beroNet offers the BN2S0, BN4S0 and the BN8S0 BRI ISDN cards, a powerful and flexible solution for the Open Source PBX Asterisk. Together with our channel-driver "chan_mISDN", which is covered by the GPL licensing agreement, you can easily add BRI ports to your Asterisk system. Our channel-driver is based on the new ISDN stack of the new Linux Kernel: mISDN (modular ISDN). The BNXS0 card series is available with 2, 4 or 8 S0 ports, which can be configured individually for each port for NT (Network Termination) or for TE (Terminal Equipment) mode. In either mode the card supports Point-To-Multi-Point mode or Point-To-Point mode. You can power each port (except BN8S0) with our power supply mlodule (BN-Power) to provide current to your Terminal Equipment.
