Question
Wiring diagram for 2 different phone (numbers) to share one Telephone cable (RJ11 Splitter).
We are hiring more new staff and each staff gets a individual phone number. However there is not enought structured cabling points for voice lines. I am trying to search for RJ11 (telephone) cable splitter such as those available for RJ45 but I am not able to find any (see URLs below).
Does anyone know the wiring scheme for making such a splitter cable? Then I can ask the cable shop to make a pair of these cable splitter / combiner .
Thanks
Joo

Hi,
Actually the picture I attached may be misleading. The picture of the RJ45 splitter actually allows two PC to share one CAT5 underfloor cable. Each PC / LAN card only uses 2 pairs of wire but the CAT5 has 4 pairs of wire so it allows 2 PCs (from user office area) to share one CAT5 cable to the hub in the cabling room.
I need the same for telephone points - each telephone will have its own line i.e. not a shared phone connection (Y-spllitter).
Thanks
Joo
Do you mean something like these?
http://www.omnicronelectro
http://www.amazon.com/AT-T
NOTE: This is RJ14
Yes, like the Omnicronelectrics.com except it needs to be RJ11 instead of RJ14.
Not the Amazon example because that is a normal Y splitter (two phones sharing the same line).
In the underfloor CAt3 cable, there are 2 pairs of wires but a telephone will only use one pair, so with a splitter, two phones can each use one pair of the CAT3 underfloor cable.
From our wiring room we will have two telephone lines from Singtel, the two RJ11 will be combined into one RJ11 male jack connected to the patch panel.
From Patch Panel to floorbox there is only one CAT3 cable, we will use the cable splitter at the floorbox end to allow two phones to hookup (each will have a seperate phone number).
Cheers
Joo
No, you've misread the Omnicronelectrics.com example. It splits 1x RJ-14 outlet to 2x RJ-11 lines. I guessed this is hat you wanted? But to use them, the existing wiring scheme used for your outlets should be twin-pair (four wires per outlet).
If your existing outlets are wired for single UTP (two wires), then you can't use it for two individual lines without using rf-splitters. rf-splitters can split a line into several voice lines (alas, no data).
Here's another good splitter:

Make sure you phone system only uses 1 pair, some use 2 pairs. Also though the wall jack has 4 pins, did the installer connect all 4, it is common for them to only connect 2 if that is all they need.
The better/tidier way to do this is change your modular wall plates to one that houses an additional jack and change the cabling behind.(available in 1 to 8 with phone/Ethernet/cable combos)
