* -- It is composed of -- a) one octet for type of subaddress and odd/even indicator. -- b) 20 octets for subaddress
* information.
*
* -- a) The first octet includes a one bit extension indicator, a -- 3 bits type of subaddress and a one bit odd/even
* indicator, -- encoded as follows:
*
* -- bit 8: 1 (no extension)
*
* -- bits 765: type of subaddress -- 000 NSAP (X.213/ISO 8348 AD2) -- 010 User Specified -- All other values are reserved
*
* -- bit 4: odd/even indicator -- 0 even number of address signals -- 1 odd number of address signals -- The odd/even
* indicator is used when the type of subaddress -- is "user specified" and the coding is BCD.
*
* -- bits 321: 000 (unused)
*
* -- b) Subaddress information. -- The NSAP X.213/ISO8348AD2 address shall be formatted as specified -- by octet 4 which
* contains the Authority and Format Identifier -- (AFI). The encoding is made according to the "preferred binary --
* encoding" as defined in X.213/ISO834AD2. For the definition -- of this type of subaddress, see ITU-T Rec I.334.
*
* -- For User-specific subaddress, this field is encoded according -- to the user specification, subject to a maximum
* length of 20 -- octets. When interworking with X.25 networks BCD coding should -- be applied.
