Section 3.3.4.1,p.53 says:

a)
|     The SDT Identifier is a 32-bit unsigned value which may only be
      significant to 12 or 14 bits depending on the SS7 variant which is
      supported by the MTP Level 3 at the ASP.  Insignificant SDT
      Identifier bits are coded 0.

b)
|     The SDL Identifier is a 32-bit unsigned value which may only be
      significant to 12 or 14 bits depending on the SS7 variant which
      is supported by the MTP Level 3 at the ASP.  Insignificant SDLI
      bits are coded 0.

It should say:

a)
|     The SDT Identifier is a 16-bit unsigned value which may only be
      significant to 12 or 14 bits depending on the SS7 variant which is
      supported by the MTP Level 3 at the ASP.  Insignificant SDT
      Identifier bits are coded 0.

b)
|     The SDL Identifier is a 16-bit unsigned value which may only be
      significant to 12 or 14 bits depending on the SS7 variant which
      is supported by the MTP Level 3 at the ASP.  Insignificant SDLI
      bits are coded 0.

Notes:

In both cases, the field width "32-bit" in the text does not match
the parameter breakdown in the immediately preceding artwork.
The above corrections are based on the assumption that the figures
are correct and the text is in error.
