In the local loop, the topological layout of the wires has traditionally been a single-wire pair or multiple pairs of wires strung to the customer s location. Just how many pairs of wires are needed for the connection of a single line set to a telecommunications system and network The answer (one pair) is obvious. However, other types of services, such as digital circuits and connections, require two pairs. The use of a single or dual pair of wires has been the norm. More recently, the local providers have been installing a fourpair (eight wires) connection to the customer location. The end user is now using separate voice lines, separate fax lines, and separate data communications hookups. Each of these requires a two-wire interface from the LEC. However, if a CATV provider has the technology installed, they can get a single coax to satisfy the voice, fax, data, and highspeed Internet access on a single interface, proving the convergence is rapidly occurring at the local loop. It is far less expensive to install a coax running all services (TV, voice, and data) than multiple pairs of wire, so the topology is a dedicated local connection of one or more pairs from the telephone provider to the customer location or a shared coax from the CATV supplier. This is called a star and/or shared star-bus configuration . The telephone company connection to the customer originates from a centralized point called a central office (CO). The provider at this point might be using a different topology. Either a star configuration to a hierarchy of other locations in the network layout or a ring can be used. The ring is becoming a far more prevalent method of connection for the local Telcos. Although we might also show the ring as a triangle, it is still a functional and logical ring. These star/ring or star/bus combinations constitute the bulk of the networking topologies today. Remember one fundamental fact: the telephone network was designed to carry analog electrical signals across a pair of wires to recreate a voice conversation at both ends. This network has been built to carry voice and does a reasonable job of doing so. Only recently have we been transmitting other forms of communication, such as facsimile, data, and video. The telephone switch (such as DMS-100 or #5ESS) makes routing decisions based on some parameter, such as the digits dialed by the customer. These decisions are made very quickly and a cross-connection is made in logic. This means that the switch sets up a logical connection to another set of wires. Throughout this network, more or fewer connections are installed, depending on the anticipated calling patterns of the user population. Sometimes there are many connections among many offices. At other times, it can be simple with single connections. The telephone companies have begun to see a shift in their traffic over the past few years. More data traffic is being generated across the networks than ever before. As a matter of fact, 1996 marked the first year that as much data was carried on the network as voice. Since that time, data has continued its escalated growth pattern, whereas voice has been stable.

want to protect their customers while the content industry wants to prevent the high-definition players from having (unprotected) high-definition analog video outputs. The DVI, HDMI, and DisplayPort connection standards, in conjunction with disc authoring restrictions, can prevent the transmission of digital content to unprotected displays. For those without a secure connection capability, their display may only be able to show a lower-resolution video stream (see The Analog Sunset section in 4). Another of the legacy connection issues that will be confronted by endusers has to do with digital audio signals. There are millions of A/V receivers on the market that have built-in decoders for Dolby Digital and/or DTS audio. Regrettably, none of these receivers directly support Dolby Digital Plus, DTS-HD, or Dolby TrueHD decoding, and very few provide a mechanism for delivering up to eight channels of uncompressed audio. In fact, most continue to sport S/PDIF or Toslink connectors, which are only able to carry up to two channels of uncompressed audio data. This is particularly problematic when a BD player is added to the setup because the BD disc formats include audio mixing capabilities that allow commentaries and sound effects to be mixed in with the feature audio content during playback. This may pose a problem, because in order to mix audio from different encoded sources, it must all be decoded in the player and mixed in the uncompressed audio domain. If any of the audio sources has more than two channels, the mixed result may exceed the capacity of a standard digital audio connection. Several solutions are being effectuated for this audio bandwidth problem, among them an audio encoder embedded in the player that would recompress the high-bandwidth audio data into, for example, a Dolby Digital 5.1 stream for delivery to the legacy decoder. Other solutions implement a bypass option, in which the user can choose to bypass audio mixing and send the primary Dolby Digital or DTS-encoded audio stream to his or her external A/V receiver. Still other options require new A/V receivers to support HDMI or other high bandwidth methods for delivering up to eight channels of uncompressed digital audio. BD players will provide a selection of output signals with a variety of connections j Analog stereo audio. This standard two-channel audio signal can include Dolby Surround encoding.

If a liquid sits in a tank, then it exerts force on the side of the tank. This force is caused by gravity, and the greater the depth of the liquid then the greater the force. Pascal s principle asserts that the force exerted by a body of water depends on depth alone, and is the same in all directions. Thus the force on a point in the side of the tank is de ned to be the depth of the liquid at that point times the density of the liquid. Naturally, if we want to design tanks which will not burst their seams, it is important to be able to calculate this force precisely.

you must understand how these affect query performance. If users filter their queries on objects that access nonindexed fields (because you did not define primary or foreign keys or because you added functions on all your dimension objects), their queries will be slow, and this is the fault of the universe designer. If your universe uses derived tables that generate complex subqueries, query performance here may also be affected. As a way of identifying performance bottlenecks, use the SQL that Web Intelligence or Desktop Intelligence generates to isolate if the data source is the culprit for poor performance or if the culprit is load and settings within the BusinessObjects Enterprise server. First, evaluate if the SQL could have been written in a more efficient way; if yes, then modify your universe accordingly. Next, run an explain plan to see how the database is processing the query. Full table scans are an indication that either the SQL is not generated efficiently or the database is not tuned. Lastly, assuming the query runs equally slow when submitted directly to the database, your database is the performance bottleneck, not the Enterprise server.

In order to develop a network design, we must establish certain design criteria. Among other things, we need to specify whether we will have a buildahead or some capacity buffer. For example, it is pointless to design a network that will only support the immediate demand. Taking such an

In a hierarchy, it is possible for both base classes and derived classes to have their own constructors. This raises an important question: What constructor is responsible for building an object of the derived class The one in the base class, the one in the derived class, or both The answer is this: The constructor for the base class constructs the base class portion of the object, and the constructor for the derived class constructs the derived class part. This makes sense, because the base class has no knowledge of or access to any element in a derived class. Thus, their construction must be separate. The preceding examples have relied upon the default constructors created automatically by C#, so this was not an issue. However, in practice, most classes will have constructors. Here, you will see how to handle this situation. When only the derived class defines a constructor, the process is straightforward: Simply construct the derived class object. The base class portion of the object is constructed automatically using its default constructor. For example, here is a reworked version of Triangle that defines a constructor. It also makes Style private since it is now set by the constructor.

When you define a class, you declare the data that it contains and the code that operates on it. While very simple classes might contain only code or only data, most real-world classes contain both. In general terms, data is contained in instance variables defined by the class, and code is contained in methods. It is important to state at the outset, however, that C# defines several specific flavors of members, which include instance variables, static variables, constants, methods, constructors, destructors, indexers, events, operators, and properties. For now, we will limit our discussion of the class to its essential elements: instance variables and methods. Later in this chapter, constructors and destructors are discussed. The other types of members are described in later chapters. A class is created by using the keyword class. The general form of a class definition that contains only instance variables and methods is shown here: class classname { // Declare instance variables. access type var1; access type var2; // ... access type varN; // Declare methods. access ret-type method1(parameters) { // body of method } access ret-type method2(parameters) { // body of method } // ... access ret-type methodN(parameters) { // body of method } } Notice that each variable and method is preceded with access. Here, access is an access specifier, such as public, which specifies how the member can be accessed. As mentioned in 1, class members can be private to a class or more accessible. The access specifier determines what type of access is allowed. The access specifier is optional and, if absent, the member is private to the class. Members with private access can be used only by other members of their class. For the examples in this chapter, all members (except for the Main( ) method) will be specified as public. This means they can be used by all other code even code defined outside the class. (The Main( ) method will continue to use the default access because this is the currently recommended approach.) We will return to the topic of access specifiers in a later chapter, after you have learned the fundamentals of the class.
