Read an Excerpt

Chapter One: Determining Remote Access Needs

After completing this chapter, you will be able to:
  • Describe various wide area network (WAN) services
  • List different kinds of circuit-switching connections
  • List different kinds of packet-switching connections
  • Describe various WAN encapsulation types
  • List the signaling standards used with serial connections
  • Explain the difference between synchronous and asynchronous serial communications
  • Describe site considerations to use in selecting remote access services and equipment
This chapter examines remote access services and the reasons to use such services. Wide area network (WAN) communication occurs between geographically separated areas. In enterprise internetworks, WANs connect the central office to remote branch offices. When one branch office wants to communicate with another remote branch office, information must be sent over one or more WAN links. You need to examine the needs of the branch and central offices, so that you can determine what kind of WAN services and WAN encapsulation protocols should be selected, and what routers and router interfaces need to be purchased. Routers within enterprise internetworks represent the local area network (LAN)/WAN junction points of an internetwork. This chapter will define these junction points by describing the WAN services they use.

WAN Services

WAN communication is often called a service because the network provider often charges users for the services provided by the WAN. These charges are known as tariffs. WAN services are provided primarily through the following three technologies:
  • Dedicated lines (sometimes referred to as leased lines)
  • Circuit switching
  • Packet switching

Dedicated Lines (Leased Lines)

Dedicated lines are fixed connections, which do not involve establishing a new connection each time the link is used. They are permanent end-to-end connections. The telecommunications company provides a dedicated high-speed connection between the two desired locations, at speeds ranging from as low as 9600bps to as high as 45Mbps. The higher the speed, the greater the monthly fixed cost of the line. The connection is available 24 hours a day, 7 days a week, and is thus suited to companies that want permanent connections between their office branches, or perhaps to a company that wants a permanent connection to the Internet. One big advantage of dedicated lines is that you, the customer, own all the bandwidth on the connection, giving you a lot of flexibility for your WAN needs.

The basic unit of measurement for dedicated lines is a T1 connection, which supports 1.544Mbps. A T3 connection supports 45Mbps. Fractional T1 circuits are available in units of 64Kbps, with connections of 384Kbps, 512Kbps, and 768Kbps being common. The connection is implemented with two units:

  • Channel Service Unit (CSU)—This unit provides the interface to the dedicated line.
  • Data Service Unit (DSU)—This unit interfaces between the CSU and the customer's equipment, using RS-232 for low speeds up to 56Kbps, and V.35 (RS-422/499) for higher speeds. It is common to have the units as a single component. Several modular Cisco routers can include CSU/DSUs as add-on modules.
Dedicated lines use synchronous communication links. Synchronous communication is usually much more efficient in use of bandwidth than asynchronous. With synchronous communications, the two devices initially synchronize themselves to each other, and then continually send characters to stay in sync. Even when data is not really being sent, a constant flow of bits allows each device to know where the other is at any given time. That is, each character that is sent is either actual data or an idle character. Synchronous communications allows faster data transfer rates than asynchronous methods because additional bits to mark the beginning and end of each data byte are not required. A 56Kbps synchronous line can be expected to carry close to 7000 bytes per second (that is, 56000/8), whereas the async data rate would be 56000/10. Another advantage of synchronous communications is that the frame structure allows for easy handling of control information. There is a natural position (usually at the start of the frame) for any special codes that are needed by the communication protocol.

Synchronous connections must always be in sync even if they have to make adjust-ments. The accurate decoding of the data at the remote end is dependent on the sender and receiver maintaining synchronization during decoding. The receiver must sample the signal in phase with the sender. If the sender and receiver were both supplied by exactly the same clock source, transmission could take place forever with the assurance that signal sampling at the receiver was always in perfect syn-chronization with the transmitter. This is seldom the case, so in practice the receiver is periodically brought into sync with the transmitter. It is left to the internal clocking accuracy of the transmitter and receiver to maintain sampling integrity between synchronization pulses.

Signaling Standards
A number of different standards define signaling over a serial cable, including EIA/ TIA-232, X.21, V.35, EIA/TIA-449, EIA-530, and V.25bis. Each standard defines the signals on the cable and specifies the connector at the end of the cable.

Circuit Switching

Circuit switching is a WAN switching method in which a dedicated physical circuit is established, maintained, and terminated through a carrier network for each communication session. Circuit switching accommodates two types of transmissions: datagram transmissions and data-stream transmissions. Used extensively in telephone company networks, circuit switching operates much like a normal telephone call. Circuit switching moves data between two points by setting up a physical link, or circuit, between them. Data flows in a stream along a circuit that lasts as long as necessary, at which time the switches and lines used to build the circuit are freed for another connection.

The usual example of a circuit-switched network is the plain old telephone system (POTS) network. When you dial a phone number, the phone company's switching equipment sets up a direct circuit between your telephone and the destination. The chief advantage of circuit switching is that the flow of data (for example, your voice) is not subject to delays introduced by the network, and the recipient receives data exactly as it was sent. The big disadvantage is that much of the connection's available bandwidth may be wasted due to the bursty nature of data traffic, which will rarely saturate the link's capacity. Figure 1.1 illustrates how a laptop can dial into an access server using POTS.

There are two commonly used circuit-switching methods:

  • Asynchronous serial—Dial-up using modems
  • Integrated Services Digital Network (ISDN)—Two types: Basic Rate Interface (BRI) and Primary Rate Interface (PRI)

Asychronous Serial Communication

Asynchronous serial communication uses the existing telephone network with its associated low cost. Asynchronous communication happens when using the exist-ing dial-up telephone network and when a connection is made between the two modems by dialing the number assigned to the other modem. Generally, connections are established for limited durations. This suits remote access users who might want to dial into their network after hours, or small offices that dial into their Internet Service Provider at regular intervals during the day to exchange email.

To allow an asynchronous serial call, a Cisco router needs to have an asynchronous serial interface attached to a modem. If the router uses an external modem, the inter-face on the modem will need the EIA/TIA-232 signal standard, and the interface to the telephone company will need the standard RJ-11 adapter....

Figure 1.1 Circuit-switched network.


Types of Serial Communications

There are two basic types of serial communications, synchronous and asynchronous. Asynchronous means "no synchronization," and thus does not require sending and receiving idle characters. However, the beginning and end of each byte of data must be identified by start and stop bits. The start bit indicates when the data byte is about to begin, and the stop bit signals when it ends. The requirement to send these additional two bits causes asynchronous communications to be slightly slower than synchronous; however, it has the advantage that the processor does not have to deal with the additional idle characters. The serial ports on IBM-style PCs are asynchronous devices and therefore support only asynchronous serial communications.

An asynchronous line that is idle is identified with a value of 1 (also called a mark state). By using this value to indicate that no data is currently being sent, the devices are able to distinguish between an idle state and a disconnected line. When a character is about to be transmitted, a start bit is sent. A start bit has a value of 0 (also called a space state). Thus, when the line switches from a value of 1 to a value of 0, the receiver is alerted that a data character is about to come down the line.


ISDN

ISDN connections, like asynchronous serial connections, are circuit-switching connections. They are intended to compete with POTS by providing voice, data, and other traffic across a telephone network. Logically, ISDN consists of two types of communications channels: bearer service B channels, which carry data and services at 64Kbps; and a single D channel, which carries signaling and control information that is used to set up and tear down calls. The transmission speed of the D channel depends on the type of ISDN service you've subscribed to. ISDN services can be divided into two categories: Basic Rate Interface (BRI) service and Primary Rate Interface (PRI). Both services will be described in the following sections. ISDN configuration will be discussed in greater detail later in Chapter 6.

Basic Rate Interface (BRI)

ISDN BRI is the most basic ISDN interface. ISDN BRI provides the customer with two 64Kbps B channels and one 16Kbps D channel, all of which may be shared by numerous ISDN devices. It is the ideal service for homes and small offices, which, in the interest of controlling expenses, require a service that can integrate multiple communications needs. By bundling the two B channels together and using 2:1 data compression, an ISDN BRI link can achieve data throughput of over 250Kbps. You can have up to eight ISDN devices connected on a single bus because signals on the D channel automatically take care of contention issues as they route calls and services to the appropriate ISDN device. This allows you to have a router, phone, fax machine, and video conferencing equipment all sharing the same ISDN line. Although only two B channels are available to be used at any point in time, numer-ous other calls may be put "on hold" via D-channel signaling (a feature referred to as multiple call appearances). The D channel uses Link Access Procedure (LAPD), which is a data link protocol....

    Skip this one. The Cisco guide is better.

    Having gone through various certification (CNE,MSCE,CCNA, and 2 CCNP exams) I have never had to refer to more than one book to prepare for a exam. This book does not explain concepts clearly and is full of errors. The real world projects at the end of each chapter really suck. Now using the Cisco book instead. I found the Exam Prep book for the Switching Exam to be well written but this one is really disappointing.

    I am one of the authors...

    This book will prepare you for Cisco's CCNP Remote Access Exam (640-505) This book contains all of the information that you will need in order to pass Cisco's Remote Access exam (640-505), a stepping stone for your CCNP certification. As a certified Cisco instructor for five years, I have helped many students in their struggle for certification. Besides teaching the BCRAN class, I teach the ICND, BCMSN, BSCN, CATM, DCN, CID, BSSC, and MSSC classes. I also bring a real-life perspective to not only my teaching, but to this book. I have been in this industry over a decade, have my own consulting company based in Orlando, FL, and have written two books on Cisco's Catalyst switches entitled 'CCNP: Switching Exam Cram' and 'CCNP: Cisco LAN Switch Configuration Exam Cram'. I also have a variety of CDROM testing products with the Coriolis book, all geared to helping you pass various CCNA and CCNP Cisco certification tests. This book will explain the fundamental ABC's of Remote Access with Cisco's products and the tools available to you to design, implement, and configure remote access solutions in very large WAN environments. All of the objectives outlined by Cisco's BCRAN class as well as other important remote access topics are covered thoroughly in this book. These topics include: a thorough discussion of Cisco products for remote access; serial communications and cables, including console and modem access; modem configuration and dialing on both Cisco routers and Microsoft Windows machines; the PPP protocol and its implementation; ISDN implementation and configuration; dial-on-demand (DDR) routing and dialer profiles for router dial-up solutions; X.25 and frame relay WAN solutions; backup solutions using dial-up; managing bandwidth using queuing and compression; address translation with NAT and PAT; security and AAA configuration; and many, many more. Besides an overview of these subjects, I explain the necessary configuration commands to implement these features in your WAN network. You will be presented with detailed configuration examples as well as many example test questions following each chapter, reinforcing the material that you covered. At the end of each chapter, you are presented with a configuration case study that you can use to practice your knowledge of router commands in implementing Remote Access solutions. The last two chapters contain a sample test along with answers and explanations for each correct and incorrect answer, similar to the Exam Cram format. To assist you in your studies, the sample test questions have not only a detailed explanation of why a specific answer is correct, but also explains why the other answers are incorrect. When preparing for the test, it is not only important to know why a specific answer is correct, but why the remaining answers are incorrect: I have found that by providing readers and students with this type of tool, it greatly facilitates their learning and definitely enhances their test-taking skills. Counting each chapter's 20 to 25 questions, the 70 questions on the sample test in the book, and the 100 questions on the CD-ROM, there are over 450 questions to assist you. With this book and the sample questions, you will be more than prepared for tackling the Remote Access test and give you a strong foundation for implementing Remote access solutions for your network. I wish you the best on the long read to achieving your CCNP and CCIE. Richard Deal
