N.2 ISDN boards SX2-express SinglePRI / SX2-express DualPRI
ISDN Interface
*SX2-express SinglePRI: 1 x PRI2m interface orSX2-express DualPRI: 2 x PRI 2m-interface
*Each line can be configured individually using a jumper field for the TE or NT mode.
*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.
*A maximum of 4 different cards (SX2 QuadBRI, SX2 SinglePRI and SX2 DualPRI) can be used in one PC. In doing so, a maximum of 76 B channels will be supported.
PCM Highway
*Tact synchronization is only possible between the different SX2-express cards. The cards are connected with a ribbon cable.
*2/4/8 Mbit/s data transfer rate
*Chipset: Exar XRT86VL
*6 DIP Switches
*Exact 32,768 MHz quartz oscillator
*PCIe x1 Interface
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 cards in the download area of the homepage:
