bit errors are detected (via BCH calculations, parity calculations, check character calculations, or
value validation) in the vector word the e bit will be set and the message words will not be sent.

Description
No special formatting of characters is specified

0 Special Format Numeric Vector
Formatting of the received characters is predetermined
by special rules in the host.

1 Numbered Numeric Vector
The received information has been numbered by the
service provider to indicate all messages have been
properly received
WN:
Word number of vector (2 - 87 decimal). Describes the location of the vector word in the
frame.
e:
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 on which the vector was found (0=a, 1=b, 2=c, 3=d)
K:
Beginning check bits of the message.
n:
Number of message words in the message 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 (3-87 decimal). For long addresses, the
word number indicates the location of the second message word.
x:
Unused bits. The value of these bits is not guaranteed.
