Calling TO?
 

What are the ways for a coach to signal with his hands, to the official, he wants a time out? In addition, a 30 second or 1 minute time out. Should this just be done verbally?

Thanks,

Coach can make a Coach's "T" directed to his players, or to an official. If he stands up the official can more easily recognize the request.

The coach may touch his shoulders for a 30 and/or make a verbal request.

If an official does not see or hear the 30 second request, the official may call a full time-out, although many officials will clarify the request before reporting the length to the scorer, partners and opponent.

Is the coaches "T" just like the "T" and official gives for a technical?

Thanks

Yes, just like that.

Yes it is but the officials is a little more devistating in its scope and power!
