About ISDN

ISDN uses digital technology to connect to the public telephone network. Using the existing copper wire and public telephone network infrastructure, ISDN provides for existing voice services and high-speed, dial-up data service.

Networks using ISDN communicate more efﬁciently than those using analog lines. This is due to the relatively low cost of ISDN, the fact that digital lines are relatively free of the random noise associated with analog lines, and the high communication speeds that can be achieved. ISDN Basic Rate Interface (BRI) lines can reach speeds of up to 128 thousand bits per second (Kbps). A typical high-speed modem can only send data over an analog line at up to 28.8 Kbps.

You can convert almost any existing regular telephone line to ISDN by ordering ISDN service for that line. In most cases, no rewiring is necessary for the conversion and no special equipment is needed to use the converted line with your Netopia ISDN Modem. (Keep in mind that if you convert an analog line to an ISDN line, you will not be able to directly connect analog devices to the ISDN line in most cases.)

ISDN and the Netopia ISDN Modem

If you’ve been using an ordinary modem to dial into analog data services, such as a corporate LAN or online service, you can continue to do so with your digital ISDN line. Simply connect your analog modem to one of the analog device ports on the Netopia ISDN Modem and continue to use your analog devices in the same fashion as before.

The Netopia ISDN Modem will convert the analog signal to a digital signal for transmission over the ISDN line in such a way that it can be retransmitted by the public switched network to an analog device.

Terms used in this user’s guide

The following ISDN-related terms are used in this user’s guide:

Basic Rate Interface (BRI):

order from the ISDN service provider. A BRI ISDN line has two B channels and a D channel. The B channels carry data at 56 Kbps or 64 Kbps, and can be used by the applications you use to access the Internet. The D channel is reserved for call setup and signalling.

D channel

Switch:

from the telephone company’s local central ofﬁce. You must know the type of switch—sometimes referred to as

conﬁguration Directory number (DN):

the ISDN line you order (the directory number is also referred to as the “telephone number” in this user’s guide). Depending on the type of switch on your line, there may be one directory number for both B channels, or one for each B channel.

The massive computer that controls your telephone line

—on your line to properly conﬁgure the ISDN modem.

BRI is the type of ISDN service you will

B channels

ISDN BRI

switch

The actual phone number associated with

SPID:

The Service Proﬁle ID generally looks like the directory number with some extra digits (the TID) appended to it. The number of SPIDs received with BRI service can vary from none to two.

TID (Terminal ID): This one- or two-digit number is associated with the SPID. It’s usually 1 or 01 for the ﬁrst SPID and 2 or 02 for the second SPID, but it can vary in form.

If you encounter other unfamiliar terms, check the glossary.

Page 18

2-6 Netopia ISDN Modem User’s Guide

SPID formats

The exact format of ISDN SPIDs is sometimes a point of confusion. This is because several formats exist, and some formats allow variations.

The table below displays the general SPID formats for some of the types of ISDN switch conﬁgurations supported by the Netopia ISDN Modem. The formats shown are a subset of possible SPID formats, but in most cases they should work.

In the following table, xxxxxxx represents the directory number assigned to your ISDN line, and yyy represents your area code.

Switch SPID format

AT&T 5ESS custom (multipoint)

National ISDN-1 on AT&T 5ESS (multipoint)

National ISDN-1 on Northern Telecom DMS-100

Note: AT&T 5ESS custom point-to-point switches have no SPIDs and are not represented in the table above. However, this type of switch conﬁguration is supported by the Netopia ISDN Modem.

Example SPIDs If your ISDN line is controlled by a DMS-100 using National ISDN-1,

and your directory numbers are given as (415)234-5678 and (415)234-5679, your SPIDs are 4152345678100 and

4152345679200. Alternately, your SPIDs can be 41523456780100 and 41523456790200.

Preparing for an ISDN line

When you order an ISDN line, you will exchange information with the ISDN service provider about the kind of service you need. The provider, in turn, will give you some information about your line that will be useful when you conﬁgure your Netopia ISDN Modem.

There are a few things to do before you can order an ISDN line:

■ Find an ISDN service provider

■ Decide on a type of ISDN line

■ Choose a phone line

■ Use your ISDN worksheet

These are explained in the corresponding sections below.

Setting Up ISDN Service 2-7

Find an ISDN service provider

ISDN service is typically provided by local telephone companies. In certain regions, there may be other types of companies providing ISDN service, such as long distance telephone companies. In this user’s guide, we’ll refer to the ISDN service providers as telephone companies.

If you are unsure of who provides ISDN service in your area, start by contacting your local telephone company (refer to the list of contact numbers for telephone companies that appears later in this chapter). Ask for the ISDN service representative or for someone in the company’s marketing or business services ofﬁce.

Regardless of who you choose for ISDN service, the basic process of setting up an ISDN line should be the same.

Page 20

2-8 Netopia ISDN Modem User’s Guide

Decide on a type of ISDN line

An ISDN line can be conﬁgured to carry data only, or both data and voice.

Choose a phone line

To order an ISDN line, you must either designate an existing telephone line to be converted, or order a new line to be installed. There will probably be an additional charge if you add a new ISDN line. However, if you convert an analog line to an ISDN line, you will not be able to directly connect analog devices to the ISDN line in most cases.

Regardless of your choice, make sure there is a wall jack for the line you choose near where you intend to install your Netopia ISDN Modem.

Use your ISDN worksheet

The ISDN Worksheet at the end of this chapter (see page 2-18) contains sections where you can note important information about your ISDN account. You may want to photocopy the ISDN Worksheet and ﬁll in the copy.

Note: The ISDN Worksheet is for your convenience only. You may receive forms containing similar information from your telephone company. In any case, the ISDN Worksheet is not an application for an ISDN line nor a substitute for the forms your telephone company uses.

Fill in section 1 of the worksheet once you ﬁnd out exactly who you’ll order your ISDN line from. Fill in as much of section 2 as you can before calling your telephone company. The information in section 3 can only be ﬁlled in after you order your ISDN line.

Page 21

Be sure to check the accuracy of the information you enter on the worksheet. Some of it will be needed later when you conﬁgure your Netopia ISDN Modem.

It’s also a good idea to have the worksheet available if you call Farallon technical support. The information on the sheet may help a Farallon technician answer your questions more quickly.

Ordering your ISDN line

This section contains the information you’ll need to successfully order an ISDN line.

Read this section through before contacting your telephone company. Then refer to it when you actually order your line.

The ﬁrst step in ordering your ISDN line is to prepare for the questions your telephone company may ask, such as:

Setting Up ISDN Service 2-9

■ Will you be using an existing telephone line or need a new one?

■ Where is the line located?

■ Who is the contact person at that location?

■ Who will be billed for the line or should this line be added to an

existing account?

■ Should the service (or number) be listed?

Use section 2 of the ISDN Worksheet to record the answers to these questions before calling your telephone company. Your telephone company may also ask other questions about the type of service you want.

Page 22

2-10 Netopia ISDN Modem User’s Guide

Contacting the telephone company

Below is a list of items that can help you order your ISDN line more easily. These items correlate with items in section 3 of the ISDN Worksheet (see page 2-18).

Depending on your situation, some of these items may not apply to your order, and all of the items may not be dealt with by your telephone company at the same time. In addition, there may be other issues you will need to ask the telephone company about.

When an item in this list generates information that should be entered in your worksheet, be sure to do so.

First, read through this list and become familiar with its contents. Then call your telephone company and refer to the items in the list during the ordering process.

1. Call your telephone company. Refer to the table below for your telephone company’s phone number.

2. ISDN line conﬁguration. Your telephone company may have the Netopia ISDN Modem on a list of supported products that have been tested with a particular ISDN line conﬁguration. If your telephone company conﬁrms that the Netopia ISDN Modem is on that list, then it will know how to set up your line.

Note: If your telephone company does not recognize the Netopia ISDN Modem, you should read “General ISDN line

conﬁguration” on page 2-14.

Page 25

Setting Up ISDN Service 2-13

3. Type of switch conﬁguration used on your line. You must receive this information from your telephone company to properly conﬁgure the Netopia ISDN Modem. The switch should be one of the types supported by the Netopia ISDN Modem:

■ AT&T 5ESS custom

■ Northern Telecom DMS-100 or Siemens EWSD

■ AT&T 5ESS

4. Directory numbers and SPID (service proﬁle identiﬁer) numbers. This information may be provided to you at a later time,

after your line has been set up. There may be one or two directory numbers, and one or two SPIDs. If the switch on your line is an AT&T 5ESS custom point-to-point, you will receive no SPIDs. It’s very important that you record this information accurately.

Note: Regardless of the number of directory numbers and SPIDs you receive, your line should be conﬁgured to allow the Netopia ISDN Modem to use both B channels at once.

5. Circuit ID number. Your line has a unique physical address called a circuit ID. Y ou should obtain this number from your telephone company and record it on the worksheet. The circuit number can be useful for locating your line and its associated circuit in case of a problem.

6. Long-distance company to be used on your ISDN line. When the Netopia ISDN Modem makes long distance calls on your ISDN line, you will be billed by a long distance telephone company. Make sure that you have the long distance company of your choice.

Page 26

2-14 Netopia ISDN Modem User’s Guide

General ISDN line conﬁguration

What if your telephone company does not recognize the Netopia ISDN Modem? You can still use the ISDN Worksheet, but follow these steps:

1. Ask for a standard Basic Rate Interface (BRI).

2. Ask the telephone company representative what type of switch the company will use for your line: AT&T 5ESS custom, Northern Telecom DMS-100/Siemens EWSD, or AT&T 5ESS. Note this information on your ISDN Worksheet for later use.

Note: NI-1 can appear on an AT&T 5ESS or a Northern Telecom DMS-100.

3. Locate your telephone company’s ISDN switch type in the table below. Provide the switch parameters to the representative.

Check to make sure the switch type and SPID(s) the software conﬁgures match the settings the telephone company gave you.

Step 10:

Conﬁguring call routing

Step 11: Conﬁguring the

B channel data rate

The call routing option (the Phone Port and Phone Port 2 check boxes in the Number 1 and Number 2 areas) lets you route calls to analog devices connected to the analog device ports. If you have more than one telephone number, you can route calls from either number to Phone Port 1 or Phone Port 2. By default, all the Phone Port boxes are checked. This allows calls to both ISDN telephone numbers to simultaneously ring devices attached to both ports. For more information, see the “Call routing to the analog device ports”

section on page 6-13.

The conﬁguration dialog box lets you conﬁgure call routing for Phone Number 1 and Phone Number 2.

10. Check the box beside the phone port(s) to which you want to route calls from telephone number 1 and telephone number 2.

You can conﬁgure the B channel data rate for 56 or 64 Kbps. The data rate you select should match your telephone company’s B channel rate (for information, see the “ISDN Worksheet” section

on page 2-18.) By default, the B channel data rate on the Netopia

ISDN Modem is set at 56 Kbps. If this setting doesn’t match your telephone company’s rate, you need to change the setting.

Page 46

If you select the T oll Saver option in the conﬁguration dialog box, T oll Saver will be applied to all outgoing ISDN calls. You must disable the Toll Saver feature to place calls to devices that do not support this feature.

11. To change the B channel data rate, select either 56, 64, or Toll Saver for the B Channel Rate. For more information about Toll Saver, see the “Placing a Toll Saver call” section on page 6-8.

Step 12: Enabling and

disabling Multilink PPP

Steps 13 to 14:

Completing the

conﬁguration

Multilink PPP allows a maximum digital connection of up to 128 Kbps by virtually linking two 56 Kbps or 64 Kbps B channels.

12. Click in the Multilink check box in the PPP area (lower-right corner) to toggle Multilink PPP. If the box is checked, Multilink PPP is on. For more information about Multilink PPP, see the “Using

Multilink PPP” section on page 6-4.

13. Click the Update button to download the parameters displayed in the dialog box to your ISDN modem.

14. Check the status area to verify the conﬁguration. If the parameters were conﬁgured accurately and the ISDN modem is ready to send and receive calls, the status area ﬁelds should contain the information shown below. Note that you do not conﬁgure the Terminal Endpoint Identiﬁer (TEI) numbers, they are generated automatically by the telephone company.

■ Layer 1: UP

■ SPID 1: Init

■ TEI 1: Number from 0 to 127

■ SPID 2: Init (if required)

■ TEI 2: Number from 0 to 127 (if required)

3. In the B1 Channel DN entry ﬁeld, enter the primary DN.

4. Check the box beside the phone port(s) to which you want to route calls from telephone number 1. This option lets you route calls to analog devices connected to the analog device ports. For information about call routing, see the “Call routing to the

analog device ports” section on page 6-13. (This option is only

available for the Netopia ISDN Modem Model 412.) If you do not have a secondary SPID and DN, skip steps 5 through 7.

5. In the B2 Channel SPID entry ﬁeld, enter the SPID associated with the secondary directory number (DN).

6. In the B2 Channel DN entry ﬁeld, enter the secondary DN.

7. Check the box beside the phone port(s) to which you want to route calls from telephone number 2. (This option is only available for the Netopia ISDN Modem Model 412.)

Page 72

5-8 Netopia ISDN Modem User’s Guide

Note: If you want to change the settings displayed in the window to the settings currently deﬁned in the Netopia ISDN modem, click the Revert button. This button is useful if you make a mistake entering new settings in the window and want to revert to the old settings.

8. Check the Enable Auto Answer box to turn on the auto answer feature. When Enable Auto Answer is active, the ISDN modem automatically answers incoming data calls. You might want to use this feature if you have callback set up in your communications software or you want to receive incoming data calls over your Netopia ISDN Modem.

9. Click the Set Modem button to conﬁgure the Netopia ISDN Modem with the new settings. Generally, you will only need to set the parameters in the Easy Setup window once.

Note: The changes you make in the Easy Setup window are not sent to the ISDN modem until you click the Set Modem button. When the settings on the Easy Setup and Advanced windows exactly match the ISDN modem’s settings, the Set Modem button is disabled.

If the parameters match those registered at the telephone company ISDN switch, the D channel LED lights for a few minutes, ﬂashes for several seconds, and then turns off. If the LED continues to ﬂash or remains lit, see Chapter 7, “Troubleshooting.”

If the D channel LED indicates a proper connection to the ISDN switch, you can place your ﬁrst call. Go to the “Placing calls with a

Macintosh computer” section on page 5-20.

Page 73

Conﬁguration using a Macintosh computer 5-9

The Advanced window

The Advanced window contains three main areas:

■ B Channels

■ Enable Multilink PPP

■ Serial Port

In most cases, you’ll probably only need to modify the Data Rate setting, which appears in the B Channels area.

Note: The changes you make in the Advanced window are not sent to the ISDN modem until you click the Set Modem button. When the settings on the Advanced and Easy Setup windows exactly match the ISDN modem’s settings, the Set Modem button is disabled.

Page 74

5-10 Netopia ISDN Modem User’s Guide

B Channels

The B Channels area lets you select options for your two ISDN B channels.

Data Rate. Choose the B-channel data rate you want from the Data Rate pop-up menu. The data rate options are 56 Kbps and 64 Kbps (the two data rates ISDN supports). Not all telephone services support the 64 Kbps data rate. Select the data rate used by your telephone company.

Protocol. The Protocol pop-up menu lets you choose the transport protocol you want. The protocol options are QuickSelect, Async/Sync PPP Convert, and V .120. In most cases, you should use the QuickSelect protocol. QuickSelect allows the Netopia ISDN Modem to automatically detect the protocol in use on the ISDN line and adapt to that protocol. Also, when QuickSelect is active, the modem converts asynchronous Point-to-Point (PPP) information into synchronous (HDLC-based) PPP information. If you select either the Async/Sync PPP Convert or V.120 protocol, the Netopia ISDN Modem will only use the selected protocol.

Enable Compression. (This option is only available for the Netopia ISDN Modem Model 412.) Check the Enable Compression box to turn on data compression. Data compression is a method of reducing the size of data without losing any of the information. Models 412 and 612 of the Netopia ISDN Modem automatically use Stac data compression to compress data to improve data transfer times. To take advantage of data compression, the device you are dialing into must also support data compression. Note that the Netopia ISDN Modem’s data compression will not be used if data compression is in use in your communications application. For more information about data compression, see the “Using data

compression” section on page 6-3.

V.120 Max Frame Size. The V.120 Max Frame Size pop-up menu lets you specify the maximum number of bytes in a V.120 frame. V.120 is an alternative transport protocol to PPP. The available frame sizes range from 240 to 256 bytes. Leave this set at 256 unless your system administrator or Internet Service Provider (ISP) instructs you to specify a different value.

Page 75

Conﬁguration using a Macintosh computer 5-11

V.120 Frame Type. The V.120 Frame Type pop-up menu lets you choose either I or UI as the V.120 frame type. Leave this set at I unless your system administrator or ISP instructs you to specify UI.

Enable Multilink PPP

The Enable Multilink PPP area lets you enable and disable the modem’s Multilink PPP and dynamic bandwidth allocation features and deﬁne certain parameters for Multilink PPP. For more information, see the “Using Multilink PPP” section on page 6-4.

Enable Multilink PPP. Check the Enable Multilink PPP box to turn on the Multilink PPP feature. When Multilink PPP is on, the Netopia ISDN Modem can combine two B channels to allow up to 128 Kbps of data to pass through the ISDN line. You must enable this option in order to use the Dynamic Bandwidth Allocation feature.

Dynamic Bandwidth Allocation. Check the Dynamic Bandwidth Allocation box to turn on the Dynamic Bandwidth Allocation feature. When Dynamic Bandwidth Allocation is on, you can initiate a phone conversation after you have established a dual B channel connection. When you initiate the phone conversation, the modem disconnects one of the B channels and uses it for the voice call. For more information, see the “Using Dynamic Bandwidth Allocation”

section on page 6-7.

Second DN. (This option is only available for the Netopia ISDN Modem Model 411.) If necessary, enter a secondary directory number (DN) in the Second DN ﬁeld. The Second DN number is the second number of a destination you call. In most cases, you only need to enter a second directory number if your telephone company uses a switch other than an AT&T 5ESS switch or the destination you are calling does not have its ISDN lines organized in a hunt group. (A hunt group is a collection of phone lines that can be accessed by the same phone number.)

Page 76

5-12 Netopia ISDN Modem User’s Guide

EndPt ID Class. The Endpt (Endpoint) ID Class pop-up menu lets you choose the method by which an Endpoint ID is assigned. An Endpoint ID is a number that some hosts use to keep track of a particular connection. The available Endpoint ID Classes are None, Locally Assigned, Internet Protocol, IEEE 802.1 MAC, PPP Magic Number, and Public Switched Net Directory. In most cases, you should choose Public Switched Net Directory as the Endpoint ID Class unless your system administrator or ISP tells you to specify one of the other classes.

Endpoint ID. In most cases, you should leave this ﬁeld empty and leave the Endpoint ID Class set to its default value of 5 (Public Switched Network Directory Number). With these default settings, the ISDN modem will later automatically ﬁll in the Endpoint Identiﬁer with telephone number 1 (DN1). If your endpoint identiﬁer class is not 5, obtain the identiﬁer from your Internet Service Provider and enter it in this ﬁeld.

CHAP Blocking. Check the CHAP Blocking box to disable the CHAP authentication feature. If this box is checked, the Netopia ISDN Modem will use PAP for authentication. If you are using Multilink PPP, you must check this box to block CHAP authentication.

Serial Port

The Serial Port area lets you specify options for ﬂow control, carrier detect (CD) control, and data terminal ready (DTR) control.

Flow Control. Use the Flow Control pop-up menu to choose the ﬂow control option set up in your communications program. Flow control affects the ﬂow of information between your workstation and the Netopia ISDN Modem. The available ﬂow control options are None, XON/XOFF (software handshake), and RTS/CTS (Request to Send/Clear to Send). RTS/CTS is a hardware handshake protocol. In most cases, you should choose RTS/CTS unless your system administrator or ISP tells you to specify one of the other options.

Page 77

Placing calls with a Macintosh computer

After you conﬁgure your Netopia ISDN Modem using the Macintosh conﬁguration software, you can use your communications software to establish an ISDN connection. You can use any standard communications application that recognizes AT commands. Examples of compatible communications applications include Apple Remote Access (ARA), MicroPhone, or PPP client software, such as InterPPP or FreePPP.

Note: Most areas require you to dial ISDN calls with 11 digits (for example, 1-800-555-1212), even for local calls.

Note that you must use Multilink PPP to make calls using two ISDN B channels. For information, see the “Using Multilink PPP” section

on page 6-4.

Page 85

Chapter 6

Advanced Features

This chapter illustrates how to use the advanced features available in your Netopia ISDN Modem.

This chapter covers the following topics:

■ Placing calls using AT commands

■ Using Multilink PPP

■ Using PPP authentication protocols

6-1

■ Using the analog device ports

■ Receiving data calls

■ Receiving analog calls

The Netopia ISDN Modem uses AT commands and S registers for call management. See Appendix A, “Modem Operation,” for instructions on use of the AT command set and a tabular summary of the AT command lines.

Page 86

6-2 Netopia ISDN Modem User’s Guide

Placing calls using AT commands

Your communications software can communicate with the Netopia ISDN Modem using standard AT commands. To conﬁgure your software, select a Hayes-compatible modem conﬁguration, such as “generic modem,” if no special setting is available for the Netopia ISDN Modem. Refer to your communications software documentation for more details.

When you place a call from a PC or Macintosh computer, the Netopia ISDN Modem recognizes the AT command ATD to dial a digital ISDN data call. Depending on the setting of S register 60, 56 Kbps (default) or 64 Kbps B channel transmission speeds are used. Correct examples of outgoing circuit-switched ISDN modem commands with dial strings are shown below.

■ Dialing with spaces: AT D 1 908 555 7891

■ Dialing without spaces: ATD19085557891

■ Making a Toll Saver (Switched 56) call: ATDD 19085551234

Note: All outgoing calls can be forced to be Toll Saver calls by setting S register 61 to 1.

Enter ATS61=1 Note: Most areas require you to dial ISDN calls with 11 digits

(for example, 1-800-555-1212), even for local calls.

■ Making a Multilink PPP call using two numbers:

ATD19085557891 & 19085555555

You need to use Multilink PPP to make a call using two ISDN B channels with the Netopia ISDN Modem. See the “Using Multilink

PPP” section later in this chapter for details.

Page 87

Using data compression

Compression is a method of reducing the size of data without losing any of the information. Models 412 and 612 of the Netopia ISDN Modem automatically use Stac data compression to compress data to improve data transfer times.

The following check modes are negotiable: None, One Byte Sequence Number, and Extended. The mode is automatically negotiated when a PPP call is placed to another device that supports the compression control protocol. Generally, Extended is the preferred mode. The amount of compression depends on the type of ﬁle being transferred. For example, a text ﬁle compresses better than a binary (application or executable) ﬁle.

Compression is enabled by default. If you enable compression on the ISDN modem and your application uses compression, compression will be disabled in the ISDN modem.

You can use compression in dual B channel Multilink PPP connections and single B channel connections. By using compression on a single B channel, you can achieve performance rivaling a two B channel connection at a fraction of the cost. Because telephone and Internet providers often base charges on the number of B channels used, the Netopia ISDN Modem’s compression feature, which is not available in most other ISDN terminal adapters, lets you achieve nearly the throughput of a two B channel connection at the price of a single B channel connection.

Advanced Features 6-3

Compression is negotiated between your ISDN modem and the device to which you are placing the Multilink PPP call. To take advantage of data compression, the device you are dialing into must also support data compression. If the other device does not support compression, compression will not be implemented.

Using Multilink PPP

The Netopia ISDN Modem supports Multilink PPP , which can link the two ISDN B channels and allow a maximum digital connection of 128 Kbps. Multilink PPP is enabled by default.

If want to use Multilink PPP, make sure:

■ Multilink PPP is turned on in the Netopia ISDN Modem.

■ The serial port of your PC or Macintosh computer supports a

data transmission rate of at least 115.2 Kbps and you’ve set the port speed in your communications software to the maximum available data rate.

■ Both the telephone company service and the Internet Service

Provider (ISP) or LAN dial-in service support two B channel connections.

■ Both you and the destination you are calling are using software

that supports PPP, such as Dial-Up Networking in Windows 95 or InterPPP and FreePPP in the Macintosh operating system.

The following registers control Multilink PPP and are set by your conﬁguration software:

■ S register 80 enables or disables Multilink PPP operation

■ S registers 82 and 83 control Multilink conﬁguration

■ S register 70 controls Dynamic Bandwidth Allocation (DBA) in

Multilink mode

By default, the Netopia ISDN Modem dials the same number for both Multilink PPP channels. If the destination requires a different telephone number to establish a second Multilink PPP channel, then you must include this second telephone number in the dial string. The ampersand character (&) is used to dial two telephone numbers: for example, ATD19085557891 & 19085555555

Note: If you are using a Macintosh computer and a Model 411 Netopia ISDN Modem, start up the ISDN Setup application and enter the second telephone number (DN) in the Second DN ﬁeld in the Advanced window. (For more information, see the “Second DN”

section on page 5-11.)

Page 89

Advanced Features 6-5

By default, the ISDN modem makes calls using the 2 B channels. Note that there may be cost implications to the use of two B channels. Check your usage rates with your service providers, such as the telephone company, Internet Service Provider, or online service provider.

Storing Multilink Endpoint Identiﬁers in S registers

Some Multilink PPP implementations require the use of a Multilink PPP option called the Multilink Endpoint Identiﬁer. The Multilink Endpoint Identiﬁer is a number that the Netopia ISDN Modem uses to distinguish its Multilink PPP calls to a remote router from other Multilink PPP calls. The default Multilink Endpoint Identiﬁer for the ISDN modem is the ﬁrst B Channel’s directory number (as entered in S register 51). The Multilink Endpoint Identiﬁer must be unique in order to identify the ISDN modem’s PPP call. This Multilink Endpoint Identiﬁer also identiﬁes the Multilink session and allows the remote router to add or subtract B Channels to that Multilink PPP session when the ISDN modem requests it.

You probably won’t need to change the default settings for the S registers that control the Multilink Endpoint Identiﬁer (S registers 82 and 83) unless otherwise speciﬁed by your systems administrator or ISP. The defaults are S82=5 (Public Switched Network Directory Number) and S83=(initially empty). (If you have S82 set to the default value of 5, leave S83 empty. The ISDN modem will later automatically ﬁll in S83 with the directory number entered in S register 51.) If you do change the Multilink Endpoint Identiﬁer, however, make sure the number you specify is a “unique” number to the equipment you are dialing into so the equipment will not confuse your Multilink PPP call with another call.

Page 90

6-6 Netopia ISDN Modem User’s Guide

■ S register 82 stores the Multilink Endpoint Identiﬁer Class

value. Valid class values are listed in Appendix A, “Modem

Operation.”

■ S register 83 stores the actual Multilink Endpoint Identiﬁer.

Note: This option is not required in most cases, so these registers typically do not have to be changed. Your system administrator or Internet Service Provider will provide you with a Multilink Endpoint Identiﬁer if it is required.

Using PPP authentication protocols

The Point-to-Point protocol (PPP), when used with Dial-Up Networking, FreePPP, and other software, allows for authentication of users dialing into hosts or routers. While the connection between a user and host is being established, the host may request authentication before the link is established. In addition, the host will request a certain type of authentication: typically Password Authentication Protocol (PAP) or Challenge Handshake Authentication Protocol (CHAP). PAP veriﬁes the user’s plain text ID and password. CHAP is a stronger authentication method. It uses encryption and may repeatedly verify the user’s ID any time during the connection.

In response to the host’s request, the client software indicates whether or not it supports the same type of authentication. If it does not support the same type of authentication, it may request an alternative type of authentication. (For example, if the host requests CHAP, but the client software only supports PAP, the client software will request PAP.) After establishing a type of authentication, the process of verifying the user begins.

Both PAP and CHAP are built into the Netopia ISDN Modem and are conﬁgured by your PPP software. To enable CHAP using Windows 95 Dial-Up Networking, check the Require encrypted password box in the Server Types dialog box.

Page 91

Note: You cannot use CHAP when you make Multilink PPP calls. CHAP is disabled by default, so this should not be a problem. However, if CHAP is enabled, before you make a Multilink PPP call, you must disable CHAP by sending the command, ATS84=1, to the ISDN modem using your communications application. If you are using a Macintosh computer, use the ISDN Setup application to turn off CHAP. For information, see the “CHAP Blocking” section on

page 5-12.

Using Dynamic Bandwidth Allocation

The ISDN modem supports Dynamic Bandwidth Allocation (DBA). When Dynamic Bandwidth Allocation is enabled (by default), you can place an analog (voice) call from a device that is attached to one of the analog device ports while a Multilink PPP call is active. The ISDN modem will automatically use one of the B channels for the analog call. Once the analog call ends, the ISDN modem automatically reestablishes that channel for Multilink PPP operation. Your voice call will be billed at ISDN rates because the signal is carried over your ISDN line.

Advanced Features 6-7

Note: If you are on the receiving end of a Multilink PPP call and you place a voice call, one of the B channels will be used for the voice call. However, when the voice call is ﬁnished, the B channel used for the voice call cannot be returned to the Multilink PPP call. The B channel can only be returned to the call if you initiated the Multilink PPP call.

Placing a Toll Saver call

The Toll Saver feature allows you to place a data call using a voice channel, thereby saving the extra cost often associated with placing a data call. By combining the Toll Saver feature with the Netopia ISDN Modem’s built-in data compression, you can transfer up to 128 Kbps of data for the cost of a single voice call.

Note: T o place a Toll Saver call, the device you are dialing into must be capable of generating the 3.1 kHz tone necessary for disabling the echo cancellers on the line. Also, check with your Internet Service Provider to verify that this feature (also called “56 permissive calls”) is supported.

T o manually dial a Toll Saver call, send the following AT command to the Netopia ISDN Modem:

ATDD <telephone number> for example: ATDD 14085551234

About QuickSelect

To conﬁgure the ISDN modem to send all outgoing calls as Toll Saver calls, set S register 61 to 1.

The ISDN modem’s QuickSelect feature automatically converts asynchronous Point-to-Point Protocol (PPP) into synchronous (HDLC-based) PPP. This allows for connections to communication servers and routers that have Basic Rate Interface (BRI) ISDN, Primary Rate Interface (PRI) ISDN, or T1 access lines.

Using the Netopia ISDN Modem’s QuickSelect feature, you do not have to manually select the proper protocol for each ISDN call. With QuickSelect enabled, the ISDN modem automatically detects and uses the required protocol. QuickSelect is enabled by default.

Optimizing serial port performance

The serial port speed of most PC and Macintosh computers limits the computer’s maximum data transmission rate. Typically, PCs and Macintosh computers are limited to a maximum transmission speed of 115.2 Kbps. However, advanced serial cards and drivers are available to boost the serial port speed up to 230.4 Kbps.

PC serial ports

For sustained performance at data rates higher than 57.6 Kbps, Farallon recommends that your PC’s serial COM port be equipped with a 16550 universal asynchronous receiver/transmitter (UART).

To determine what type of UART is installed in your PC, type msd at the DOS prompt to run the Microsoft Diagnostic Program.

Advanced Features 6-9

You can use software utility tools to optimize the performance and reliability of the serial port through the 16550 UART. Recommended tools include WFXCOM.DRV, available on a number of BBS and ftp sites, or TurboCom, available from Paciﬁc CommWare, Inc., of Ashland, Oregon (541-482-2744).

Macintosh serial ports

Macintosh models equipped with 680x0 processors are generally limited to serial port speeds of 57.6 Kbps. Power Macintosh and AV models equipped with Apple’s GeoPort technology can generally support serial speeds of 115.2 Kbps or higher. For optimal performance, Farallon recommends installing Apple’s Serial DMA extension, version 2.02 or later, which requires Macintosh System

7.5 or later. If you are using System 7.5.3 or later, the correct version of the serial driver is already installed in your system and you do not need to add this extension. For more information about serial connections, see the “Conﬁguration using a Macintosh

computer” section on page 5-2.

About autobaud

Autobaud automatically detects your computer’s serial port current data rate, up to 115.2 Kbps (autobaud does not support 230.4 Kbps transmissions).

To set the baud rate to the maximum speed of 230.4 Kbps, ﬁrst make sure your computer’s serial port and your communications software support 230.4 Kbps transmission speed. Then send the following command to the Netopia ISDN Modem: AT $B 230400. Change the setting of your application program to 230400 bps. If you are using a Macintosh computer, start up the ISDN Setup application and set the baud rate to 230.4 Kbps. (For more information, see the “Conﬁguration using a Macintosh computer”

section on page 5-2.)

If you are using the Windows conﬁguration program, autobaud must be enabled to access the Netopia ISDN Modem conﬁguration dialog box. If the baud rate is set to a speciﬁc rate (such as 230.4 Kbps), you will not be able to access the conﬁguration dialog box.

Before you set the ISDN modem to a speciﬁc baud rate, make sure the conﬁguration dialog box parameters are set correctly. To return to autobaud mode, set the baud rate of your communications program to the baud rate you deﬁned for the ISDN modem and then send the following AT command: AT$B0. This sets the ISDN modem to autobaud. If you are still unable to access the conﬁguration dialog box, press and hold down the “a” key on the keyboard and press the RESET key on the back of the ISDN modem. Hold the “a” key down until the ISDN modem comes back on line and then release the key.

Page 95

Using the analog device ports

If you have analog touch-tone telephones, answering machines, fax machines, external analog modems, or other analog telephone devices, you can connect them to the two RJ-11 modular jacks on the Netopia ISDN Modem. The two ports are located above the telephone icon on the back panel of the ISDN modem.

The Netopia ISDN Modem does not support pulse-dialing (rotary) telephones.

To place an analog call, simply take the telephone handset or external fax machine off the hook, wait for a dial tone, and dial the destination telephone number. Similarly, to use an analog modem, connect the analog modem to one of the analog device ports and use the modem the same way as if it were connected to a regular phone line. See the next section for information about receiving analog calls.

Note: The Netopia ISDN Modem is designed to operate with telephones that are compatible with the original AT&T 2500 touch-tone telephone standard. You may operate up to three compatible touch-tone devices per analog device port using modular telephone cable of up to 200 feet in length. Although the ISDN modem may function satisfactorily at longer cable distances with more than two attached telephones, proper operation at longer cable distances is not guaranteed in all situations.

Advanced Features 6-11

Some telephone equipment, most notably speaker phones that draw large amounts of power, may not work at all on the ISDN modem’s analog device ports. These devices do not conform to the power speciﬁcation of the AT&T 2500 touch-tone telephone standard, and their operation is not guaranteed.

Receiving analog calls

The Netopia ISDN Modem can receive incoming analog calls, such as calls from an ordinary fax machine or pay phone. The ISDN modem will direct the call to devices connected to the two analog ports.

You can receive an analog call under the following scenarios:

■ If you are using one B channel for a digital data call (such as a

connection to your Internet Service Provider), you can receive an analog telephone call on the other B channel.

■ If you are using one B channel for a digital data call, and

someone calls the number associated with the B channel you are using, the incoming analog call will receive a busy signal unless your local switch is an AT&T 5ESS switch. An A T&T 5ESS switch will let the incoming analog call roll over to the available B channel.

You cannot receive an analog call:

■ When you are using both of the B channels for two analog calls,

an analog call and a digital data call, or for a Multilink PPP digital data call.

Note: An option called Flexible Call Offering (FCO) or Additional Call offering (ACO), which is included in the ISDN service from some telephone companies, allows you to receive an incoming call while a dual-channel Multilink PPP call is in progress.

Page 97

Advanced Features 6-13

Call routing to the analog device ports

Because ISDN supports two independent B channels, you can use each channel separately. You can use the Netopia conﬁguration software to route calls on telephone numbers 1 and 2 to speciﬁc analog device ports. By default, incoming calls to ISDN telephone numbers 1 and 2 ring both analog device ports simultaneously.

Using the Netopia conﬁguration software, check the box beside the phone port(s) to which you want to route calls from telephone number 1 and telephone number 2. In the conﬁguration software, the analog device ports are called Phone Port 1 and Phone Port 2.

Example You might want to use call routing to exclusively assign a telephone

number to a device. For example, suppose you have an analog telephone attached to Phone Port 1 and a fax machine attached to Phone Port 2. To route incoming calls from telephone number 1 to the telephone and calls from telephone number 2 to the fax machine, you would do the following in the Netopia conﬁguration software. In the Number 1 area, check the Phone Port 1 check box and uncheck the Phone Port 2 check box (this routes incoming calls on telephone number 1 to Phone Port 1). In the Phone Number 2 area, uncheck the Phone Port 1 check box and check the Phone Port 2 check box (this routes incoming calls on telephone number 2 to Phone Port 2).

If both ports are selected for a telephone number, incoming calls ring devices attached to both ports simultaneously.

If you have only one phone number for your ISDN line and two analog devices connected to the analog device ports, check the Phone Port 1 and Phone Port 2 boxes in the Number 1 area. Calls to telephone number 1 will ring both devices, allowing you to answer the call on either device. Note, however, because you have only one telephone number, you cannot place or receive more than one call at a time.

Conﬁguring call routing” on page 4-7. For information on conﬁguring

call routing on a Macintosh computer, see “The Easy Setup window”

on page 5-6.

The table below shows how the call routing settings you specify in the Netopia conﬁguration software determine how incoming calls on phone number 1 and phone number 2 are routed to the two analog device ports (Port 1 and Port 2). (If the box beside the port is checked, calls are routed to that port.)

Receiving data calls

The Netopia ISDN Modem can receive incoming circuit-switched data calls from other Netopia ISDN Modems or from ISDN devices and Switched 56 equipment.

■ If you are using one B channel, and you receive a data call on

the number associated with the other B channel, the incoming data call will ring through.

■ If you are using one B channel, and you receive a data call on

the number associated with the B channel you are using, the incoming data call will receive a busy signal unless your local switch is an AT&T 5ESS switch. An AT&T 5ESS switch will let the incoming data call roll over to the available B channel.

■ If both B channels are in use, you cannot receive a data call.
