Figure 16-10: The ADSL model as it is laid out from the customer premises to the service provider The next figure demonstrates the connection from the service provider to the rest of the world. In many cases, ADSL access to the local network access provider (the ILEC or other local loop provider) is then passed on to the ISP. This is designed to run over an ATM backbone, but not a firm requirement. Therefore, the NAP will assign a DSL Access Multiplexer card (DSLAM) and assign an ATM VPI and VCI as a default to carry the data into the Internet Service Provider ( ISP) or other Network Service Provider (NSP). This is shown in Figure 16-11 .

One reason why invoking overloaded constructors through this can be useful is that it can prevent the unnecessary duplication of code. In the foregoing example, there is no reason for all three constructors to duplicate the same initialization sequence, which the use of this avoids. Another advantage is that you can create constructors with implied default arguments that are used when these arguments are not explicitly specified. For example, you could create another XYCoord constructor as shown here:

CHAPTER 15:

We ve all witnessed the effect of perspective; for example, you make sure a train isn t coming, and then you stand on the tracks and look into the horizon. Apparently, the train tracks converge as they vanish at the horizon. Naturally, the tracks don t actually converge, or it would be difficult to drive a train on them. This is an optical illusion that demonstrates the very real optics of the human eye. Any object that has parallel sides (a milk carton, most tables) when viewed at an angle other than straight-on will look as though its parallel sides converge at a point somewhere in the distance. This point, whether you can see it on train tracks or imagine it by mentally extending the parallel lines, is called the vanishing point, and CorelDRAW s Perspective effect offers an onscreen marker for moving a shape s vanishing point. Depending on the angle upon which you view an object let s use a cube as an example you can see one, two, or three sides of the cube. When you draw a cube, face front, in CorelDRAW, you ve drawn a square; there is no perspective, and it s not a very visually interesting representation. If you can see two faces of the cube, you re viewing from a perspective point; the object is said to have one-point perspective. Naturally, you can t see more than three sides of a cube at one time, but when you do see all three front-facing sides, this is called two-point perspective. It s very visually interesting to pose an object (or draw one) using two-point perspective, and CorelDRAW can help you set up an object for twopoint as well as one-point perspective.
