The term cognitive refers to the act of knowing or recognizing our experiences. So cognitive therapy is an organized, systematic psychological treatment that teaches people how to change the thoughts, beliefs, and attitudes that play an important role in negative emotional states like anxiety or depression.

The basic idea in cognitive therapy is that the way we think influences the way we feel, and therefore changing how we think can change how we feel.

The best way to work through this book is mostly in order, reading the first eight chapters and then turning to the specialized cognitive therapy chapters that provide specific interventions for panic attacks, social anxiety, and worry (Chapters 9–11) if you need more help.

In Chapter 3 you’ll read about the anxious mind—the cognitive view of anxiety. Then, in Chapter 4, you will learn about how cognitive therapy works and what types of exercises you’ll be doing to address your anxiety using this book. In Chapter 5 you’ll create your own anxiety profile, which will be packed with information that you’ll use throughout the book’s exercises so that you really target your unique problems and identify your strengths. You should complete the exercises and worksheets as you read through Chapters 1–5 of the workbook.

In Chapters 6 and 7 you’ll learn the techniques that will help you lessen anxietyand its hold on you. We suggest you read those two chapters without doing the exercises and then follow the instructions in Chapter 8 for putting together the cognitive and behavioral techniques into an Anxiety Work Plan that you can use to systematically carry out your cognitive therapy program. Then start implementing the work plan by doing the exercises and worksheets you’ve selected from Chapters 6 and 7.

An example of a goal for behavioral change might be to speak up and give your opinion more often at office meetings, a cognitive goal might be to stop assuming that every time your chest feels tight it could be a heart attack, and an emotional goal might be to feel less tense and agitated whenever you think about retirement.

BACnet internetworks that are connected only by routers that understand BACnet frames are defined here as directly connected internetworks.

#bacnet

If an IP router has a connection to a BACnet network and receives a BACnet frame that needs to be delivered to another network, it will do...nothing.3

The problem is solved with special kinds of BACnet devices that also understand the IP protocol. Such a device is able to take a BACnet message and enclose it within an IP frame that an IP router can read and deliver across an IP internetwork.

At the destination, another such BACnet device extracts the BACnet message from the IP frame, reads it, and forwards it if necessary.

Annex H.3 of the original BACnet standard describes this technique known as "tunneling," by which devices called B/IP PADs (BACnet/Internet-Protocol Packet-Assemblers-Disassemblers), also known as Annex H.3 devices, act like routers to transport BACnet messages across IP internetworks.

A recent addition to the BACnet standard, Annex J-BACnet/IP, describes a flexible extension of the original concept. It even includes descriptions of BACnet/IP devices that always enclose their BACnet messages within IP frames.

Depending upon the implementation, a set of intercommunicating PADs can look to devices on the BACnet networks like a single physical router with a port on each of the BACnet networks to which it is connected.

The IP routers and networks that participate in the communications are completely invisible to the BACnet devices.
