Verizon DSL Filters ?


Hello:
Regarding those Verizon DSL filters that are supposed to be installed at each phone jack.
No problem putting them in place, but was curious about just what they are filtering.
Are they high pass or low pass filters ?
What gets through ? The phone ring and the conversation I guess, but not the digital (high) frequencies ?
What is the effect if you don't have one in place ?

If you don't put them in place your conversations will sound extra crappy. The filters are there to filter out the modem communications - if you're not online you won't hear the static on the line.
Think of it this way, when you pick up the receiver and someone is already on the line - what you hear is their conversation. If your computer is dialed in and you pick up the receiver what you hear is the computer "talking". The filters remove the computer's conversation from the line YOU'RE on.

They are low pass filters and block the higher frequency signals for DSL. Take one off and you will hear a hiss on the phone. Without them the DSL signal is weaker since some of it is going into the phone.

better operation if you install a single filter at the NID or just indoors with a single line for the computer.
My speeds improved a LOT with the central filter and less junk on phones you no longer need filters at each phone

If you put a filter at the jack where the computer is you won't be able to get online. The filter removes the communication between the modem and the hub. That's how the Qwest filters worked anyway. So centrally locating the filter would block out all the signals coming from the modem. It's possible that Verizon is using a different mechanism for filtering their signals. But as Jeff keeps harping on, they really are just simple frequency filters

Okay I see what you're saying.
BTW and totally OT, but I since migrating to Vista I noticed that Microsoft Mail won't put the ">" characters in front of the replied to text like the previous version did. It makes it really tough to follow a conversation unless you add them in yourself.
