Reference Point R corresponds to the interface between TE2 and the TA. Reference Point S refers to the point of interface of an ISDN terminal and the NT2, serving to distinguish between terminal equipment and network-related functions. The S interface is de ned as a passive bus for up to eight NT2 devices. Reference Point T references a minimal point of termination at the customer premises. It is the reference point between the NT1 and NT2 devices. Reference Point U is the reference point between NT1 devices and line termination equipment in the carrier CO. The reference point describes the full duplex data signal on the physical two-wire subscriber line, including line coding and framing conventions. The U reference is relevant only in North America, as the NT1 function is provided by the carrier elsewhere. Reference Point V is the point of interface at the network side of the connection between the line termination or loop termination and the exchange termination. In other words, it is the point between the circuit-terminating equipment and the ISDN CO. As the V interface exists only if the CO does not have embedded circuit-terminating equipment, it is unusual in contemporary ISDNcompatible COs. Standard Interfaces and Channel Types

6. With either the DC in restore mode or with the services stopped, get to the command prompt and type ntdsutil and press Enter. First you need to set the active instance, so before going further type ac i ntds and press Enter. 7. After the utility opens, type files and press Enter. 8. Type info and press Enter. Current information about the path and size of the Active Directory database and its log les is displayed. Be sure to pay special attention to the path. You might want to write down this path information, shown in Figure 22-1.

Visual Studio has created a template event handling procedure for the Click event of the button control for you. All you have to do is fill in the code to handle the event. Add the following code to the Click event handler for the button: Dim TC As New localhost.CTemp() txtOutputTemp.Text = _ Format(TC.CTemp(CType(txtInputTemp.Text, Decimal), _ optFromUnits.SelectedItem.Value, _ optToUnits.SelectedItem.Value), "Fixed") As shown in the preceding example, the TC variable is declared to be an instance of the CTemp proxy class denoted by the localhost.CTemp namespace designator. Following this declaration is a single line of code that extracts the input arguments from the Web Form, calls the CTemp method on the proxy class (the synchronous form), formats the results, and inserts the value into the output text box. Let's take a closer look at the code that actually invokes the CTemp method on the proxy class.

Pause a print job. You can pause a print job that s in the queue by right-clicking it and then clicking Pause. If the job is already printing, Pause only stops the portion of the job that is still being spooled; if it s already in the printer s buffer, the printer will continue to print. When a job is paused, other jobs will move ahead of it in the queue automatically. Resume a print job. Right-click a paused print job and then click Resume. The remainder of the document in the spooler will be sent to the printer. If some of it has already been printed, you will need to collate the pages yourself. Restart a print job. If you have a paused printing and want to start the print job over from the beginning, right-click the print job and then click Restart. Cancel a print job. If a job has yet to print, this removes the print job from the queue altogether. Right-click the print job and then click Cancel. You can also select the print job and then press Delete. If the print job is already printing, any part of the job still in the spooler will be deleted while the remainder in the printer s buffer will continue to print.

Active Directory planning is a critical part of your Server 2008 deployment. The design of your Active Directory de nes the success or failure of your organization s Windows Server 2008 implementation. A great deal of planning goes into an Active Directory infrastructure, such as creating a forest plan and a domain plan for the forests, planning the organizational units, and developing the site topology. These topics are all covered in more detail in s 17 and 18, so if you study those chapters, you should have a good understanding of how to plan your Active Directory.

Refer to your network map and bring multiple copies to planning meetings for strategic placement of your company s domains. Test the link speed between all of your links and make sure you understand the actual link speed. Many times a T1 or fractional T1 may be further subdivided to support voice as well, which reduces the amount of data that
