BT Openzone and new energy rules?


[link to this post]
 
How will this work?

Surely homehubs will still need to be active 24/7 to keep this service running?

Presumably even a router can drop into a low power standby-like mode if it's not being used 'in anger'. I don't think the article says that devices have to actually be powered off.

I suppose it's an energy variation of "look after the pennies and the pounds will take care of themselves", i.e. nibble away at all devices, even low consumption ones, and gradually total consumption will reduce, or not rise as fast.

The article is misleading when it says "switch off". I would anticipate a low power state which would do sufficient to keep things like DSL and WiFi connections alive whilst running in reduced processor power modes. ADSL2 also has low power modes which minimise power usage in standby modes (I don't think a VDSL has such a ratified mode at the moment as their are practical issues involved with higher frequencies and x-talk issues).

Here's one item on the subject of VDSL2 reduced power modes

Standby mode is the more appropriate phrase and savings will be small from routers as generally lot lower power than BBC article suggests

Surprising really.

My Openreach modem is rated 12v 1A which means over 12W once we allow for losses in the power plug, and my ASUS RT-N66U router is 19v 1.58A = 30W.

Though those must be peak rates, so resting will be much lower.

If they really do mean a "sleep" mode, along the lines of a modem only sync'ing on demand as we used to have on dialup, the two BT DLM's are going to need tweaking more than somewhat. Losing the PPP session frequently could also be a mess, even if only the router goes to sleep.

Low power modes to keep vdsl2 link exist and dual core devices could go into standby or underclock cpu .
