i am staying at my grandmothers place and am currently getting broadband with slingshot set up. my grandmother has one of those st john medical alarms, now i know it is standard practice to install a splitter but i was thinking, since the medical alarm would not be used when the broadband is being used is it really neccesary to fork out the $149 for a splitter? because the alram is only for when me and other family members go away and we cannot help her, and when we go away we could just turn off the modem. would this allow her to use her alarm? would the medical alarm being on effect the broadband connection when not in use?
thanks in advance
