The important thing to note about T3 events, is that the circuit will reset (a T4 event) if there are 16 successive T3 events with 200ms between them.

You could have loads of T3 events that are outside that timing envelop. The referenced article states

... not all T3s will cause a reset if communication is restored within 10 T3 periods or 20 seconds. When T3 timeouts occur, but not enough occur in succession to trigger a reset, slow speeds are often a symptom as these timeouts slow down the TCP/IP handshakes necessary to maintain internet connections.

So, the thing for the user to note is whether or not slow speds are happening.
