Why does phone need dsl filter

theres some thing wrong with the base unit, try unplugging it and plugging the whole setup at a friends or something, also if youhave a DSL line you my have to install a filter to seperate the data line and voice line. Its ole school but this might work.

Hello,
Do you have ADSL internet in your new place? If so you will need an ADSL filter plugged into the phone outlet and plugged into your fax machine. so it would look like phone wall jack--->filter-->fax machine.
ADSL internet creates it own jabber or digital noise in the line and the filter will stop your a analog device from hearing the noise. If you don't have a filter for your phone as well, you should get one. Without filters your ADSL internet will be slower as well. Your ADSL modem should have came with at least 4 filters, if not they can be purchased at your local Bestbuy, staples or computer place. NOTE: Filters only work if you have ADSL or DSL internet.
If you do not have ADSL or DSL internet and still have noise you may have to call your phone service provider to get them to diagnose your line issues. They can fix some noise issues from their end.

This is odd behavior; have you tried moving your DSL modem to a different phone outlet in the house? If you do so, make sure to move the filters around appropriately as well; the only type of filter the DSL modem should be connected to are the "Y" type filter that has a "DSL" port as well as a "phone" port.

Do you have an alarm system? If so, it will need a filter too. Try contacting your alarm company and asking them if the system has a filter installed. If they don't know, try to get inside the control box (the large metal box, not the keypad) and see if there's a filter installed - it should look pretty similar to a regular phone line filter.

If you don't see one, ask your alarm company if you can install it yourself and how to do so, or ask that they install one for you. Be aware though, they may try to charge for a technician dispatch; if the alarm system was installed after you got DSL, insist that they do it free of charge, as the installation technician should've asked whether you had DSL and installed a filter at the time of the alarm installation.

Also, I might suggest trying to disconnect all phones in the house (at the wall jacks), and then call your home phone from a cell phone and see if you still get disconnected. If you don't, try connecting one phone at a time and repeating this test until you do get disconnected.

At that point, try unplugging all the other phones except the last one you reconnected and test again. If it disconnects when you call, then this phone or its filter is your problem; if it doesn't disconnect, it may have to do with the number of devices attached to your line.

If you've narrowed it down to a single phone/device that is causing the issue, try swapping that device's line filter with another phone's filter that previously tested okay, and plug only the problem device in with the new filter - if your connection stays up when you call, you've got a shorted filter that needs to be replaced. If your connection still drops, there's something with that particular device that's causing issues; you may have to call the manufacturer of the device and see if they've had reports of similar problems.

If there is a filter on BOTH ends of the phone line that is the problem. There should only be one plugged into the wall. Take the phone line and plug it into the phone side of the filter. The end that plugs into your receiver should never have a filter on it. Also I've never heard of a receiver needing to be connected to a phone line AND a router. You usually only need one or the other but not both.

Replace the DSL filter. it is needed to in order to prevent interference between phones and DSL service operating on the same line. Without the installation of DSL filters, high-frequency signals or echoes from analog devices can result in reduced performance and connection problems with DSL service, and the high-frequency signals from the DSL service can result in line noise and other issues for analog devices.

There you go. Stop by Radio Shack and pick up a DSL filter and hook it up to the wall outlet of your fax machine. If the DSL modem is next to your fax machine, plug the fax machine into the outlet marked as phone.

I just got done doing this to both of my offices. Typically the phone company will use your fax line to piggyback the DSL. All you have to do is make sure your DSL modem output goes to the fax line either through the wiring block in your office or directly to the back of the modem itself.

That way you won't need the filter.

it sounds like you may not have any dial tone. the hiss [white noise] you are hearing is from the dsl modem.try plugging a regular corded phone into the jack to check for dial tone.if there is none,call your phone company.also try plugging the fax machine into another jack where you know there is dial tone.
good luck

i think when you purchased the 2wire modem it usually comes along with 3 sets of single port dsl line filters, try out those other filters see which one works. if the local network light doesn't come on, (are you using 2wire 1000 series?), check the network adapters in your computer, this usually happens when you are using lower versions of OS. try the power outlet in the kitchen / bathroom, if power light doesn't come on, push the reset button for 30 secs. if power light is still off or red, then you may need to replace the modem (check if it's still under warranty, if not you will need to buy a new one.) also you should be using the same power adapter that came with the modem, check the specs. sometimes if the modem is more or less than 3 years old, they could get defective especially if it's often affected by sudden power surges.

Your Nortel M7208 phone is plugged into your Norstar phone system (not the phone line) You would not be able to use DSL on the same phone port used by the M7208 phone. A filter connected to that port would not solve a DSL issue and could only cause problems with the M7208 phone. You may need to put the filter on the phone lines before they connect to the Nortel phone system... I don't know which system you have or how it is wired up so I am not sure how easy that would be for you.

DSL line. Possible that filters are not plugged in. When DSL service is being used on your line, filters must be installed at every jack that is in use. The DSL signal can cause static/noise, squealing (similar to fax tones) and other issues on your line. (ex. Caller ID problems). In order to avoid having this issue, the service provider gives DSL filters to all customers when they sign up for service. These microfilters must be used because they allow your phones to work properly by blocking the high frequency DSL signals from being transmitted through the telephones. DSL filters should be plugged into EVERY phone jack that has a phone. If you are not using the filters provided by the telephone company, this will cause static/noise and possibly Caller ID issues on your phones that are plugged into jacks without filters. Please contact your service provider for filter information and proper installation. Interference: Other 2.4 GHz products. Other products that use the 2.4 GHz band can interfere with the use of this phone. Items include: Radio towers, pager towers, cell phones, other 2.4GHz cordless phones and 2.4 GHz intercoms or monitors. If any of these items are in the area, they can interfere with the performance of this phone; try relocating the phone. Other 5.8 GHz products. Other products that use the 5.8 GHz band such as home networking (wireless modems) other 5.8 GHz cordless products (phones etc.) can interfere with the use of this phone. Try relocating the phone. Interference from microwave. Microwaves work on the same frequencies as the 2.4 GHz phones. If the unit is on when the microwave is running, it is normal to experience static at that time. Do not plug this phone in the same outlet or near the microwave. Environmental. Normal radio operation. There may be places within your environment that a cordless phone will not work well. If the problem only occurs in certain areas of your environment, there is nothing wrong with the phone. Try channing channels. Surge protector or modem. Unplug modem or surge protector that is connected to the unit. Building structure limits range. Relocate telephone base near window when using telephone outside. Base unit located in basement or other low area. Relocate telephone base to higher location. The unit will get better reception if it is not located in a low area. Video displays, television sets and personal computers may cause interference. Video displays, television sets and personal computers can cause interference on this phone. Please relocate the phone to an AC outlet were there is no major appliance plugged in. If the base is near any of the above mentioned, locate the base to another room. Possible telephone line/service problem. Try using your equipment at a different location (i.e. friend or neighbors). If the unit functions properly in the new location, contact your local telephone company for assistance; additional charges to be incurred by customer may apply.
