Patch Panel Connections

[Guest]

OK, the other way then, if you're using secondary mod-taps, is to connect pin 3 of the master socket (white\orange) to pin 2 on the patch panel (orange) in addition to Simons connections.

If you've got master sockets that then feed the patch panels you've got to use slave/extension mod-taps to plug your phone cable into.

Best to get your multimeter out on the mod-taps and verify that they're wired up to carry the ring signal, and on which connector. Then just wire up the other end the same.

You need to check, I have come across secondary mod-taps where there is no connection to RJ45 Pin2 internally and hence the bell-wire is not passed. Best tyo check before rewiring it in.

And remember no more than 4 REN of each line as this will affect the Ringing cadesence any more than 4 will need a ring booster or equivalent

By the way, Mod-Tap is a manufacturer of all sorts of stuff and is now Molex.

To quote their web site:

"MOD-TAP (now known as Molex Premise Networks),"

The devices you want are actually called LAU's (Line Adapter Units).

Se, for example, these sold by Inmac. RJ45 to BT adapter

I wondered if anyone was going to mention the mod-tap\LAU thing!

Regarding the REN, most modern handsets are actually well under ! so you can quite easily go way past 4 and not suffer any problems. Just stop adding phones when they don't ring any more!

I agree lurch about the REN but you will be amazed how many faults I do a week regarding the REN. The worst offenders are Binatone, Samsung, and the Panasonic DECT types. Also allot of the older Phillips DECTs gave a lot of problems It also doesn

I wired a huge house recently, and installed a 48way patch panel. We also fitted a small (4-16) PBX, and patched this to the panel.

Direct lines from the NTE where patched to outlets aswell, using secondary modtaps.

I will try to find the numbers we used. We had a patchpanel wired with the RJ45's with the 16 exn's, and the direct lines, so these could be patched to the panels above.

But.. remember some telephones have a built-in capacitor so do not require the bell wire (whether is is passed through or not), seem to remember a lot of Interquartz phones have this.

It is definetly RJ45/Patchpanel terminal number 2 (orange) which cross connects the bell wire from terminal 3 in the LJU or direct from NTE5a. Just as long as the Mod-Tap/LAU supports it.
