I am currently upgrading from a sx-2000 microlight to a 3300 mxe. i need to use the internal dsu and internal peripheral cabinet so they will become external to the 3300. does anybody know where i can find more information on using the triple fim card and the physical fibre connections for it. Does anybody know the programming steps for the dsu and percab(internal microlight cab). Do i program them on the 3300 ?
