message words associated with the Data/System Message block info word (
f
=101).
The ID of a Block Information Word Packet is 0 (decimal).

e:
Set if more than 2 bit errors are detected in the word or if the check character calculation fails after
error correction has been performed.
p:
Phase on which the block information word was found (0=a, 1=b, 2=c, 3=d)
x:
Unused bits. The value of these bits is not guaranteed.
f:
Word Format Type. The value of these bits modify the meaning of the s bits in this packet as
described in the BIW word descriptions in the s bit definition below.
