Somewhat unknown PCI card for basic rate ISDN (I think from the chipset on board), this card would appear to provide two basic rate ISDN inputs on RJ45 and one analogue phone output on RJ11. Chipset on board is two Siemens PSB2115H for ISDN and one Siemens PSB2161T for the analogue phone.

I bought this thinking it was 2x ethernet and a modem, this was ages ago, and clearly wrong as I investigated further. Donated to the Telecoms Heritage Group.

It seems unsupported under Linux, none of the kernel modules recognise it either.
