    ONLY VECTOR PACKET
    V:
    vector type identifier, these bits set to 010 for a
    short message/tone-only vector (Table 42).
    WN:
    word number of vector (2 to 87 decimal) (Table 42).
    WN describes the location of the vector word in the frame.
    e:
    error (Table 42). 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 42). This is the phase on which the vector
    was found (0 = A, 1 = B, 2 = C and 3 = D).
    t:
    message type (Tables 42 and 43). These bits define the
    meaning of the d bits in this packet.
    x:
    unused bits (Table 42). 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 43. 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 42
    Short message/tone-only vector packet bit assignments
    Table 43
    Short message/tone-only vector definitions; note 1
    Notes
    1.
    When this vector is sent in conjunction with a Network Address, the t
    1
    ,t
    o
    value ‘00’ represents Network ID information.
    In this case the bit definitions are: T3 T2 T1 T0 M2 M1 M0 A4 A3 A2 A1 A0
    Where T are Traffic Management Flags, M represents a multiplier and A is the service area.
    For long addresses, an extra 5 characters are sent in the message packet immediately following the vector packet.
    t
    0
    and t
    1
    are also set to ‘00’ when defining the last 12 bits of a Network Address.
