RE: [OT ish] ADSL Filter / ADSL Modem

["Keith Doxey" <ukha@xxxxxxx>]

For a BT installed ADSL there  will be a filter in the Linebox that will filter the ADSL carrier from ALL phones in the house.

 

As I understand "WIRES ONLY ADSL" to be, BT supply you the ADSL service by jumpering up the line in the local exchange but do not visit the premises. As they do not visit there is no filter, hence the term "WIRES ONLY".

 

This means that the ADSL carrier will appear at all sockets in the house therefore each phone will require a filter, as Ian said in his original post, he has Comfort and a PBX therefore all his phones are fed from a single point on the BT line. If he fits a filter before Comfort it should work OK and filter all the phones in one hit.

 

I stand by my original statement that for a normally wired house where ALL the phone sockets are connected to the line you would need to filter each phone individually ( but you would be able to plug the ADSL modem in wherever you wanted as the carrier would be everywhere).

 

Ian does not need individual filters provided he filters the line before Comfort.

 

The above comments are based on my work with other carrier based systems as I cant yet have ADSL.

 

Did have some slightly good news yesterday...... the nearest ADSL enabled exchange is only 20 miles from me rather than the 50 miles it was before christmas. Things are looking up....SLOWLY :-(

Keith,

 

Are you sure thats neccessary ?

 

With either BT's replacement splitter faceplate or a DIY plug in splitter you can still wire extensions to the removable section of the master BT box. My comfort & PBX work this way and i fail to see why any number of extension in parallel wouldn't.

If all your phones are fed from Comfort via a PBX then you "effectively" only have one phone plugged into the line ( the point where you take it to comfort). Therefore fitting a filter there will filter all the phones.

 

That statement ( as I read it) is for "normal" people who's line would come into the house and feed every socket. Therefore every socket would need filtering.

Hi

 

It appears with the self install ADSL you need to plug in an ADSL filter at each phone point in use.

 

What I am looking for is a 1 gang mount unit that will split the phone line and ADSL at node 0. I can then feed the phone straight into comfort and onto a PBX and the ADSL straight into the modem. I know I could buy the normal plug in type and wire the two o/p's back to were I want them but it will look messy. Anyone know were I buy such a thing ?

 

I use Winroute on my server to control the network so I only need a ADSL modem, no need for hub, router built in etc what would anyone recommend or do I buy one with everything build in and disable the extra functions for now. I'm looking for a modem that will plug into a second NIC on the server. Any thoughts Folks ?
