30 seconds to replace DQ'd player

[A Pennsylvania Coach]

Maybe those of you that work NCAA can enlighten me. I understand that when a player fouls out, the coach has 30 seconds to replace them. That is, within 30 seconds, send a sub to the scorer's table. When the sub is at the table, play should resume. Correct?

More and more this looks like a 30-second timeout. Last night when the kid from Colorado fouled out, all the subs and assistants stood up, ringed the coach, started to talk, a sub went to the table and came back, the discussion continued, a horn blew, and the team broke the huddle. Is this permitted in NCAA? And if not by rule, is it understood that this behavior should be allowed?

I saw a HS playoff game two weeks ago. Here in PA we have the seat belt rule. So a player fouls out, and the coach stands up to address his four remaining players. The official tries to get him to sit but it becomes an argument. On one hand, the official is absolutely correct. On the other hand, that coach has probably seen this in hundreds of NCAA and NFHS games, and probably never seen a coach asked to sit back down.
