I have a customer with a Definity that I'm looking to add phones to. They have TN754B 4 Wire/ 8-circuit pack cards.
I would like for someone to provide remote support for me to verify what ports are available and make the necessary programming changes.
Also would like to know if the 84XX series phones will work on these cards.

Thanks in advance.

I know this is old...but...

While I can't provide remote support for you, I can confirm that that 8400 series phones will work on this card. The 8400's can be either 2 wire or 4 wire. Just be aware that there is a "bug" on the earlier releases of the 8400 series that could cause the phone to not work on a 2 wire card after it's been used on a 4 wire card.
