ISDN board SX2 QuadBRI
The SX2 QuadBRI is an ISDN card with four S0 connections. It works with Cologne Chip HFC-4S and was developed especially for the use with SwyxWare. It is manufactured exclusively for Swyx.
* 
This document will use SX2 QuadBRI, if both type of boards are characterized (SX2 QuadBRI and SX2-express QuadBRI). Differences, e.g. in the power configuration, are pointed out especially.
ISDN Interface
* 4 x BRI interface
* Each line can be configured individually using a jumper field for the TE or NT mode. The BRI connector (adapter to use an internal S0) is not necessary for the SX2 QuadBRI
* Short circuit resistance is provided for the ISDN connection via a special fuse (non-blowing, auto-recovery)
* Line termination (100Ohm) is adjustable for each connection individually via a DIP switch.
* A maximum of 4 different cards (SX2 QuadBRI, SX2 SinglePRIand SX2 DualPRI) can be used in one computer. 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
* SX2 QuadBRI
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.
* SX2-express QuadBRI
The board has a PCI express x1 Interface without any further configuration.
PCM Highway
* Tact synchronization between the different SX2 cards is possible. The cards are connected with a ribbon cable.
* 
A mixed usage of PCI and PCI-express board is not supported (incompatible plugs).
* 2/4/8 Mbit/s data transfer rate
* Chipset: Cologne Chip HFC-4S Chip
* Exact 49,152 MHz quartz oscillator
* 512x8bit serial EEPROM for programming the PCI configuration information

General purpose I/O
* Four two-color LEDs (red/green) on the mounting bracket of the SX2 QuadBRI
* Three DIP switches that can be used for the identification of the card
