Auto shut down of modem for mtnl broadband

[sumit4u13]

i got RT300R2U modem,does script for this modem automatically shut downs at 8 O clock(even if power supply is avilable to modem), or does it just reboot the modem.i want a script which shuts down the modem i.e all its led should be off at 8 O clock even the power supply to modem is avilble through mains to modem.:huh::huh::huh:

it reboots modem..what u want is not possible

it reboots modem..what u want is not possible
but it will start a new session at 8 o clock onwards and even if computer is shut down it will get charged for a new session

1. Presume you want the system also to be switched off at 8AM.2.Usually Mains power is connected to system . 3.From another point the Monitor is connected. 4.Remove the monitor Power supply cable and 5.connect it direct to mains/stabiliser. .6.Connect the Modem adaptor input to same plug 7.Any auto scheduler will switch off both the computer and modem at 8AM.

It can be done :urock:

i have a bad idea !!



Hardware solution
-----------------
SMPS powers the internal devices such as HDD, DVD Drive, FDD, Sys Fan etc.

likewise supply power to modem from SMPS itself.
Modem takes 10V 550mA input. Yellow and Black wire from SMPS gives 12V output. with a simple connector pin and with 2 meters of wire, you can easily connect SMPS's output to Modem's power input pin.
[Note: Modem's adapter is UNused]


Problem with this techniq?
-------------------------
oops !
Instead of 10 Volts we supply 12 Volts to modem.
=> 2V extra wont harm and its works perfect.
if you think 2V extra MAY harm, then you can use 7810mosfet transistor in series with SMPS's 12v power line to modem. 7810 cuts off the voltage above 10V.

oops !
Overload to SMPS.
=> its like connecting extra fan to chasis - no overload to SMPS


Advantage of this hardware solution
-----------------------------------
> Modem turns ON only when computer[SMPS] is ON
> Modem goes OFF if you shutdown/hibernate your computer
> Simple connection and costs just 10 to 20 Rupees for both connector and wire
> Saves power by turning OFF the modem when computer's SMPS is OFF


Disadvantage of this hardware solution
-------------------------------------
> StandBy wont turn OFF modem !!
> Suitable only for personel desktop computer.
> Its NOT suitable when you have multiple computers connected to single modem with/without wire.


Caution!
--------
Do not short-circuit the SMPS output, use insulatons where ever possible.

i have tried this techniq with modem UT300R2U, and it works fine
