I want to change 10 5400SM for 15 lites

I have 10pcs brand new 5400SMDD.
I dont need them because im going to use them on SCADA system which reqires only 9600kbps data transfer.
I would like to change them for 15pcs 5460SMBC lites.
For the price of buying licence you will get full 7Mbps SM.

SMBC?

Why not SMDD also?

If you are interested we can do exchange for 5460SMDD also.
