The format here also shows the complete response line with the ReturnCode, TransactionId, and Commentary all included. The information is presented in this way in order to enable a better visualization of the commands and responses as actually transmitted by a call agent or gateway.

For decades, the common practice for commercial organizations that needed to establish data communication connections between locations or between organizations was the use of dedicated private communications links leased from telecommunications carriers. Prior to the Internet, private communications links were the only available method for setting up data communications. The establishment of the Internet made it theoretically possible for organizations to connect to one another simply by connecting to the Internet backbone and letting routers do the rest. Most organizations scoffed at this idea because of the Internet s reputation for unreliable performance, as well as its lack of security. Gradually, however, Internet performance has improved in many parts of the world, and security standards have been developed that make use of the Internet for an inter- and intra-organization communications medium a practical reality. This section describes threats, vulnerabilities, and countermeasures needed to protect Internet-based business communications.

Almost all of the disc recording applications with the exception of the simplest backup programs let you test the recording process prior to burning a disc. The essential feature was born out of the ease with which early CD-R systems destroyed media during the recording process. When

You have been using the return statement without much explanation since 2. As you know, the return statement performs two important operations: First, it will cause a function to return immediately to its caller. Second, it can be used to return a value. This section of the chapter presents some important issues related to both of these processes.

capabilities (P IE) compared to a single-ended amplifier configuration. Parallel amplifiers allow the entire parallel circuit to function as if it were a single high-power transistor, at any bias desired (Class A, AB, B, and C). Figure 3.105 demonstrates a complete parallel circuit, with impedance matching, biasing, and filtering. Parallel amplifier circuits must have excellently matched active devices, and their input and output capacitances will also be double that of a single device which can be problematic with high-frequency operation. Gain will stay the same whether a single power amplifier or a parallel power amplifier configuration is used. The advantage of paralleling amplifiers is that the output power capability (P1dB) will increase by 3 dB for two amplifiers (Fig. 3.106), and by 6 dB for four amplifiers. However, the input drive power into these paralleled stages must also increase to take advantage of this attribute. The input and output impedances of the combined amplifiers will decrease as more devices are paralleled. With 50-ohm MMICs, the ZIN and ZOUT of the total paralleled stages can be computed by 50/N, with N being the number of amplifiers in parallel. A matching network for the MMICs would therefore be necessary if we must match them into a 50-ohm system, or gain would suffer.
