Chapter 1: Introduction • CSU (Channel Service Unit) (For more information, see North America T1/PRI Line on page 17). Software Drivers You can install only one iSPAN-PRI PCI ISDN adapter per system. Each adapter requires the following drivers: • WAN adapter driver for Windows NT: the basic driver required to support the adapter • RAS Support: the driver required to support Microsoft Remote Access Service over ISDN. Enables the transport of TCP/IP, IPX/SPX, and NetBEUI protocols over ISDN lines.
Software Drivers The complete iSPAN-PRI software is stored on a single diskette or a CD-ROM included in the adapter package.
2Installing the Hardware 2 Overview You can install the iSPAN-PRI adapter in any suitable PCI expansion slot. To install your adapter, follow these basic steps: 1. Verify that the system meets minimum requirements. 2. Inspect the adapter. 3. Install the adapter in a host expansion slot. 4. Connect the adapter to an MVIP Bus, if required. The tools required are a grounding strap and a #1 Phillips head screwdriver. Both are delivered with the product and are included in the packaging.
Inspecting the Adapter CAUTION The adapter is packed in an antistatic bag to protect it during shipment. Keep the adapter in its protective antistatic bag until you are ready to install it in the host computer. To prevent damage to the adapter due to electrostatic discharge, wear a grounding strap on your wrist or ankle and handle the adapter only by its edges. Do not touch its components or any metal parts other than the faceplate.
Chapter 2: Installing the Hardware Installing the Adapter WARNING Your computer operates at voltages that can be lethal. Follow all cautions and warnings in this installation procedure, both to protect yourself and prevent damage to your computer. Use only tools with nonconductive handles, or tools coated with, covered with, or made with nonconductive materials.
Installing the Adapter 1. Turn off the computer’s power switch, and unplug the unit from its power source. Figure 2-1. Unplugging the Computer 2. Disconnect all cables connected to the main system unit, and remove the computer cover according to the manufacturer’s instructions.
Chapter 2: Installing the Hardware Figure 2-2. Removing the Computer Cover 3. Locate a suitable PCI expansion slot, and remove the screw that attaches the expansion plate to the computer. Save the screw for Step 6. CAUTION If you plan to connect the adapter to an MVIP bus, the location of the adapter depends on the other MVIP adapters. See Connecting the Adapter to an MVIP Bus on page 14 for instructions before proceeding with the installation process.
Installing the Adapter 4. Remove the expansion plate. Figure 2-3.
Chapter 2: Installing the Hardware 5. Carefully remove the adapter from its antistatic bag, and position the adapter in the PCI expansion slot. Align the adapter’s connector pins with the slot’s receptacle; then press gently but firmly on the board to seat it in the slot. 6. Attach the adapter with the screw removed in step 3. Figure 2-4.
Connecting the Adapter to an MVIP Bus NOTE If you need to connect the adapter to other MVIP telephony processing adapters in the cabinet, such as voice, data, fax, video or image processing adapters, and have not already done so, see Connecting the Adapter to an MVIP Bus on page 14. 7. Replace the computer cover. You are now ready to connect the adapter to the appropriate PRI line, as described in Connecting to the Line on page 17.
Chapter 2: Installing the Hardware Requirements for MVIP Bus Electrical Termination For systems with five or fewer MVIP bus connections and less than 90 pF load on the clock lines, it is adequate to place the circuit board that is the master clock source at one end of the cable and electrically terminate the MVIP bus only on the circuit board located at the other end of the cable. NOTE The iSPAN-PRI adapter is generally the master clock source, because it is connected to the network.
Connecting the Adapter to an MVIP Bus How to Configure MVIP Electrical Termination on the iSPAN-PRI The factory default configuration for the iSPAN-PRI adapter does not require jumpers. If the adapter does not have to be electrically terminated, do not insert any jumpers into the 2-pin connectors. If this is the last board in a multiple MVIP bus configuration, the iSPAN-PRI adapter requires electrical termination in the MVIP bus.
3Connecting to the Line 3 Overview The type of line your carrier provides depends on whether you are in North America or Europe. This chapter provides the following information required to connect your adapter to the line: • connection methods and requirements for connecting to a North American T1/PRI line • connection methods and requirements for connecting to a European E1/PRI line • summary of steps to connect the adapter to the network. If you are in North America, continue with the next section.
North America T1/PRI Line If the distance is longer (up to 6200 feet or 1800 meters), you need to connect the adapter in a DS1 configuration. In this configuration, a Channel Service Unit (CSU) must translate the short haul DSX1 interface in order to support the longer distance. The iSPAN-PRI adapter optionally supports an internal CSU. In this case, you can connect the adapter directly to the T1/PRI line, also in a DS1 configuration.
Chapter 3: Connecting to the Line WARNING To avoid harming the WAN, you must first contact your carrier for approval before connecting the adapter to the line. CAUTION In accordance with FCC Rules, Part 68.218 (b), you must notify the telephone company prior to disconnecting the adapter from the line or turning off the power to the adapter’s host system. Without this prior notification, the carrier might temporarily discontinue your T1/PRI service.

BUsing the SynWatch Utility B Overview The SynWatch utility is a protocol analyzer that enables you to watch frames exchanged between the adapter and the ISDN network. This powerful utility helps you track communication establishment on the ISDN D channel, as well as data traffic on ISDN B channels. Each ISDN channel has a stand-alone configuration, and can be selected or deselected. SynWatch provides diagnostics for ISDN connection failures.
Accessing Online Help Accessing Online Help For detailed information about the functions described in this appendix, see the SynWatch online help. You can access online help in the following ways: • Use the menu command Help to display the main online help. • Press F1 to display contextual help in a pop-up window. • Move the cursor over a window control to display a pop-up with the name of the control. Starting SynWatch NOTE The iSPAN-PRI is listed as the 5535 adapter in SynWatch dialogs.
Appendix B: Using the SynWatch Utility Figure B-1. Main SynWatch dialog The main SynWatch dialog has two sections: • The left side is the configuration panel. It displays the adapter description. The configuration panel is used to activate or deactivate frame watching. • The right side is the monitor panel. It displays exchanged frames.
Mouse Button Functions Mouse Button Functions Synwatch manages configuration panel mouse clicks as follows, depending on whether the ISDN channel is selected or deselected. Left-click the checkbox beside the channel to activate or deactivate frame watching for that channel. To select or deselect all of a port’s channels, leftclick the checkbox beside the port. To select or deselect all of an adapter’s ports, left-click the checkbox beside the adapter.
Appendix B: Using the SynWatch Utility the ISDN connection phase. For example, if a RAS connection fails (during either dial-in or dial-out), the first channel to watch is the ISDN D channel. To activate watching on an ISDN D channel: 1. Select the channel in the configuration panel of the Synwatch dialog. A list of watch modes appears: Figure B-2. ISDN D Channel Watch Modes 2. To activate frame logging, select one of the watch modes: – Select LAPD to see detailed descriptions of signalling frames.
Watching ISDN Channels Watching ISDN B Channels NOTE Before establishing a call, you cannot know which ISDN B channel will be used. Therefore, to be sure to capture call data, you must activate traces for all the ISDN channels. ISDN B channels are used to transmit data frames after an ISDN connection is established. The first few data frames exchanged between local and remote sites correspond to a second connection phase to allow the establishment of the upper layer (for example, the PPP protocol). 1.
Appendix B: Using the SynWatch Utility 2. To activate frame logging for the selected channel or port, select one of the watch modes (RAS uses the PPP Protocol): – X25 – PPP – Frame Relay – SDLC – QLLC – Hexadecimal Dump For detailed information about each watch mode, see SynWatch online help. Watching ISDN Layer 1 Alarms ISDN Layer 1 alarms are managed by the adapter, and are activated when physical events occur. To display these alarms using SynWatch: 1.
Stopping and Freezing the Display Stopping and Freezing the Display To stop watching channels and discard frame information, do the following: To stop watching… Deselect this… A channel the channel in the configuration panel. All of a port’s channels the port in the configuration panel. All of an adapter’s ports the adapter in the configuration panel. When you stop watching channels by deselecting the channel, port, or adapter, SynWatch discards all frame information for the affected channel(s).
Appendix B: Using the SynWatch Utility only an ISDN disconnection. Changing to LAPD displays more details about the cause of the disconnection (for example, user busy or user not responding). Changing the watch mode is also useful if you are watching an ISDN frame in Hexa Dump mode while PPP frames are being exchanged. Reinterpreting associated information in PPP Protocol mode makes this information more meaningful and easier to read.
Saving and Editing Frames Figure B-4. ISDN Channel Settings 3. Choose the font and/or color(s) you want to use for this channel, and click OK. SynWatch updates the monitor panel with your new settings immediately. Saving and Editing Frames You can use the SynWatch Save option to save all frame information recorded in the monitor panel as an ASCII (text) or binary file. You can read a text file using any text editor, but SynWatch cannot read or reinterpret the text file.
CUsing the LoopTest Utility C Overview The LoopTest utility enables you to check your ISDN line quickly and easily. It checks for electrical problems, hardware connectivity, and ISDN compatibility problems. LoopTest also tests the adapter’s ISDN line by establishing 2 ISDN B channels in a loopback connection. One channel is set up to accept incoming calls, and the other channel calls the first channel.
