SHORT MESSAGE/TONE-ONLY VECTOR PACKET

V: vector type identifier, these bits set to 010 for a

short message/tone-only vector (Table 33).

WN: word number of vector (2 to 87 decimal) (Table 33).

WN describes the location of the vector word in the frame.

e: error (Table 33). 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 33). This is the phase on which the vector

was found (0 = A, 1 = B,2=Cand3=D).

t: message type (Tables 33 and 34). These bits define the

meaning of the d bits in this packet.

x: unused bits (Table 33). The value of these bits is not

guaranteed.

d: data bits whose definition depends on the value of t in

this packet according to Table 34. Note that if this vector is

received on a long address and the e bit in this packet is

not set, the decoder sends a message packet from the

word location immediately following the vector packet.

Except for the short message on a non-network address

(t = 0), all messages bits in the message packet are

unused and should be ignored.

Table 34 Short message/tone-only vector deﬁnitions

Note

1. For long addresses, an extra 5 characters are sent in the message packet immediately following the vector packet.
