SX2 DualPRI V2
• Properties
• 2 x PRI interface
• Each line can be configured individually using a jumper field for the TE or NT mode.
• Line termination (120 Ohm or 75 Ohm) is adjustable for each connection individually
via a DIP switch.
• Failover Relay on the SX2 DualPRI. This enables the two lines to be directly connected
to each other in the event of power failure or software problems, so that a PRI external
line can be looped through the card. This can be used for standby scenarios.
• A maximum of 4 different cards (SX2 QuadBRI, SX2 SinglePRIand SX2 DualPRI) can
be used in one PC. In doing so, a maximum of 76 B channels will be supported. Please
note that the SX2 DualPRI is counted as two cards because it will appear as two network
cards in the Windows device manager.
PCI Interface
PCI Interface for 3.3V and 5V PCI 2.2 slots. If necessary, 5V is reduced to 3.3V using a
voltage regulator located on the card.
PCM Highway
• Tact synchronization between the different SX2 cards is possible. The cards are
connected with a ribbon cable.
• 2/4/8 Mbit/s data transfer rate
• Chipset: Cologne Chip HFC-4S Chip
• Exact 32,768 MHz quartz oscillator
• 512x8bitserialEEPROMforprogrammingthePCIconfigurationinformation
General purpose I/O
• Four LEDs (red/green) on the mounting bracket of the ISDN card per PRI interface
• Four DIP switches per PRI interface that can be used for the identification of the card
• You will find more recent drivers for the SX2 in the download area of the homepage:
http://www.swyx.com/support/index.html.
• Installation of the ISDN PC Cards
The ISDN card can be installed in the same PC on which the SwyxServer is also installed. In
the standard installation, the SwyxGate service is also installed. This service controls the
ISDN lines that appear in the SwyxWare-Administration as an ISDN trunk.
In order to be able to install a SwyxGate on a separate PC, the SwyxServer must already be
installed and operable. For the SwyxGate installation you will need
• the server name and
• the name of the domain account, which was created in preparation for the installation of
the SwyxServer.
Before the ISDN cards are inserted, they must be configured for operation.
A maximum of 4 different cards (SX2 QuadBRI, SX2 SinglePRIand SX2 DualPRI) can be
used in one PC. In doing so, a maximum of 76 B channels will be supported. Please note that
the SX2 DualPRI is counted as two cards because it will appear as two network cards in the
Windows device manager.

• Preparation of the SX2 DualPRI V2
The connection configuration and the line termination must be configured for each E1
connection of the SX2 DualPRI V2 before it is inserted.
Requirement for further description: The SX2 DualPRI V2 is lying in front of you with the
PCI plug strip facing down and the E1 connections to the left.
Image 1-1 Schematic representation of SX2 DualPRI V2
Two jumper fields, which are in the near vicinity of the E1 connection plug, are assigned to
each E1 connection. In the following, the field with two jumpers will be referred to as SB2
and the field with five jumpers will be referred to as SB5. The suffixes L, R, O and U
indicate whether all jumpers of the respective jumper field are inserted to the left (L), to the
right (R), above (O) or below (U). SB5R means, for example, that all jumpers of the SB5
field are inserted on the right.

Configuration of the Line Termination
On the right next to the plug bridge fields for each connection you will find a two-pole DIP
switch with which the line termination can be configured.
• If both pins of the switch are in the "OFF" position, no termination is switched on.
• If the left pin is on the "OFF" position and the right pin is on the "ON" position, this
means that this has a 120 ohm line termination.
• If the left pin is on the "ON" position and the right pin is on the "OFF" position, this
means that this has a 75 ohm line termination.

Configuration of the PCI bus power supply
On the lower right side of the SX2 DualPRI V2 is a three-pole jumper field for setting the
PCI bus power supply.
Make sure that the jumper is at the correct setting for the PC main board.
Lower for an environment with 3 V, upper for an environment with 5 V, which will be found
on older main boards.

SwyxStandby support
The card supports the SwyxWare option pack SwyxStandby.
In order to activate this function on the SX2 DualPRI V2, please make sure that the six-pole
jumper is inserted between the two ISDN connections; if this jumper is not present, the card
cannot support the standby option.
For information on configuring the SX2 DualPRI V2 before insertion, so that the existing
relay can be used, please refer to the SwyxWare documentation.

Configuration of the Interrupt assignment
In the middle of the SX2 DualPRI is a three-pole jumper field.
Make sure that the plug is in the left position. It is thereby ensured that separate interrupts
are applied, as required in the driver software.

PCM bus connection
The SX2 DualPRI V2 has two 20-pole jacks for connection with an optional PCM cable.
The upper jack is the output. The lower jack is the input. Connect the SX2 cards with the
PCM cable, by connecting the output jack of one card to the input jack of another card.
LED Status Display
Each E1 connection of the SX2 DualPRI V2 has a status display consisting of two red and
two green LEDs.

• Installation of the software for the ISDN card
After the card has been installed, it will automatically be recognized the next time the
computer is booted and a request for the installation of the driver software will appear.
This is how you install the drivers for the ISDN card
1. Follow the instructions given by the hardware wizard.
2. When you are asked to enter the source for the driver, select “Enter other source”.
3. Put the CD in your CD ROM drive.
Click „Next>“.
4. Enter the path on the SwyxWare CD for the driver files on the SwyxWare CD
"ISDN\SX2 Standard Driver"
During the installation of the driver you will be asked to enter the ISDN switching type or
the D-channel protocol.
5. Select the ISDN exchange type or the switch protocol used by your telephone company
(in Europe this is Euro-ISDN (DSS1)).
Click „Next>“.
6. Please follow the instructions and click on „Finish“.
You can check to see if the driver installation was successful by checking the entries in the
Device Manager in the ‘Network Cards’ category. You will find more information on the
Device Manager in SwyxWare documentation.
You can check whether the installed ISDN cards functions properly by using the utilities
supplied on the SwyxWare-CD. For further information please refer to the SwyxWare
documentation.
• Configuration of the ISDN Card
If you would like to connect the card to a direct dialing in line, you must make some
configuration changes fort he ISDN PC card driver.
You can change the defined parameters in the driver software of the ISDN card at a later
point in time.
This is how you modify the ISDN PC card driver configuration
1. Run computer management, the simplest possibility is to use the shortcut menu for "My
Computer" on the Windows Desktop
2. Select “Manage”.
The Microsoft Management Console (MMC) will be started.
3. Select “Device Manager” in the console structure.
A list of all installed devices will now be shown on the right. There you will find the
following entry under “Network Cards”: “SX2 DualPRI".
4. Enter the appropriate settings under “Properties”:
• Select “ISDN Parameters” on the “Advanced” tab.
Select the “Port” tab in the dialog which is displayed.
• To switch to a line configured for direct dialing-in, please choose “Point to Point” and
close both this tab and the previous tab by clicking on “OK”.
Tip: If the line of an SX2 card is configured, the LED which is associated with this line will
blink. This simplifies the identification when operating several SX2 cards.
