A question that is by far [OT]: but still a bit electrical: Does any of you know of a product (converter/extenter box?) that extends an ISDN (BRI) interface over either a serial (synchronous or asynchronous) or 10 MHz Ethernet link? The reverse is very common (tranmitting Ethernet, serial etc. over ISDN), but we want do give a quick demo of ISDN over our product, and all we have currently available in our product is transparent serial and Ethernet and a big shortage in manpower...
