Just had another thought. I have a security system that when tripped calls back to the alarm company. I spoke with a tech at the alarm company this morning. He said that once I get DSL installed, I should trip the system. If it reports back, then I'll be okay but if not, he would send me a special filter.
This seemed like a good plan; However, he then indicated that sometimes, even if the system is able to report back, since it is unfiltered, it can cause problems with DSL performance. is this the case? Will the alarm system cause interference even when it isn't actively using the phone? If so, then it would seem that my best bet would be to ask him to send the filter even if things appear to be working fine?
Any thoughts much appreciated,
