Patch Panel Connections

[Nova-Security]

Having problems with telephones through a patch panel, this is what i have existing.

patch panel for all data sockets, and a seperate panel for telephone incoming lines so i can patch a line to any socket and use a mod-tap to convert to phone socket, this works, left the phone and the line is there but can get the phone to ring.

Does anybody know which terminal on a patch panel (rj 45 ) the ring leg goes pin 3 of a telephone socket.

Thanks

Can you explain a bit more what your problem is?

Analogue phones only use 2 wires to take a call and ring, via a master socket which filters out the ring signal to a third wire.

Have you got a "master" type adapter (mod-tap) not an extension one? This will sort out the correct signals for your phone.

If you're not sure look inside it (if you can). A master has some simple electical components (capacitor, etc.) but a slave/extension has none.

BT people please correct me.....................

Over my head this, give my a 300 zones intruder system anyday,

I have put in a patch panel to distribute our data and telephone services, in on patch panel it has the telephone lines in it, but i can get phones to ring when ringing in but you can make calls out on the phone, so i am missing a ring or something.

Sounds like you need a master mod-tap, or at least that's the easiest solution.

Usually, when wiring analogue phones through a modular wiring system they are only using one pair and are hanging off of a PABX, whereas the UK telephone wiring requires 3 wires to operate. Sticking a master mod-tap on the end of can make it work, but too many masters on the line can sometimes cause problems.

master socket feeds patch panel then i was going to have secondary mod-taps at various points, tried different ways of connecting but cant seem to get things working right.

Any ideas of what i should do.

You are nearly there !, BT line terminals 2 and 5 in the socket wire to terminals 4 (Blue) and 5 (white/blue) on the PatchPanel, this gives you your line. If using a standard analogue telephone, to make it ring you need to use a Master mod-tap.

Secondary Mod-taps are used for phones that do not require the bell signal wire such as System featurephones on a telephone system.

You should be ok with using lots of master mod-taps, too many can sometimes have an effect on ADSL-enabled etc, but have seem 4 or 5 used simultaneously mant times without a fault and even BT frequently wire in all masters if wiring is in place with only 1 pair free.
