Re: [802.3_ISAAC] comment 401 and 402



Hi Alireza, George,

 

A table is a good idea, but perhaps swap section and function columns and keep the sections in the same order in both tables.  Then update the functions column.  That way the information is given in the same order as it is found in the text and there will be fewer differences for the reader to digest between the two tables.  Just a suggestion.

 

In the resolution for #402 a few additional changes in the first paragraph (changes highlighted):

The PHY_D device includes the low-speed transmit function and high-speed receive function required for asymmetric operation over the link segment. The top-level arrangement of the high-speed PMA and PCS receive blocks, low-speed PMA and PCS transmit blocks, PHY control, link monitor, link synchronization, clock recovery, and OAM functions is shown in Figure 201-2.

 

Best Regards,

Scott

Alireza - looking at this editorially, it might be better to list where things are specified in a table.  In many other 802.3 clauses we've been fighting this issue of long sentences with lists of references and generally find that they are much more readable and useful in a table format.  I suggest the below, as a modification to what you have provided.

In your below, replace: PCS high-speed transmit function is specified in 201.3, PCS low-speed receive function in 201.4, and OAM behavior in 201.3.8. PMA high-speed transmit function is specified in 201.5, and PMA low-speed receive function in 201.6. PHY control is specified in 201.6.2, link monitor in 201.7.2, link synchronization in 201.7.3, and clock recovery in 201.7.4

 

with:

For the PHY_S, the functions are specified in the sections indicated in Table 201-xxx.

 

Table 201-xxx PHY_S functional specification references

 

Sublayer    Function                Section

PCS        high-speed transmit    201.3

PCS        low-speed receive    201.4

PCS        OAM behavior        201.3.8

PMA        high-speed transmit    201.5

PMA        low-speed receive    201.6

PMA    PHY control    201.6.2

PMA    Link Monitor    201.7.2

PMA    Link Synchronization    201.7.3

PMA    Clock recovery    201.7.4

 

Similarly for PHY_D:

In your below, replace: PCS low-speed transmit function is specified in 201.4, PCS high-speed receive function in 201.3, and OAM behavior in 201.3.8. PMA low-speed transmit function is specified in 201.6, and PMA high-speed receive function in 201.5. PHY control is specified in 201.6.2, link monitor in 201.7.2, link synchronization in 201.7.3, and clock recovery in 201.7.4.

 

With: For the PHY_D, the functions are specified in the sections indicated in Table 201-yyy.

Table 201-yyy PHY_D functional specification references

 

Sublayer    Function                Section

PCS        low-speed transmit    201.4

PCS        high-speed receive    201.3

PCS        OAM behavior        201.3.8

PMA        low-speed transmit    201.6

PMA        high-speed receive    201.5

PMA    PHY control    201.6.2

PMA    Link Monitor    201.7.2

PMA    Link Synchronization    201.7.3

I am following up on the discussion in today’s meeting regarding comments 401 and 402. I volunteered to rewrite the text related to these two comments.

 

For comment #401, we can use the following text:

 

The PHY_S device includes the high-speed transmit function and low-speed receive function required for asymmetric operation over the link segment. The top-level arrangement of the high-speed PMA and PCS transmit blocks, low-speed PMA and PCS receive blocks, PHY control, link monitor, link synchronization, clock recovery, and OAM functions is shown in Figure 201-1.

While the block diagram illustrates data, status, and control flow among these elements, detailed functional descriptions are provided in the remainder of Clause 201.  PCS high-speed transmit function is specified in 201.3, PCS low-speed receive function in 201.4, and OAM behavior in 201.3.8. PMA high-speed transmit function is specified in 201.5, and PMA low-speed receive function in 201.6. PHY control is specified in 201.6.2, link monitor in 201.7.2, link synchronization in 201.7.3, and clock recovery in 201.7.4

 

For comment #402, we can use the following text:

 The PHY_D device includes the low-speed transmit function and high-speed receive function required for asymmetric operation over the link segment. The top-level arrangement of the high-speed PMA and PCS transmit blocks, low-speed PMA and PCS receive blocks, PHY control, link monitor, link synchronization, clock recovery, and OAM functions is shown in Figure 201-1.

PHY control is specified in 201.6.2, link monitor in 201.7.2, link synchronization in 201.7.3, and clock recovery in 201.7.4.
