What are the differences in model numbers?

[miller3383]

I am wanting to compare the differences between a Nortel 1140E NTYS05BC and a Nortel 1140E NTYS05BA. Is there a document somewhere that lists the difference in these revision numbers. Sometimes there is no difference from one revision to the next. Sometimes there are big differences. Can anyone help?

Most times just vintage, one will most likely have newer firmware then the other.
Either way you should up date the firmware.

Or....ICON keys rather than ENGLISH (NTYS05DFE6) for 1140e.
(Either way, Repair doesn't have the keys for the set you have.)

Check out the ICON keys for ACD M3905 sets. (555-4001-136 M3900 Reference Guide) The MAKE BUSY key looks like an Arrow crashing into a division sign. "There's an arrow on the log by the hole in the bottom of the sea." Others are exploding handsets (Emergency), sun rising over the phone(Answer Emergency) and other indecipherable cryptic symbols. One even looks like a mathematical expression of one person is less than two handsets. (Display Queue)
