kudos:4 | Re: 100% Security During Boot 4 Peanuts ! Did it happen repeatedly? If just once it was probably coincidence. Thousands of users use that button and I have never before heard of anyone having the problem you describe. Perhaps you had a bad modem. I have had RR for four years and have used the button constantly on both the 4100 (two modems) and the 5100. I have never had a speed problem because of using the standby button.
Did you contact your ISP or Motorola about it? What firmware version were you using when this happened? Early firmware versions for the 4100 and 4200 had a major bug in them with regards to the standby button.

Birmingham, AL | Actually, the easiest method is a double pole single throw miniature switch mounted in a RJ45 outlet box connected between the DSL line and the jack terminals.
Switch ON. Switch OFF. Simple, easy, cheap and doesn't look to bad either. |

And Spanner's idea is a set and forget solution. Alittle more complex but worth it in the end. My adition of the program controling com port that trips the relay should a proccess be closed or crash is even more set and forget and would amp up your security by a large ammount.

This must come under the 'cool idea, but...' category, right?
If you're worried enough to do this, get a nat router (as low as $15 these days) and run behind that (as others suggested.) |

It -is- a really cool idea, and if Spanner designed the circuit himself, kudos to him for that, and he's got a little something neat to be proud of. For someone else who is an electronics hobbyist, it might be something interesting to play with, too. But most people would be better, more cheaply, and easier served by just getting a simple NAT router, IMO.

Birmingham, AL | I like the little circuit with the relay. That is a great idea. I might just build one with 2 remote switches so I can switch the DSL line from each workstation.
The older I get the lazier I get.:D Or is that just conserving my energy for other things..;) |

Your on a isp that allows servers lots of local wireless broad band providers allow this most are like wireless providers etc.
So sence your allowed and you got the band width to do so you set these servers up.
http server probably appache
sql server
your in to irc so you set up a ircd server and get it linked with your fave irc net work
you play CS and quake so you set up a dedicated quake 2 server maybe 2 (some like modded and un modded servers)
and to top it all off you need access to your servers remotly from work so you have vnc set up as well. Maybe theres 2 locations you need remote access from so you do http acess and vnc client access (ports 5800 and 5900)
Thats alot of ports some routers can be damn finicky when it comes to port fowarding maybe yours wont foward vnc ports for what ever reason so what you do is set up this server pc as dmz host and use a software firewall to protect the computer.
This set up is what makes spanners idea so attractive. Couple that with my additional idea of a relay controlled by a program that watches a few given procs and if one closes it trips the relay. This will kill the machins net access nearly instantly. If the fire wall retarts in case of failure the watcher app can trigger the relay switch to reconnect the pc.
Just because most of us do not have a set up similar to my example doesnt mean that soem lurker on the forum wont.
And o yeh lets not forget that the person might also need to do ocasonal dcc transfers on irc

Taking on board novaflares very useful suggestions about being able to trigger the circuit from an external source, i've designed an add on circuit for anyone wishing to achieve this too.
The original circuit remains as is, but with just a few extra componets.
A Positive, latched until clear, trigger voltage comes from your desired source, which obviously i have to leave to you, as i can't possibly know everyones configuration.
The Extra circuit when triggered switches the original Transistor and therefore trips the Relay out within 10 milliseconds. Also the circuit filters of any garbage on the feed above 16Hz.
As well as this i've included a protective voltage clamp to Transistor Q2 should an erroneous external voltage be inadvertantly applied. Both the original circuit and the new one are both protected from reverse voltages too.
The extra circuit draws no power from the original circuit, and Only around 50 mircoamps from the Trigger source so it will not present Any loading problems.

Parts list -
R3 = 100k
R4 = 100k
D3 = 1N914 or equivalent - Careful of orientation
ZD1 = Zener Diode 5.6Volt 500mW - Careful of orientation
C2 = 1 uf Non Polarised
Q2 = BC337 or equivalent - Careful of orientation

I was emailed with these questions, so i thought the following are also worth noting about the new add on design.
After the trigger voltage is released, the original circuit then slowly ramps back up via the normal preset time delay.
Therefore you are assured of double protection should the trigger ever be energised.
-
Also if you wish you can use a Polarised 1uf Electrolytic Capacitor for C2, with the + lead connected to the base terminal of Q2. Whichever you choose a voltage range between 10V - 100V is fine, but an Electrolytic Capacitor of closer to 10V will be cheaper and smaller.

Trigger Add On Circuit |
C2 1uf is replaced with a .1uf capacitor. This gives the stated 10 millisecond response time and 16Hz cutoff. Sorry for the previous shown value. The 1uf value would have been ok, but i thought it wise to change it to what it was when i first designed it. Just missed off a dot before the 1uf
