If you have erased your configs, and have rebooted the router, then your configs are lost (including whatever configs you added under the t1 controller)
If you have erased your configs, and have NOT rebooted the router, then your configs are still there in the RAM (the NVRAM config is what has been erased). You could retrieve the configs on the NVRAM back, by using following command.
Router#copy run start
