Definition of NE[edit]

The Synchronization architectures section starts using the abbreviation NE, but I could find it defined anywhere. (I did a find-on-page for "(NE)" with no matches.) — Preceding unsigned comment added by Jdimpson (talk • contribs) 19:46, 25 July 2013 (UTC)[reply]

Looks like that comes from [1]. Not defined there either. It looks like we may also have a copyright issue with some of the text and diagrams. ~KvnG 13:56, 30 March 2014 (UTC)[reply]

Kvng is right - those images appear to have been copied - not to mention I question the accuracy of the one which mentions SONET and SDH. NE is a standard abbreviation in the telecom world: Network Element. It refers to most any equipment in the network which manipulates the data (so switches, routers, SONET/SDH nodes, etc). I don't believe it would refer to things like DWDM systems (or any other optical switches or mux's).—Mrand ^{Talk • C} 21:00, 24 February 2015 (UTC)[reply]

It looks like someone fixed the NE issue, but now the Architecture section begins with a non-sentence. I'm not sure what was intended there, so I'll leave it with some of you. Jasonnet (talk) 14:59, 25 January 2021 (UTC)[reply]

Confusion[edit]

I disagree with the statement that Synchronous Ethernet devices must also support Power over Ethernet. This is not correct. Perhaps there was some confusion with the requirement to support the Ethernet Synchronous Messaging Channel (ESMC) defined in ITU-T recommendation G.8264 and which is based on the use of IEEE 802.3 Organizational Specific Slow Protocol (OSSP)

To me it looks like that refered to the IEEE 1394 proposal, which used the same name from consumer electronics manufacturers, not the ITU-T recommendation which seems a different group (phone companies). Will try to clarify with citations. W Nowicki (talk) 23:53, 9 July 2011 (UTC)[reply]

For what the thing is?[edit]

It is absolutely unclear a rationale behind the topic. I understand *how* it works, but couldn't got answer for "*Why?*" and "*For what?*" questions. Avesus (talk) 18:15, 27 March 2014 (UTC)[reply]

I've added a link in the lead to Time and frequency transfer. Does that help? ~KvnG 13:56, 30 March 2014 (UTC)[reply]
