Section 7.2 says:
+-----------+ +-----------+ | | | | | Calling | | Calling | | |----------->+ | |-----------+ +-----------+ 2xx | +-----------+ 2xx | 2xx to TU | 2xx to TU | | | | |
It should say:
BEFORE AFTER +-----------+ +-----------+ | | | | | Calling | | Calling | | |----------->+ | |-----------+ +-----------+ 2xx | +-----------+ 2xx | 2xx to TU | 2xx to TU | | | | |
Notes:
Figures 1 and 2 contain "BEFORE" and "AFTER" labels for their respective state machines. Figure 3 does not contain a "BEFORE" and "AFTER" label. Although it's pretty obvious from the context that the left-side is the "BEFORE" case and the right-side is the "AFTER" case, I believe for consistency (and to make it explicit), Figure 3 should contain "BEFORE" and "AFTER" labels.
