Vertexstandard VXR9000 configuration

I am new to repeater configuration for multichannel for different departments. Please help me.

I want to configure VXR9000 for multichannel for different departments so that each department can communicate securely. I want to use one duplexer with one antenna and i want 32 channels with same tx rx freq but differnet dcs/ctcss for dividing channels. So is it possible to that way to solve my requirement with single repeater. Is there any other ways to have 32 channels or anything to configure in repeater software.

Thnk you in advance
Best Regards
