INTRODUCTION

ISDN Demonstrator

ISDN (Integrated Systems Digital Network) is a system which combines telephone and computer networking in a digital medium. The ISDN BRI (Basic Rate Interface) is the interface for individual users to connect to the public telephone network. An ISDN BRI is composed of three separate channels of information called 2B+D, that is, two full duplex Bearer channels and one full duplex Delta channel combined onto a single pair of wire.

The Teltone ISDN Demonstrator is two ISDN BRI connections in a portable housing. The user interface is “U” connection using an RJ45 modular plug. The “U” connection is similar to the interface that is provided by a local telephone service provider (LEC), such as one of the Bell Operating Companies, or an independent telephone company. Using this connection, the user is able to place calls, either voice or data, or both, using the National ISDN-1 signaling standard. AT&T 5ESS Custom provisioning is available as a separate option (ILSATT-01).

ISDN is based upon an OSI (Open System Interconnection) model. The ISDN Demonstrator supports layer 1 (physical operation), layer 2 (data link operation), and Layer 3 (network operation.) Layers 4-7 are considered application layers that use the first 3 layers as a base.

UNPACKING

The ISDN Demonstrator has been developed to make demonstrating of ISDN CPE equipment easier. Integrators, and sales representatives now have an ISDN-BRI server in a box. The ISDN Demonstrator supports ISDNBRI end-to-end operation, multiple Call Control protocols, telephony switch services, and simple functional operation on the desktop or lab bench.

ISDN Demonstrator User’s Manual

CHAPTER 1: QUICK START

The ISDN Demonstrator is easier to operate than most communications devices designed for ISDN-BRI applications. It functions in the background, providing two lines of end-to-end ISDN-BRI service.

Because the Simulator was designed primarily for people who demonstrate, functionally test, or configure ISDN-BRI devices, you do not need to understand ISDN protocols or read the entire User’s Manual to use it. Simply follow the instructions outlined below to successfully demonstrate most ISDN-BRI communications devices and computer applications.

Step 1 Place the Simulator on a flat surface near the ISDN equipment

to be connected.

Step 2 Insert the power cord into the three-pronged outlet located at

the rear of the Simulator. Plug the other end into a standard 115 VAC, 60 Hz wall outlet.

Step 3 Apply power to the Simulator by pressing the power switch -

located at the rear of the Simulator - to the PWR ON position. An internal self-test, lasting about 30 seconds, is performed. The STATUS LED located on the front panel will switch between Red and Green during this self-test. The STATUS LED changes to a continuous solid green if the self-test is completed satisfactorily.

Step 4 The Simulator is configured at the factory for National ISDN-1

protocol. The Simulator is provisioned for default service, as normally practiced for the selected switch type. Most communications devices operate correctly with this provisioning. However, if your communications device does not operate correctly, you may need to change the Simulator’s provisioning. These settings are fully described in Chapter 3. A list of recommended settings for different terminal types (AT&T CUSTOM) is available in the ISDN Demonstrator configuration software.

NOTE: The instructions for many ISDN-BRI

communications devices may specify Switch Provisioning required of the telephone company. Provisioning is a means of configuring the ISDN switch so it knows what kind and how many calls your communications devices can handle, up to the limits imposed by ISDN-BRI technology. Provisioning also specifies which types of Supplementary Services your equipment may request, such as call appearances, display support, etc.

Step 5 A 3.5" diskette is provided with the ISDN Demonstrator to

change the configuration of the ISDN Demonstrator. To install this windows based software, place the diskette in the

40-400-00011, Rev. B

ISDN Demonstrator User’s Manual

appropriate drive and from Windows Program Manager, select FILE, RUN, A:Setup.

Step 6 After the Simulator’s provisioning is established, press

RESTART. The settings are retained in non-volatile memory until you change them. You now have two ISDN-BRI telephone lines ready to provide Circuit Mode Voice (Speech,

3.1 kHz Audio, 7 kHz Audio), and/or Circuit Mode Data (56 Kbs Restricted, 64 Kbs Clear) services on two B Channels.

Step 7 Refer to the instructions supplied by the manufacturer for

installing your communications device or computer application on an ISDN-BRI telephone line. For most devices, you will use a procedure similar to the following:

NOTE: The instructions may specify that your communications device requires power from a secondary source, such as a wall adapter.

Step 8 Confirm your device uses the "U" interface. Use 8-Pin Modular

(RJ-45) telephone cords for the connections between your device and the ISDN Demonstrator.

Step 9 If you have an NT-1 and want to install it between your device

and the Simulator, connect the NT-1 “Line” outlet to the Simulator’s U Interface at either port. Allow several seconds (5-30) for the port’s U-SYNC light to turn green, then connect your communications device to a “Phone” outlet on the NT-1. Most NT-1’s provide two “Phone” outlets, providing a convenient method for connecting two devices at each Simulator port.

Step 10 Next, you may be instructed to program one or more

identification numbers into your communications device or computer application. The numbers may be a Service Profile ID (SPID) and sometimes a telephone number (Directory Number or DN). The Simulator, like an ISDN switch, expects specific SPID’s and DN’s to be assigned to any particular port. When programming these numbers into your communications device, you must assign the number(s) listed in the following table:

First device at Port 1: SPID 0835866101

DN 835-8661 (1-800-835-8661)

Second device at Port 1: SPID 0835866301

DN 835-8663 (1-800-835-8663)

First device at Port 2: SPID 0835866201

DN 835-8662 (1-800-835-8662)

40-400-00011, Rev. B

ISDN Demonstrator User’s Manual

Second device at Port 2: SPID 0835866401

DN 835-8664 (1-800-835-8664)

NOTE: Not all communications devices are programmed with a SPID or DN. Some devices need an additional number called a Terminal Endpoint Identifier (TEI). If you must assign a TEI, use a different number (between 1 and 63) for each device you connect to the Simulator. If automatic TEI assignment is a selectable option, choose it. In short, follow the instructions for your device, using the numbers listed above, when applicable.

Step 11 After any identification numbers are programmed into your

device, it notifies the Simulator using an initialization procedure. If the procedure is successful, and your device is connected to the U interface, the U-SYNC LED will light after synchronization is complete.

NOTE: If the U-SYNC LED does not turn on, the device may need to be rebooted or momentarily disconnected (powered down) and reconnected to make it initialize. If the device did not require SPID programming, the U-SYNC LED may not turn on until you place your first call.

Step 12 Repeat the above steps for additional devices. The Simulator

provides power for up to four communications devices and two NT-1’s. Each communications device must be programmed with a different SPID and/or DN.

Step 13 If you later need to rearrange the connections between the

Simulator and your devices, disconnect the devices from the Simulator, press RESTART on the Simulator’s power switch, wait for the STATUS LED to turn to a solid green, then reconnect your devices. If you move a device from one port to another, its SPID and DN must be reprogrammed using available numbers from Table 1. You do not need to restart simulation if you change a device’s SPID or DN when it remains at the same port.

IMPORTANT: Some devices let you change the ISDN protocol to support the type of ISDN switch the telephone company has installed. If you change your device’s protocol, you must change the Simulator’s Switch Type configuration to match. If you change any one device’s ISDN protocol, then all devices connected to the Simulator must be configured for that protocol.

Step 14 Now you can operate your devices as recommended by the

manufacturer.

40-400-00011, Rev. B

ISDN Demonstrator Operation

When the STATUS LED is a solid green, you can use your communications devices or computer applications as if connected to the telephone company’s ISDN-BRI service.

In general, your ISDN-BRI device will operate the same as conventional telephone equipment, with the obvious exceptions that call processing occurs more rapidly and that voice, high-speed data, and packet mode data may be sent and received simultaneously.

To call from one device to another, you must connect at least two devices to the Simulator. To place a call from device 1 to device 2, dial either the local DN or long distance DN associated with device 2. For example, to call from device 1 (DN= 835-8661) to device 2 dial the local Directory Number 8358662 or the long distance number 1-800-835-8662.

If you dial one of the valid Directory Numbers, but no device was assigned to that number, you will hear a ringing tone. If you dial a number assigned to a device that is unable to accept the call, you will hear busy tone and be disconnected after approximately 45 seconds. If you dial a number that is invalid, you will hear a reorder tone (fast busy signal), which means the Directory Number is not in service.

ISDN Demonstrator User’s Manual

If you dial the number correctly and the device is able to accept the call, the called device begins alerting (rings). When the call is answered, a connection is established between the devices. You may then talk, transfer files, share computer applications, video conference, exchange e-mail, or perform any other service or feature your ISDN-BRI devices or computer applications support.

If your device supports putting a call on hold or placing multiple calls, you can make additional calls to other devices. You can also make calls in either direction. When you have completed the demonstration, hang up all calls to release their resources.

ISDN-BRI supports up to two connected voice and/or data calls on one line using the B Channels. More than two calls may be present, but any call exceeding the limit of two connected calls must be placed on hold. Some devices, particularly those that support video conferencing or LAN adaptation, need both B Channels for a single call.

If your communications device requests any of these services, the Simulator provides the necessary processing and resources. A special case, which uses the D Channel and X.25 packet data transmission is also supported and may occur while both B Channels are connected. To enable this service, see Chapter 3 section on D Channel X.25 Packet Handling Function.

Some limitations apply to all ISDN-BRI communications, however. For example, if two devices are connected to a single line and you establish a call between them, both B Channels at that line are allocated to connect the call. In other words, both B Channels are “busy” during one connected call. Consequently, any device that uses two B Channels for a single call, such as

40-400-00011, Rev. B

ISDN Demonstrator User’s Manual

a video conferencing application, cannot connect to another device on the same line.

Another limitation occurs when attempting to place a call to a device that does not support the requested call type. For example, a call placed from an ISDN data terminal to an ISDN voice telephone will be rejected by the telephone.

In some cases, the call type and number of channels are satisfied and the called device answers the call, but the calling application is not compatible with the called application. For example, not all video conferencing applications use the same data encoding. Or, a Terminal Adaptor that converts ISDN to RS-232 may answer a data call that is carrying FAX information. A well-designed application determines that it cannot process the data and releases the call. Otherwise the user must hang up.
