Scott – thank you. I prefer Option 3 – it’s well documented and clear.

Subject: [802.3_ISAAC] Possible resolution for comments #107 and #237 for d0.c
At the comment resolution meeting Tuesday it wasn’t clear what resolution would satisfy comments #107 and #237.
Some options to consider (not intended to exclude others) and can be discussed at the next comment resolution meeting:
Option 1: Implement the suggested remedy for #237 and withdraw/reject #107.
Option 2: Delete definition of tdd_watchdog_status on P216L17 and remove tdd_watchdog_status from Figure 202-28. This solution takes the approach that tdd_watchdog_status is a subset of conditions that would be detected earlier by (loc_rcvr_status = NOT_OK + hi_rfer)
Option 3:
- Delete definition of tdd_watchdog_status on P216L17
- At P216L53 insert definition of tdd_watchdog_timer: A timer used to determine that the TDD signal has not been detected within the last 10 TDD cycles. The timer shall expire 960 us +/- 50 us after being started.
- Make the changes to Figure 202-28 shown in the attachment
Best regards,
Scott
