RE: [EFM-P2MP] Missing section on FEC Error monitoring capability
Hi Ben,
The text I grabbed for this section include 3 counters. I'll write a comment
to include the following text:
65.2.4.4 Error monitoring Counters
The following counter applies to FEC sublayer management and error
monitoring. If an MDIO interface is provided (see CROSS REF Clause 22), it
is accessed via that interface. If not, it is recommended that an equivalent
access be provided.
These counters are reset to zero upon read or upon reset of the FEC
sublayer. When a counter reaches all ones, it stops counting.
The counters purpose is to help monitor the quality of the link.
65.2.4.4.1 buffer_head_coding_violation_counter:
16-bit counter. When the receiver is in normal mode,
buffer_head_coding_violation_counter counts once for each invalid code-group
received directly from the link.
65.2.4.4.2 FEC_corrected_Blocks_counter
16-bit counter. When the receiver is in normal mode,
FEC_corrected_Blocks_counter counts once for each corrected FEC blocks in
the decoding.
65.2.4.4.2 FEC_uncorrected_Blocks_counter
16-bit counter. When the receiver is in normal mode,
FEC_uncorrected_Blocks_counter counts once for each uncorrected FEC blocks
in the decoding.
I'll also try to sort the text for 30.
Best Regards,
Lior

Lior,
Would you care to put together some text for this section? A list of
counters
might be a good place to start, though complete text would be much more
helpful and would reduce the amount of editiing at the next meeting. These
counters will need to be coordinated with Clause 30 at least and perhaps
Clause 45.
Are there any other ideas out there?
Thanks,
Ben
