Actually, the only link to 04.06 is a note in section 3.2 saying:

> LPD = "0 1" corresponds to the data link protocol used for SMSCB (see 3GPP TS 04.12).

... whereupon the LPD=01 address field variant is redefined to contain 
different bit-fields.  This supports the idea that implementation of 
SMSCB should be entirely separate from LAPDm.
