What Are The Differences in the Ring Check Function Between Earlier-Version and Later-Version MA5600T?

• The processing mechanism of the ring check function of an earlier-version MA5600T has the following disadvantages:
  • After a loop is detected, Huawei MA5600T deactivates the ONT. In this way, live-network configurations are modified.
  • After Huawei ONT like HG8546M is deactivated, you need to manually activate the ONT (that is, re-configure services). This increases the workload.
• The processing mechanism of the ring check function of MA5600T V800R009 (or later versions) is optimized in terms of the following aspects:
  • After a loop is detected, the MA5600T makes the ONT go offline. In this way, live-network configurations are not modified but the ONT is stopped from transmitting services.
  • The MA5600T automatically makes the offline ONT go online after a period of time elapses. Note that the length of this period of time is configurable.
  • An easy-to-use query function is provided. With this function, you can query all ONTs that go offline because of loops.
• If you need to query all ONT deactivation records, run the display event history eventid command to query the information about events 0x2910000d and 0x29100026.

Event 0x2910000d indicates the PON port status; event 0x29100026 indicates the non-PON port status.
