Example text

TDM allows voice networks to carry multiple conversations at the same time over a single, four-wire path. Because the multiple conversations have been digitized, the numeric values are transmitted in specific time slots (thus, the 舠time division舡) that differentiate the separate conversations. Figure 1-7 illustrates three separate voice conversations sent over a digital connection. Figure 1-7. Time-Division Multiplexing Voice Channels Notice each of the voice conversations in Figure 1-7 has been digitized and assigned a numeric value and transmitted over the digital PSTN connection.

This allows users to get all messages in one place and easily reply, forward, or archive messages. 舦 Increased productivity: VoIP extensions can forward to ring multiple devices before forwarding to voicemail. This eliminates the 舠phone tag舡 game. 舦 Feature-rich communications: Because voice, data, and video networks have combined, users can initiate phone calls that communicate with or invoke other applications from the voice or data network to add additional benefits to a VoIP call. For example, calls flowing into a call center can automatically pull up customer records based on caller ID information or trigger a video stream for one or more of the callers.

Even if you have a solid grasp of the information, many other factors play into the testing environment (stress, time constraints, and so on). If you pass the exam on the first attempt, fantastic! If not, know that this commonly happens. The next time you attempt the exam, you will have a major advantage: You already experienced the exam first-hand. Although future exams may have different questions, the topics and general 舠feel舡 of the exam remain the same. Take some time to study areas from the book where you felt weak on the exam.
