  Integrable multi-component lattice equations of the Boussinesq family have
been known for some time. Recently some new equations of this type were found
using the Consistency-Around-the-Cube approach. Here we investigate one of
these models, B-2, and in particular the consequences of a nonzero deformation
parameter $b_0>0$, which allows special kinds of solitons in the parameter
range $-b_0/3<k<b_0$.
