N.1 ISDN Card 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 Enreach.

This document will use SX2 QuadBRI, if both type of boards are characterized (SX2 QuadBRI and SX2-express DualPRI). 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 S
0) 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 SinglePRI and 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 DualPRI
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).
