A 16 circuit ONS line card for my Mitel sx-50 recently failed, and I have noticed that I have only lost 4 phone lines. The 66-block the card is connected to is marked out for more lines, but they were never used. Can I replace the 16 circuit card with an 8 circuit without having to worry about programming or re-wiring? All of the lines which are in use are at the top of the block, so I assume they are connected to the first few pins which connect to the card (if this makes a difference?).

Of course this means I am in the market for such a card. So let me know if you have one for sale.

Try our sponsor for the card, click on 'EQUIPMENT'. If that fails there are several equipment sellers that post here in Mitel.

And yes, you can sub an 8-circuit for a 16 circuit, as long as you aren't using circuits 9-16. 1-8 use the first 16 rows with color codes white/blue through green/red.
