Talk:Physical layer

message: I'm missing embedded systems in this context. 
If I'm looking for ISO/OSI there is only information about TCP/IP and PC's and so on. 
What if I use a simple microcontroller and want to comunicate with other hardware on a PCB?
Yes, we need to mention I²S, I²C, Microwire, Serial Peripheral Interface Bus, System Management Bus, 1-Wire, X10 (industry standard) ... please add them to the article. At least the article does mention EIA-485, which is one of the more popular embedded system interfaces.

thread_title:  missing embedded system physical layers 

message: I tagged this article for lack of references because the only reference given does not touch upon most of the subject matter in the article and computers, networking, and telecommunications is an area of expertise where it is easy to have misconceptions which, if material is unreferenced, will work their way into WikiPedia. I have 25 years of experience in this field an still find that I suffer from the occasional misconception concerning the details of some subjects. I have discovered some of these misconceptions while looking for references to articles that I wrote on WikiPedia so I am sure that finding references is a Good Thing :-) --mlewis000 00:56, 20 December 2006 (UTC)

thread_title:  Lack of references. 

message: A section about the Physical Layer Signalling (PLS) sublayer was added. That is however only used in 10Base-T Ethernet, and may be moved to that article, or described in a wider context. Different IEEE protocols divide the physical layer into several sublayers. In e.g. 100 Mbps and 1000 Mbps Ethernet versions, the PLS sublayer is replaced by a Physical Coding Sublayer (PCS). See for example the IEEE 802.3a model (page 4 at http://grouper.ieee.org/groups/802/3/ae/public/mar00/booth_1_0300.pdf).
Perhaps someone would like to make a table, with one column for each protocol version, where all sublayers are presented. You may start out from the above pdf file. Mange01 (talk) 12:37, 14 April 2010 (UTC)
thread_title:  Sublayers 

message: says that media access control is handled by the physical layer. Data Link Layer says it is handled there. Data Link Layer has only one reference which does not cover this question. I'm inclined to believe the federal standard. --Kvng (talk) 13:45, 29 July 2011 (UTC)
replies: text: Don't.  IEEE invented the MAC sub-layer.  It's mapping to the data link layer is found in IEEE Standard 802-2001, where it is mapped beneath the LLC sublayer in the data link layer.  There is nothing physical about the MAC sub-layer: it has addresses for heaven's sake. — Dgtsyb (talk) 23:28, 29 July 2011 (UTC)

text: Actually, FS1037C does not say that media access control is handled by the physical layer: it says that it performs its function using the services of the physical layer (duh). — Dgtsyb (talk) 23:33, 29 July 2011 (UTC)
replies: text: Can you please add a ref or two to Data Link Layer? --Kvng (talk) 13:50, 31 July 2011 (UTC)
replies: text: Data Link Layer already refers to IEEE 802 as the source of the MAC sub-layer definitions.  Also, note that IEEE 802 is the ISO data link layer (ISO/IEC 8802), just add 8000 to the IEEE number to get the ISO/IEC number. — Dgtsyb (talk) 07:24, 2 August 2011 (UTC)

I've worked on updating case in a few of these articles.  Review and more would be appreciated.  Dicklyon (talk) 18:34, 26 October 2011 (UTC)
