Thats wrong. I assume you mean across the A and B screw terminals.
Firstly nothing should be connected across the line - thats BT property.
Secondly, the bell will be short circuiting the line and dropping the
ADSL signal level. Also one leg of the ADSL signal will be extended
outside causing unbalance.
Any telephone equipment should be connected via the 'phone' side of a
filter.
In your case that sounds difficult as the wire to the outside won't have
a BT plug on it to plug into a filter.
Ideally you should install a filtered faceplate with the bell connected
to terminals 3 & 5 at the rear of the faceplate.
Alternatively get an old BT phone cord and connect the bell between the
white and green wires and plug it into the filter. It must be a decent
quality filter with a 'ring capacitor' inside. A £10 ish one.
You may have to experiment slightly as, if the incoming pair is the
wrong way round, the bell may have to be on the wrong leg.
I know you shouldn't be touching it but the -ve 48v leg should be
connected to the B screw terminal (Battery on B)
