We are looking at purchasing an executone model 228-OPXI and need to know compatability with what we are currently using. We have Meridian Phones, using a centrex system through the phone company. I am fairly unfamilar with the telephone system technology. Any assistance would be greatly appreciated

Thanks in advance

The OPXI is only for use on an Executone phone system the IDS.It requires a 48VDC power supply as well.

As PVJ stated Executone willl not work on Nortel system.
The OPXI converts a digital port to an analogue port, for use with fax, cordless phone, etc.

It depends on which Nortel system you have? Option or Norstar


If Norstar CICS, there is one built in. If ny other Norstr, you need an analogue adapter or analogue station module.

If option, you need a analouge station card.
