Info on Alcatel Femtocells

 Hi,
little UP:

Vodafone UK and other OpCo like it (VF DE and VF GR I think) made a local
femtocell network based on similar platform from ALU.

Does anyone know something/ever tried to make something like connecting one
of these devs to osmoHNBGW or similar?
Thank you and best regards
