Hello everyone, I would like some help with wiring our Mitel 3300 MX on the back of our controller we have a Paging/Contacts port and all the documentation we have located shows the wiring as:

Number     Signal
1          Common contact
2          Normally closed contact
3          Normally open contact
4          Page1 (Tip)
5          Page2 (Ring)
6          No connection
7          Not used
8          Not used

Note: The Paging port is an 8-pin RJ-45 connector on the rear panel of the MX controller. The paging
port has a tip/ring pair for audio and contact closures for zone control. The normally closed contact
opens when paging and the normally open contact closes when paging.


But when I wire into pair 4,5 I hear the hold music coming from our external device. Can anyone help me with how i should wire this up and if any changes need to be made on the controller to output the pages to the port on the back?

if you refer to this thread paterson explains a bit more about the paging system but when i wire into that pair i only get hold music.

From the thread:

You have the diagram slightly wrong.

Person -->Phone-->3300MX Paging Port-->Customer provided Paging amplifier-->Amplifier drives the speaker(s).

The RJ45 port on the back of the system is does not generate enough wattage to drive a speaker. It is only designed to provide a milliwatt signal to an amplifier.  It is the amplifier that will drive the speakers.  I believe that just the middle pins (pair 1) are the active conductors.  There are many ways to phyically make it work. Everything from crimping an RJ45 plug on to a X-Connect pair that gets terminated on the Amplifier to a CAT5 Patch cord to a BIX JACK and using X-Connect from there.  Just use your imagination.

When you are in the programming of the system, Click Help and type Paging or loud speaker paging.  You should get lots of info on how/where to program the port on the back.  I would outline it for you but I don't have immediate access to the help files.

As a point of interest, you will not be able to page your sets at the same time as the you do loud speaker/overhead paging.  Not yet anyway.
