6408d+ work on TN 754B

[CERL]

I have 3 types of digital boards. TN754C, TN2224CP, and TN754B. I am running out of room on the TN2224CP boards and would like to know if the others are compatible with the 6408d+ digital phones. I thought I read somewhere they are but I can't find that back.

Thanks,

The 754's are for the older 7400 series sets that require 2 pairs of jumpers. The 8400 series sets will work 2 wire (1 Pair) or two pairs (like your tn754 packs). The 6400 series sets are a 2 wire only set. So you can use the tn2224, or the 16 port pack tn 2181.
