Why not a dialer interface must a 'chain of Dialer?

Hi guys, when linking an ISP using xDSL why does not need a "Dialer string"? The dialer interface is not supposed to make a call or dial or something like that? Thank you.

Hello

DSL technologies do any calls in all of your telephone network. They use just the cables from your home or office to the nearest telephone switch (the so-called local loop) for transmitting data on the frequencies significantly higher than that which would be allowed to go through the switchboard. These DSL signals is forks before the central telephone and diverted to a DSL access Multiplexer (DSLAM), while speech signals continue to be treated by the telephone. On the DSLAM, DSL signals are treated as data and then routed on the provider's data network.

So because DSL signals do not actually lead the telephone exchanges, no calls are made, and therefore, there is no necessary dialer string. DSL is a technology always - on - as soon as you plug your DSL modem or router to the telephone line, he started talking immediately on the line for the closest DSLAM.

Please feel welcome to ask for more!

Best regards

Peter

  • Why I can't receive calls, and why not activate my iMessage? I can't send or receive texts

    Why can't I receive calls? And why not my iMessage never activate? I can't send or receive texts

    You seem to have more than one thing is done. Calls and texts (SMS) are a function of carrier. If you are unable to receive calls, you must contact your operator. You can make calls? Regarding activation of iMessage, I believe that it is related to your problem of text. IMessage activate, the phone sends a SMS hidden on Apple servers to the United Kingdom. If your carrier doesn't support iMessage, either you don't have a SMS plan for your phone, then it will not send, and your phone will not receive the answer. Check with your carrier to solve the problems of your cell phones.

  • Error in Windows Media Player, Windows Media Player is not installed correctly and must be reinstalled. You want to install the Player from the Microsoft Website

    I don't know how or why it happened, but one day to another, WMP won't open. I tried to open an MP3 file, and he says that WMP has not been correctly configured "Windows Media Player is not installed correctly and must be reinstalled. Do you want to install the player from the Microsoft Website? ».

    I assumed that since I had to make some updates yesterday, that he was at fault, it had installed an update/new version of WMP and it was either buggy or doesn't work do not, so I went to the Windows updates, but no recent updates on the list had a remote connection with Windows Media Player.

    So, I accept the first proposal of the error message, and I'm headed to the Windows Media Player download page on the Microsoft Website. However, the version I should install (which was the one I already had) has Windows Media Player 12 for Windows 7. But this option is locked for me, and as I tried to install it, it says it is not compatible with my system. Not to mention, it's a whole package and not just the WMP installation.

    I tried everything and nothing seems to work. It won't even let me uninstall WMP because it won't let me open.

    My OS is Windows 7 Home Premium 64-bit. And the error messages that I get to try to launch any WMP feature (the tool, the installation program, no matter what), opens an error window stating that "there is a more recent version of Windows Media (12.0.7601.18150) player already installed on your computer. It is not possible to use and more old (12.0.7601.17514) installation package to install files or repair your current version of the reader. »

    Please, I ask for any intervention in this case.

    This arises from time to time, but I don't think that there is a difficulty of 100%.

    You can try (in no particular order)

    1. uninstall, reboot, reinstall WMP- http://www.howtogeek.com/howto/26107/how-to-reinstall-windows-media-player-in-windows-7-to-solve-problems/ if that doesn't help, try a SFC/scannow check - http://support.microsoft.com/kb/929833
    2. There is this diagnostic tool - http://support2.microsoft.com/mats/windows_media_player_diagnostic/ that can help (from http://support2.microsoft.com/fixit/en-us?wa=wsignin1.0 )
    3. You could try a system restore to a date before the problem occurred to see if that helps - http://windows.microsoft.com/en-us/windows/system-restore-faq#1TC=windows-7 and see if it gets a WMP work back
    4. Last resort, a repair install - http://www.sevenforums.com/tutorials/3413-repair-install.html
    5. Or just simply forget about WMP and try another party 3rd multimedia player that you can install and uninstall at will, as free VLC - http://www.videolan.org/vlc/

    But it may be worth waiting a while to see if someone else has a better solution.

    Why not first pro cc leaves me not to add an adjustment layer

    I guess just because you have not provided a lot of information, but most likely, you try to create the adjustment layer in the Menu file, without having to focus on the project Panel. If you select the project Panel, and then file > New > adjustment layer must be available. You can also create the adjustment through the new button layer in the project Panel.

  • Why not Camera Raw 6.7.1 w / Photoshop CS5 not converts from a Nikon D610 camera raw files?

    I just put my camera Nikon D90 for a D610.  I have been using Adobe Bridge to manage my pictures with the D90 and Camera Raw 6.3 to convert to use raw files in Photoshop CS5.  The new D610 wrote different raw files, so I've updated Camera Raw to the latest version (6.7.1) which is supposed to be compatible with the latest Nikon cameras.

    The D90 files always convert very well with Camera Raw 6.7.1 but cannot read the raw files of the D610.  Someone at - he saw no why not?

    Thank you

    You must have 8.3 beta version that works with CS6 and CC for D610.

  • Why not use the static methods - example

    Hello world

    I would like to continue the below thread about "why not use static methods.
    Why not use the static methods
    with the concrete example.

    In my small application, I need to be able to send keystrokes. (java.awt.Robot class is used for this)
    I created the following class for these "operations" with static methods:
    public class KeyboardInput {
    
         private static Robot r;
         static {
              try {
                   r = new Robot();
              } catch (AWTException e) {
                   throw new RuntimeException(e + "Robot couldn't be initialized.");
              }
         }
         
         public static void wait(int millis){
              r.delay(millis);
         }
         
         public static void copy() {
              r.keyPress(KeyEvent.VK_CONTROL);
              r.keyPress(KeyEvent.VK_C);
              r.keyRelease(KeyEvent.VK_C);
              r.keyRelease(KeyEvent.VK_CONTROL);
         }
    
         public static void altTab() {
              r.keyPress(KeyEvent.VK_ALT);
              r.keyPress(KeyEvent.VK_TAB);
              r.keyRelease(KeyEvent.VK_TAB);
              r.keyRelease(KeyEvent.VK_ALT);
         }
    
                   // more methods like  paste(), tab(), shiftTab(), rightArrow()
    }
    You think it's a good solution? How could it be improved? I saw something Singleton vs somewhere of static methods. Wouldn't be better to use Singleton?

    Thanks for your comments in advance.

    Maheshguruswamy thanks for the tips on the steps create a singleton of this class.
    Perhaps you could say also why do you say that it would be preferable to use singleton? What is behind it? Thank you!

    In short, it seems to me that a single instance of your class will be able to coordinate actions across your entire application. If a singleton should be sufficient.

    But who doesn't answer why he expected prefer a singleton instead of a bunch of static methods. Functionally, the two are almost identical. In both cases, there is that a single 'thing' to call methods - either a single instance of the class or the class itself.

    To answer the question, the main reason to use a Singleton on a class of static methods is the same reason readers much of not static vs static decisions: polymorphism.

    If you use a Singleton (and and interface), you can do something like this:

    KeyboardInput kbi = get_some_instance_of_some_class_that_implements_KeyboardInput_somehow_maybe_from_a_factory();
    

    And then everything calling public methods of KBI has to know that there an implementor of this interface, without worrying about what concrete class is, and you can replace some implementation is appropriate in a given context. If you do not need to do, then the approach of the static method is probably enough.

    There are other reasons that may suggest a Singleton - serialization, persistence, use as a JavaBean pop to mind - but they are less frequent and less convincing in my experience.

    And finally, if this thing keeps updated a State between method calls, even if you can manage it with static member variables, it is more in line with the OO paradigm to make them non-static fields of an instance of this class.

  • Why not set a number in this datagrid?

    Hello

    Flash CS5

    (Keep this separate from my other thread in order not to divert too much and help others with this problem.)

    I have a datagrid whose content is not pulled from an outside source, but written in the code just to test. The grid if you click above appears in a box of dynamic text on the stage, (after a section of youtube that used dynamic text) but I get:

    BusRoute: undefined

    Sttmnt1: Oxford

    Sttmnt2: Burford

    Sttmnt3: Swindon

    Why not the number?  It contains the number of this title for each line is said by the way.

    code is: -.

    Import fl.controls.DataGrid;
    import flash.events.Event;
    Import fl.controls.ScrollPolicy;

    var item1:Object = {BusRoute: '43', Sttmnt1: 'Oxford', Sttmnt2: 'Burford', Sttmnt3: 'Swindon'};
    var item2:Object = {BusRoute: "361", Sttmnt1: "Evesham", Sttmnt2: "ChippingNorton", Sttmnt3: "Am Buckingh"};

    var myTextFormat:TextFormat = new TextFormat();
    myTextFormat.font = "Arial";
    myTextFormat.color = 000000
    myTextFormat.size = 14;

    var datagrid:DataGrid = new DataGrid;
    DataGrid.Move (20.50);
    DataGrid.Width = 200;
    DataGrid.Height = 70;
    datagrid.rowHeight = 35;
    DataGrid.Columns is ["BusRoute", "Sttmnt1", "Sttmnt2", "Sttmnt3"];.
    DataGrid.Columns [0]. Width = 30;
    DataGrid.Columns [1]. Width = 70;
    DataGrid.Columns [2]. Width = 70;
    datagrid.resizableColumns = true;
    datagrid.horizontalScrollPolicy = ScrollPolicy.ON;
    datagrid.setRendererStyle ("textFormat", myTextFormat);
    datagrid.addItem (item1);
    datagrid.addItem (item2);

    addChild (datagrid);

    datagrid.addEventListener (Event.CHANGE, gridItemClick);

    function gridItemClick(event:Event):void {}

    DataGridSelectedRowText.text = "BusRoute:" + event.target.selectedItem.Task + "\n";
    DataGridSelectedRowText.appendText ("Sttmnt1:" + event.target.selectedItem.Sttmnt1 + "\n");
    DataGridSelectedRowText.appendText ("Sttmnt2:" + event.target.selectedItem.Sttmnt2 + "\n");
    DataGridSelectedRowText.appendText ("Sttmnt3:" + event.target.selectedItem.Sttmnt3 + "\n");

    }

    Envirographics


    In your objects item1 and item2 property you set first to be 'BusRoute.

    var item1:Object = {BusRoute: '43', Sttmnt1: 'Oxford', Sttmnt2: 'Burford', Sttmnt 3: "Swindon"};

    but in your attempt to acquire the data you seem to be referring to him as "stain".

    DataGridSelectedRowText.text = "BusRoute:" + event.target.selectedItem.Task + "\n";

    One of them must be changed to agree with each other.
