[Campaign Classic] SMPP Connector

Hello communauty !

I have a little problem on my Adobe Campaign Classic instance ! We are in 6.1.0, and we would like to add a SMPP Connection to our external Mobile Provider. They gave me some information (URL, account, password..etc...) but I don't found the way to add an "Extended generic SMPP" external account, cause I don't find this option....

Only have the Generic SMPP option, but can't fill nothing with my providers's informations.

As you can seen, no Extended eneric SMPP option:

And no field to fill in Generic SMPP option:

Can someone help me to do this configuration ASAP ?

Thanks a lot !!
