hey there,

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

Hi Cully, its more a matter of the alarm being removed from the line, not just turned off. Also the alarm will seize the and drop it from passing onto the remainder of the house. The only real workable solution is to install a central splitter.

hey,

i wouldnt mind the central splitter the only problem really is that she is on the verge of canceling the medical alarm and i dont wanna have to pay $149 only for her to cancel it next week.

anyway, can i have the broadband connected but the modem unplugged and off and use the medical alarm ok? or do the dsl signals on the line stop the alarm form working?

Its the alarm that can cause issues with the DSL modem, not the other way around. This can be in two ways, firstly the line goes to the alarm and then out to the rest of the house wiring so that the alarm can seize the line, often these alarms have no regard for anything above the voice band so often effect the DSL signal, and secondly the alarm from time to time can seize the line just to check its working, this will drop all lines downstream including the DSL modem, so it looses sync.

So if its working OK for now just leave it all connected up.
