Safety Precautions

The following general safety precautions must be observed during all
phases of operation of this equipment. Failure to comply with these
precautions or with specific warnings elsewhere in this manual violates
safety standards of design, manufacture, and intended use of the
equipment. Interphase Corporation assumes no liability for the user’s
failure to comply with these requirements. As the user of the product,
you must observe all stated warnings and safety precautions in order to
safely operate the equipment in your environment.

Do Not Substitute Parts or Modify Equipment

Because of the danger of introducing additional hazards, do not install
substitute parts or perform any unauthorized modification of the
equipment. Contact your local Interphase representative for service and
repair to ensure that safety features are maintained.

Ground the Instrument

To minimize shock hazard, the equipment chassis and enclosure must be
connected to an electrical ground. The power cable must either be
plugged into an approved three-contact electrical outlet or used with a
three-contact to two-contact adapter, with the grounding wire (green)
firmly connected to an electrical ground (safety ground) at the power
outlet.

Do Not Operate in an Explosive Atmosphere

Do not operate the equipment in the presence of flammable gases or
fumes. Operation of any electrical equipment in such an environment
constitutes a definite safety hazard.

Keep away from Live Circuits

Do not install or replace the component with power cables connected.
Under certain conditions, dangerous voltages may exist even with the
power cable removed. To avoid injuries, always disconnect power and
discharge circuits before touching them.

Telephone Lines Unsafe Voltages

As unsafe voltages (Telecommunication Network Voltages) exist on
ISDN lines, safety precautions must be taken to prevent contact with any
dangerous area of the system.

WARNING

■ The ISDN cable(s) must remain disconnected from the

telecommunications system until the card has been
installed in the system.

■ The installation of the card in the host system must be

done in a way that ensures at least 2mm of air gap
between the Printed Circuit Board (PCB) card and any
other components in the host system, so that the
unsafe area remains located only on the ISDN card.

■ The modem card must only be used in a host system

with a screw-down cover / lid in order to protect the
operator.

Telephone Wiring Warnings

Never install telephone wiring during a lightning storm. Never install
telephone jacks in wet locations unless the jack is specifically designed
for wet locations. Never touch non-isolated telephone wires or terminals
unless the telephone line has been disconnected at the network interface.
Any intervention on the card or in its proximity should be made with the
telephone connector unplugged.

Observe Dangerous Procedure Warnings

Warnings precede potentially dangerous procedures throughout this
manual. Instructions contained in the warnings must be followed. You
should also employ all other safety precautions which you deem
necessary for the operation of the equipment in your operating
environment.

WARNING

This equipment generates, uses, and can radiate
electromagnetic energy. It may cause or be susceptible to
electromagnetic interference (EMI) if not installed and
used in a cabinet with adequate EMI protection.

iSPAN PRI PCI ISDN Users Guide 7

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. If your adapter is a fiber adapter, do not
remove the connector cap(s) until you’re ready to install
the adapter.

Connecting the Adapter to an MVIP Bus

You must connect the adapter to an MVIP bus if you plan to
integrate the adapter with other MVIP telephony processing
adapters, such as voice, data, fax, video or image processing
adapters. To create a dedicated interconnection between these
adapters, connect a ribbon cable to the 40-pin, double-row,
right-angled headers on the top edge of all MVIP adapters.

For optimal electrical signal quality on the MVIP ribbon cable,
you must place the MVIP adapters in a specific order
(depending on the number of connections), and electrically
terminate two MVIP clock signals.

14 Interphase Corporation

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. In this
case, place the
cable.

On systems with more than five MVIP bus connections or
more than 90 pF of load on the clock lines, both ends of the

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. To provide the required electrical termination,
place two jumpers on the two 2-pin connectors located next to
the MVIP connector, as described in the following figure.

3Connecting to the Line

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.

If you are in Europe, skip to European E1/PRI Line on
page 23.

North America T1/PRI Line

When you connect the adapter to a North American T1/PRI
line, first determine the appropriate connection method,
cabling requirements, and link requirements.

Two T1/PR1 line configurations exist: DSX1 (short haul) and
DS1 (long haul). When the distance to your carrier is short
enough (less than 655 feet or 200 meters), you can generally
connect the adapter in a DSX1 configuration directly to the
T1/PR1 line. All iSPAN-PRI adapters support the DSX1
configuration.

iSPAN PRI PCI ISDN Users Guide 17

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. If your adapter does not
include this option (and if the distance is too long), you will
need to connect the adapter to an external CSU, which itself
will be connected to the metallic T1/PR1 interface.

Connecting directly to the line without a CSU

You can connect the iSPAN-PRI directly to the line without
any internal or external CSU if the distance to your carrier is
short enough (less than 655 feet or 200 meters). The line will
be in a DSX1 configuration (short haul). See Figure 3-1.

Less than 655 feet (200m)

Connecting directly to the line with an internal CSU

If your iSPAN-PRI adapter includes the internal CSU option,
you can connect it directly to the line and be up to 6200 feet
(1.8 km) far from your carrier. The line will be in a DS1
configuration (long haul).

The Network line build out compensates for the signal
attenuation due to the length of the cable between the
adapter and the switch.

Four values are available (expressed in dB):

• 0

• 7.5

• 15

• 22.5.

Select the value indicated by your Telco. If this
information is not available, use 0 dB.

Chapter 5: Setting Up WAN Firmware and Hardware

Option Description

Facility Data Link
Protocol(s)

Facility Data Link protocols are used to exchange
messages between the adapter and the remote end of the
network. Such messages are issued by the Telco to put
the adapter in loopback mode for testing when problems
occur. They are also used to transmit statistics about
physical transmission errors on the line.

Two protocols are available for the facility data link: the
ANSI-T1-403 and the ATT-54016 protocol. Both are
compatible with each other.

Use the protocol(s) indicated by your Telco. If this
information is unavailable, the best choice is to use both
protocols.

Problems and Possible Solutions

Problems and Possible Solutions

Problem Possible Solution(s)

Adapter is not
detected during
software
installation

This problem occurs if the system does not detect the
adapter after the setup program copies driver files to
the installation directory. (That is, the cards list is
empty on the WAN Adapter Setup dialog, as described
on page 33 of Installing the Software.)

When a message tells you to add a card:

1. Click OK.

2. Install (or reinstall) the adapter, as instructed in

Installing the Hardware on page 7.

3. If the WAN Adapter Setup still cannot detect the

adapter, see Computer does not boot up or Host
adapter not found on page 73.

When the adapter is installed, continue as follows:

1. From the Start menu, select Programs, then
INTERPHASE WAN Adapters, and then WAN
Setup.

2. Click Add on the main dialog, and do the following,

(as instructed in Installing the Software):

a. Configure the adapter’s ISDN ports, as described

in step 9 on page 35.

b. Start the WAN and RAS support software

installation as described in steps 1 through 6,
starting on page 28.

c. Complete the steps described in Setting up RAS

Support Properties on page 36, Setting Up ISDN
B Channels as RAS Ports on page 38, and
Checking the ISDN Line with LoopTest on

page 43.

Problem Possible Solution(s)

Chapter 7: Troubleshooting

Computer does
not boot up or
Host adapter not
found

Your PCI bus automatically configures the hardware
resources used by the adapter. Therefore, a resource
conflict (address or IRQ) is probably not the problem.

To resolve the problem:

1. Check to see whether the adapter is properly seated

in the PCI slot.

2. Try a different PCI slot.

3. Contact Interphase Technical Service.

LoopTest failed 1. Check the cable connection between the adapter and

the ISDN network.

2. Check that the ISDN switch type configured for the

adapter matches the switch the adapter is using.

3. Check the phone number.

4. For more detailed information, see Understanding

LoopTest Messages on page 94.

RAS Dial-out
failed

The following possible solutions assume a successful
LoopTest. (If you do not know how to check the
following items, see Index of Common Tasks on
page 115.)

1. Check to see whether at least one ISDN RAS port is

configured to make outgoing calls.

2. Check that the protocol(s) used by the remote user

(IP, IPX/SPX, or NetBEUI) are configured in RAS
dial-out protocols.

3. Check your user ID and password.

4. Use SynWatch to see if an ISDN connection

problem exists. (Does SynWatch see the ISDN call
in progress? Is this call accepted by the remote
system?)

5. Use SynWatch to see if a PPP negotiation problem

exists.

If you do not know how to check the following items,
see Index of Common Tasks on page 115:

1. Use the Event Viewer from Windows NT
Administrative Tools to see if the Remote Access

Service is successfully initialized.

2. Make sure at least one ISDN RAS port is allowed to
accept incoming calls.

3. Use Remote Access Admin from Windows NT
Administrative Tools to see if ISDN RAS

incoming ports are active.

4. Make sure your system administrator has given the
remote user right to connect.

5. Check that the protocol(s) used by the remote user
(IP, IPX/SPX, or NetBEUI) are configured in the
RAS server.

6. Use SynWatch to see if an ISDN connection
problem exists. (Does SynWatch see the ISDN call
in progress? Is this call accepted by the remote
system?)

7. Use SynWatch to see if a PPP negotiation problem
exists. Check the remote user ID and password.

Select the Enable Multilink option in the RAS
Network Configuration. (See Index of Common Tasks
on page 115.)

Multilink
connection does
not connect all
ISDN channels
required

1. Make sure that your ISDN subscription and the

remote ISDN subscription offer as many B channels
as the multilink requires.

2. Make sure that the number of free ISDN channels is
sufficient for this multilink call. (Check both sides
of the connection).

Problem Possible Solution(s)

Chapter 7: Troubleshooting

RAS initialization
failed in the
driver-event log

No valid
configuration

message in
SynWatch
configuration
panel

CSU activation
failed at load time

Look up the failure cause in your Microsoft RAS
documentation.

1. Check whether the adapter and the associated

drivers are installed correctly. (See Index of
Common Tasks on page 115.)

2. In the WAN Adapter Setup program, check that

the ISDN Layer is present in the adapter microcode.

If a message appears at load time informing you that
the CSU activation failed, you probably entered an
invalid password for CSU activation.

Enter the password again to activate the CSU and
reload. See Editing DS1 Properties (North America

BUsing the SynWatch

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.
It helps you detect PPP connection failures (for example, PPP
negotiation using Remote Access Service).

SynWatch interprets exchanged frames according to several
protocols. (Remote Access Service uses the PPP protocol.) It
displays these frames according to the appropriate protocol.

This appendix explains how to do various SynWatch tasks,
such as:

• Access online help
