ISPs installing the required bits to make a system intercept-ready is 
actually interception under 2(2)(a), "modifies", even if it's not 
switched on - but it isn't illegal because of the SI and perhaps some 
other enactments, and s.3(3)(b).

Only using them, unauthorised, is illegal.

Using it to send content is a second interception under 2(2)(a), 
"modifies". and is only legal if there is a warrant for that content.

Sending any other content - even if goes to a box which is switched off, 
as long as the switch is in someone else's control - is illegal 
interception by the ISP, again under 2(2)(a), as it makes content 
available to the someone else who controls the switch.


If GCHQ or whoever switch the box on on without a warrant, they are 
arguably [*] intercepting under 2(2)(a), and unless there is a warrant 
it is also illegal under 2(2)(b) "monitors".

[*] it depends whether the box is considered part of the telecomms 
system or not.
