mance, and can actually damage RF stages. Designing a switch that switches to a 50-ohm termination in the off position will allow a desirable high return loss, minimizing reflections. RF relays are less dependable than PIN switches and slower, larger, and more costly. Relays are, however, better for high-powered, wide bandwidth, low-IMD applications. For basic switch requirements, a single or double diode configuration will serve most needs except for switching reactive loads. The inductance of the load (such as an RF filter), has an undesired proclivity to resonate with the diode s off capacitance, which can give the switch very little of the off isolation that was expected. 8.3 Automatic Gain Control

SS7 signaling links are characterized according to their use in the signal-ing network. Virtually all links are identical in that they are 56 Kbps or 64 Kbps bidirectional data links that support the same lower layers of the protocol; what is different is their use within a signaling network. The bidirectional nature of these links enables traffic to pass in both directions between signaling points. Three basic forms of signaling links exist, although they are physically the same. They all use the 56 Kbps DS0A in North America and 64 Kbps DS0C data facilities in nearly every other portion of the world (except Japan where they still use a 4.8-Kbps link). The three forms of signaling links are as follows:

It is also used to configure the system to speak descriptive names for those features over the telephone. This configuration page is shown in Figure 7-8.

Here is an example of the use of the Windows arp command:

Part I:

The default lifetimes are 3600 seconds (one hour) and 4,608,000KB of traffic sent across the SA. Changing the timeout values with the preceding commands affects only newly built SAs; existing SAs will use the timeout values that previously existed when the SAs were built.

Examples: If([Country]="US";[Resort];"") returns the value in [Resort] when [Country]= "US" and "" when [Country]<> "US". If([Year]=2006; [Revenue]; 0) returns the value in [Revenue] if the [Year]=2006.

As you know, C++ does not support a built-in string type, per se. It does, however, provide for two ways of handling strings. First, you may use the traditional, nullterminated character array, with which you are already familiar. This is sometimes referred to as a C string. The second way is as a class object of type string, and this approach is examined here. Actually, the string class is a specialization of a more general template class called basic_string. In fact, there are two specializations of basic_string: string, which supports 8-bit character strings, and wstring, which supports wide-character strings. Since 8-bit characters are, by far, the most commonly used in normal programming, it is the version of basic_string that is examined here. Before looking at the string class, it is important to understand why it is part of the C++ library. Standard classes have not been casually added to C++. In fact, a significant amount of thought and debate has accompanied each new addition. Given that C++ already contains some support for strings as null-terminated character arrays, it may at first seem that the inclusion of the string class is an exception to this rule. However, this is actually far from the truth. Here is why: Null-terminated strings cannot be manipulated by any of the standard C++ operators. Nor can they take part in normal C++ expressions. For example, consider this fragment:
