UMERIC VECTOR PACKET
WN:
word number of vector (2 to 87 decimal) (Table 31).
WN describes the location of the vector word in the frame.
e:
error (Table 31). 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 31). This is the phase on which the vector
was found (0 = A, 1 = B, 2 = C and 3 = D).
K:
first check bits of the message checksum
(Table 31 and Section 8.8.6).
n:
number of message words in the message (Table 31),
including the second vector word for long addresses,
(000 = 1 word message, 001 = 2 word message, etc.).
For long addresses, the first message word is located in
the word location that immediately follows the associated
vector.
b:
word number of message start in the message field
(3 to 87 decimal) (Table 31). For long addresses, the word
number indicates the location of the second message
word.
x:
unused bits (Table 31). The value of these bits is not
guaranteed.
V:
vector type identifier (Table 32).
