It's a Motorola Type 2 SmartZone analog system:

A couple of things:
The radio will have a "flashcode", that will tell you what options the radio has and if it will support SmartZone trunking. If the flashcode doesn't support that, it's not going to work.
You didn't mention what band your XTS-3000 is. If it's not 800MHz, it's obviously not going to work.
There are also some tricks to making it work correctly and not interfering with their system. You should research Non-Affiliate Scan before you go much farther.
It's either going to take some trial and error on your part, or some outside assistance to make it work correctly. If you have not done it before, there can be some steep learning curves. Not impossible, but nothing like programming an HT1000.
Very important, no matter what any website tells you, Non. Affiliate. Scan. NAS. You do not want your radio to try and affiliate with their system. Legal issues will arise, and you can actually take resources on the trunked system away from the people that are supposed to be using the system.
If in any sort of doubt, get a scanner.
