Ready for a non-comittal answer?? /forums/images/graemlins/tongue.gif /forums/images/graemlins/wink.gif

Simply stated, until you get it, you really won't know for sure. Some folks get dern near what the telco's promise, some don't get anywhere near that.

You can get a "feel" for what type of speed you will get by going to DSL Reports - Speed Test , running the test, then at the bottom, adding your results to the database, going to the next page to "review others" and then typing in your zip.

Kindof a round-about way, but better than nothing. PLEASE NOTE: Although this may give you a "feel" it is FAR from certain due to the different pieces of equipment others may be hitting compared to the pieces you'll be hitting once you have your xDSL up and running.

I agree - I wasn't recommending using such a device, just trying to explain (in principle) the connectivity model using the items KubotaSteve mentioned. Talking to a couple of different audiences here in this thread I suppose - which can make things a bit muddled at times.

I am familiar with the concept demarcation points - and although my "quickie" diagram didn't label the anything as such, it is in there.

I agree with your point that there are too many possible combinations of wiring, equipment layouts, etc. to illustrate all possibilities - but I really wasn't trying to do that - really just trying to illustrate the question I had regarding if a single filter/splitter would work for multiple POTS instruments and thereby eliminate the costs associated with having to buy multiple filters.

BTW, thanks for confirming my understanding on how the filter worked.

DSL Filters for $1.50 each unless you want 100 then they're $1.00 each

Bill_K -

Thanks for the info. You have raised my curiosity a bit with regards to the multiple filter aspect...

Specifically, I have 3 questions:

1) How do the extra filters hurt the signal which causes a reduction in speed (attenuation??)

2) Do they cause problems even if the voice instruments aren't off-hook?

3) Are the limits regarding # of filters standard or are they developed by the LEC for their specific implementation of xDSL?

Tnx! /forums/images/graemlins/laugh.gif

Ranchman, I have DSL and no filters on the phones. I get no interference whatsoever from the DSL. My package came with filters, (at no cost) but I had no need for them. If I'd known they were worth $20/ea I wouldn't have given them back to the phone co when they stopped at the house to check on the install.

Went by the telephone office this afternoon to sign up. It said on the app the maximum speed would be 384kbs. They won't guarantee what I'll actually get.

Oh well. Still has to be better than what I have now.

Billy I use it and feel I have had good luck with it. I haven't experienced many other systems to know the difference. It sure does beat the old 56K modem!

Most DSL systems that I have seen are dual speed, a high speed for downloads and a lower speed for uploads. Since most home users rarely ever upload this is acceptable, unless you are running your own web site hosted by the ISP.

Re: upload/download speeds.

Almost all are this way. You are not supposed to be running web servers off of it, and this is one way to make sure that if you do, it won't handle much traffic.
