MESSAGE VECTORS
V:
vector type identifier (Table 44).
WN:
word number of vector (2 to 87 decimal) (Table 45).
WN describes the location of the vector word in the frame.
e:
error (Table 45). Set if more than 2-bit errors are
detected in the word, if the check character calculation fails
after error correction has been performed, or if the vector
value is determined to be invalid.
p:
phase (Table 45). This is the phase on which the vector
was found (0 = A, 1 = B, 2 = C and 3 = D).
n:
number of message words in this frame (Table 45),
including the first message word that immediately follows
a long address vector. Valid values are 1 to 85 decimal.
b:
word number of message start in the message field
(Table 45). Valid values are 3 to 87 decimal.
x:
unused bits (Table 45). The value of these bits is not
guaranteed.
Note that for long addresses, the first message packet is
sent from the word location immediately following the word
location of the vector packet. The b bits indicate the
second message word in the message field if one exists.
