Let's first clarify on whether the device that you call an ATT "modem" is really a simple modem. Chances are, it's not.
A modem will have only one Ethernet port. If your "modem" has more than one Ethernet port, it is a modem/router, also called a gateway. This is a device that combines both a modem and a router in one physical package.
So, if your ATT "modem" is really a modem/router or gateway, then you can connect your MacBook Pro directly to the device using an Ethernet cable connection. Be sure to turn off the WiFi on the Mac, to make sure that the connection will be over Ethernet rather than WiFi.
If you are planning to use the Time Capsule for Time Machine backups from your Mac, the Time Capsule will also need to connect to the modem/router or gateway using an Ethernet cable connection.
