Hi guys,

I'm trying to tidy up some wiring for a friend of mine who has about 6 devices currently connected to one phone jack. He's got a double adapter and two triple adapters to do this. Instead, we were going to install a 10 port patch panel and build it in to the wall to tidy things up a bit.

However, when the line is split into 10, there is a huge amount of static on the line. Is there any way to reduce this (by adding some kind of component perhaps?)

Thanks in advance! :)

Will

You do realise 6 devices probably exceeds the REN value of the phoneline? If you exceed the REN value you will encounter issues.

Does the static occur when the devices are plugged in or when they're not plugged in?

Why does he need 6 devices connected, it sounds a bit odd...

WTF is he running there, a taxi company or a brothel :)

It's a taxi brothel service.

With all devices connected using the double/triple adapters, there is no issue. When I try to split the line into several jacks (wired in parallel or series), the static occurs (with our without all devices connected).

And yes, I know it's stupid. Personally, I'd rather use the "if it ain't broken, don't fix it" philosophy...

Wire it into a CAT5e multitap and use ethernet cable and switches instead :)

Are you using proper 2 wire jacks and proper cat-something phone cable, without leaving any of the old wiring connected?

Static can be unfiltered adsl or else just a crap connection.

And what are the 6 devices. I can only really think of a reason for a couple - dect base, and a wired phone for power cuts.

Unfortunately it's in an apartment building so I can't easily get new cable back to the demarc point, but the cable coming up is Cat5E. That's then connected to a "cat3 rated" (

) voice patch panel, and from there cat6 was used to wire the other ports in series. Also tried to join the cables and run in parallel instead (using gel-filled joiners) but still no go.

The six devices (note, there is no ADSL on this line):

1) Fax (used for outgoing faxes)
2) Fax modem (used for incoming faxes)
3) DECT base
4) Wired phone
5) Eftpos machine (used for processing CC transactions)
6) Sky decoder (which could really just be disconnected...)

Get rid of the sky decoders connection for starters. Unless he uses lots of pay per view but its just as easy to do it over the phone yourself.
