they used to say that if you wanted your computer to be safe you should turn it off. well, thats not true anymore. now you can turn things on over the inernet. I'm not sure how new this is to everyone. It was new to me since I've been gone from computers for a year or so. Today I ws going through the BIOS on my new laptop and I saw a setting that made me look twice. It was about allowing my comp to be turned on remotly through an ethernet connection. Now again, I'm not sure if this is new to you guys, but to me it was a little shocking. Luckly the default BIOS setup had it disabled. Right now 802.11af is being finalized and could be passed, if not already, very shortly. It would allow devices to get power from a cat5 cable so companies would not have to run AC cables to their APs. Now, we all know how secure wireless it, rite? I don't know, maybe it's just me (a paranoid caffeine addict), but the idea of somebody being able to turn on my laptop while I'm sleeping is a little freaky. There's a lot of info on this site if you want to read up on it a little more. http://poweroverethernet.com/

WOL(wake on lan) and WOR(wake on ring) have been around for a long time. I don't think those options have any thing to do with 802.3af or 802.11af(could be wrong). Now power over ethernet is something I've never heard of and it looks extremely interesting. I'm still reading over some of thier papers to try and learn more about how this would work, but from first glance it looks nice. I see it requires a unique 802.3af compatible power supply and im guess a compliant network card too. I wonder if they had any problems with magnetic fields from the transformers messing with hardrives or other opertions inside the machine. Another question is if it will be able to supply a power hog like a 21 inch CRT too.

Originally posted by Infinite: Erm, no. LMI is a protocol. Cisco is a sub-type of that protocol, as is ANSI and Q9333. Just like cisco has it's own versions of HDLC and frame relay encapsulation (HDLC is vendor specific for any given implementation of it, and the other frame relay encapsulation is IETF).
So no, Cisco is an equipment manufacturer and not a protocol.
Infinite Infinite , nothing but love for you man. Truely and honestly! However you are wrong. LMI is a term used to descript the portion of the frame the LMI will travle on. I have worked with Frame Relay, ATM, SMDS, FIDDI, and TLS for the past 3 years. Please do not make me post proof as I do not feel like typing that much crap no one else in here will care about. ANSI ANNEX -D is the most common Line protocol(LMI) used. Cisco(LMI Rev1) is the second most used. Cisco is LMI revision 1. I do have some documentation from our lucent switches if we are to debate this. Originally posted by Gizmo: Originally posted by Infinite: Erm, no. LMI is a protocol.

Infinite I love you! lol No Gizmo, you are still hating me..

POE or 802.11af has nothing to do with WOL. It is used to power devices such as VOIP phones and wireless access points. It is great for these devices because it is much cheaper than putting in electrical outletts but it does not have the power to run a computer in the current state of the technology. I could see how it could be used to suplement the battery or charge the battery of a laptop or something like that.
